I'm getting the occasional shutter while I'm driving and have no clue what's causing it. Having a hard time pin pointing as it only happens once in a while. For the most part while I'm driving the whole vehicle will shutter or shake really bad. This would be at speed around 60-65mph. If I let go of the gas it would go away and when I reapply it sometimes comes back or it would just go away. I also don't loose any power. It just seems to happen as I can't recreate the problem. I have checked the tires, driveshafts and for any loose parts underneath. So what am I dealing with? Bad u-joints, seem ok to me. Out of balance driveshafts, wouldn't the shutter be constant. Did a search and only thing which I found was the VSS. Are these systoms of the VSS or is it something else? Background...97 D1 with 2in lift, 235/85s, rear DC driveshaft with stock front. Thanks in advance for your help. Brian | ||

I had a similar issue with a car, it turned out to be the 3|4 clutch pack in the Auto trans was starting to wear out. | ||

I am having a shutter at 30MPH when I hit bumps or pot holes on city streets. The steering wheel with bounce back and forth violently for a brief second and then go away until I hit another bump. Is this what the steering stabilizer is for - and should I replace mine? '97 with 64k miles. Also - shocks look original... | ||
| Joey (Joey4420) Senior Member Username: Joey4420 Post Number: 559 Registered: 04-2003 |
If it is violently back and forth then I would say steering stabilizer or a very bad ball joint or wheel bearing. | ||
| Bill Bettridge (Billb) Dweb Lounge Member Username: Billb Post Number: 1473 Registered: 02-2002 |
Brad - your problem is most likely swivel preload and/or steering damper. Check swivels first Bill | ||
| Brian Fransson (Brian) Member Username: Brian Post Number: 47 Registered: 12-2001 |
Joey Would a bad ball joint or wheel bearing or then the steering stabilizer affect the entire vehicle like that? When it starts to shake everything from my hood to the steering wheel to everything else vibrates...then just stops. I can go about two days, even more, without any problems. It is not a persistant problem. Thanks Brian | ||

check your rotoflex. the vibration happened to me as well when drivng at freeway speeds. if the rubber coupler is damaged it will cause the intermittent shaking/vibration. the rotoflex is a rubber coupler located in the middle of the drive shaft. | ||
| Joey (Joey4420) Senior Member Username: Joey4420 Post Number: 560 Registered: 04-2003 |
As per your profile...if that is your rover driving through the water... When was the last time you checked your swivel grease. I would have to agree with Bill if you drive in water. | ||
| Andrew Maier (Newman) Senior Member Username: Newman Post Number: 557 Registered: 04-2003 |
Panhard rod bushings can and do cause this type of vibration. | ||
| Dean Chrismon (Chrismonda) Member Username: Chrismonda Post Number: 165 Registered: 12-2002 |
Brian I am having the same problem with mine. It shudders at about 70-75 mph. I have had the front axles re done but I have not checked the roto flex. I do notice that when I do the routine greasing of the drive train it reduces it slightly. Oh my rig has 116k I may need to re do the bearings. | ||
| Bill Bettridge (Billb) Dweb Lounge Member Username: Billb Post Number: 1475 Registered: 02-2002 |
FYI - swivel preload has little to do with driving in water - just age and swivel pin/bearing wear. Bill | ||
| Brian Fransson (Brian) Member Username: Brian Post Number: 48 Registered: 12-2001 |
Yeah...That's me in the water. It's been awhile since the swivel grease has been done. Will check and re-grease. Also will check out the panhard bushings. Raymond, I don't have the rotoflex back there, thanks for the suggestion though. Dean, I'm curious...are they symtoms like mine. Just comes and goes and is directly related with how you are on the gas. Meaning when you are driving all will be fine then you let go of the gas to slow down then speed up with a vibration. Once you let go of the gas again and coast it will go away. This all driving around 60-70mph. | ||

I had the same sort of problem, and it was the steering stabilizer... | ||
| Kevin Fedyk (Kovert) Member Username: Kovert Post Number: 104 Registered: 05-2003 |
Brian, hate to say it, but more than likely not a stabilizer problem. I have the same thing and haven't been able to narrow it down. Going fast on the highway, someone swerves in, let off the gas, go to get back on it and BAM the shudder starts. I have replaced the stabilzer, checked the u-joints, and not sure what else, but it doesn't seem suspension related as it does not happen other than described as above. | ||
| Dean Chrismon (Chrismonda) Member Username: Chrismonda Post Number: 168 Registered: 12-2002 |
Yeah Brian they will go away when I let of the gas,It shakes the whole vehicle. I had my panhard rods tightened last summer.But what you describe about the systems of your rig sound alot like mine. | ||
| Glenn Guinto (Glenn) Senior Member Username: Glenn Post Number: 822 Registered: 02-2002 |
Brian, I agree with Raymond on the Rotoflex call. John was just dealing with this issue on his wife's 96 D1. If you need one, John has one laying around. Email him. Glenn P.S. When are we hitting the trails? I hope all is well. | ||
| Kevin Fedyk (Kovert) Member Username: Kovert Post Number: 105 Registered: 05-2003 |
Yes but his truck as mine does not have a ROTOFLEX. He must have the U-Joint instead. | ||
| Brian Fransson (Brian) Member Username: Brian Post Number: 49 Registered: 12-2001 |
Wow! So I'm not the only one then. Dean and Kevin...We have definetly have the same problem then. Are you running stock or are you modified at all? I'm starting to think that it may be transmission or engine related. Glenn...How's it going? I'm fine over here. My '97 never had a rotoflex and I'm now running a Great Basin Rover double cardon driveshaft. We should plan something one Saturday. Brian | ||
| Glenn Guinto (Glenn) Senior Member Username: Glenn Post Number: 823 Registered: 02-2002 |
doh... Sorry, I was under the impression that all pre-99 had Rotoflex. TTYL! Glenn | ||
| Kevin Fedyk (Kovert) Member Username: Kovert Post Number: 106 Registered: 05-2003 |
Stock. 99 D1, with about 86K on the clock. I did replace the VSS also which did nothing... | ||
| Brian Fransson (Brian) Member Username: Brian Post Number: 50 Registered: 12-2001 |
So I can rule out the tires, lift, rear driveshaft and the VSS. When it first happened I had asked my Father what he thought and he mentioned a misfire, maybe running on 7 cylinders. Maybe passing bad gas. Thing is wouldn't these trigger a check engine light. I'm just over 91,000 miles Any thoughts. | ||
| Kevin Fedyk (Kovert) Member Username: Kovert Post Number: 107 Registered: 05-2003 |
Valves. Hate to say it, but I'm sure someone will. I just beat them to the punch. I did have a code trip once on my truck though. Misfire on Cylinder 6 | ||
| Geoff 93 RRC (Geoff) Member Username: Geoff Post Number: 240 Registered: 11-2002 |
I have it occaisionally and think its the front output shaft from the transfer case. If I take off the driveshaft and wiggle the flange there is noticeable side to side play. | ||
| Brian Fransson (Brian) Member Username: Brian Post Number: 51 Registered: 12-2001 |
Ok. Is it possible for sticking or bad valves to cause the entire truck to shake like that? I had thought you would only see a loss of power. I can't determine if I get loss of power. Running 235/85's, it's slow as is. Also with a misfire, sometimes you don't even notice it. But if one cylider goes dead for a few seconds what would be the outcome? | ||
| Brian Fransson (Brian) Member Username: Brian Post Number: 52 Registered: 12-2001 |
The driveshafts seem ok. There is a bit of play on both, but I think that is just normal. I would have to double check the side to side movement. Maybe something is getting out of alignment? | ||
| Kevin Fedyk (Kovert) Member Username: Kovert Post Number: 108 Registered: 05-2003 |
I'll have to sneak under my truck tomorrow and check the driveshafts myself. I usually get that vibration around the same speeds that you do. I'm just regurgitating what dealers seem to say everytime a rover has a problem  BAD VALVES. If you find out though, let me know, I'm following this closely and will add anything I find that might be beneficial. | ||
| Will Cupp (W_cupp) Senior Member Username: W_cupp Post Number: 346 Registered: 07-2003 |
My 99 does this time to time. I can be running down the interstate at 70-80mph, let off the gas, get back on the gas and have slight shutter. This is not the "Death Wobble" like on my 97. It does not seem to be coming from the drive train, or steering. It is more like a misfire, or plug only half way fireing. I replaced the plugs and wires, but it did not solve the problem, but made it a little better. I run 93 Octane all the time, but once my wife put in 86? and it got real bad. | ||
| Brian Fransson (Brian) Member Username: Brian Post Number: 53 Registered: 12-2001 |
One more to try. Dry Gas. I don't think I have used any this year. Maybe there is some condensation in the tank and contaminated the fuel. | ||
| Richard D. Cronin (Wldkgdm) New Member Username: Wldkgdm Post Number: 11 Registered: 09-2003 |
I have had two '96 Disco's and both exhibited the same problem. Get up to hwy. speed or merging on to the hwy. and as the vehicle shifts to higher gear "V-B-V-B-V-B-V-B-V-B-V-B-V" The whole truck shudders....Let off the gas, reapply gas - still there, let off gas - coast the vehicle a bit - goes away after two or three tries. Happens maybe once, twice a week.....I thought it may have been a exhaust valve stuck in the closed position. Sometimes I can hear a faint tapping noise coming from the rocker assembly.....After checking U-joints (no rotoflex)panhard rod bushing, wheel bearings, tire rotations, tire balances, it has to be either the front output shaft from the T/case or an internal clutch pack issue with the LT230. | ||

I have one, and only one I can assure you, problem. My 96 D1 5 speed (new rotoflex, new driveline u-joiunts/flanges, compression great and within 10psi for the 8 cylinders, synthetic oil, new fuel filter) has the same damn problem. Speeds between 55 and 90 MPH. Loading makes no difference (hills or no hills). Problem been going on for 6 months, many hundreds of gallons of 91 petrol. Random case of the "stutter" and utter lack of engine force, for 5 to 10 seconds. My problem is definitely an engine power output problem - no response when the D1 is having a "seizure" to any position of the gas pedal. Bring on the Dilantin! The one constant is high, constant engine RPM. Slight correlation with time, as in slightly worse after 3+ hours at 90 MPH (good ole I-5 between Sacramento and the grapevine). It feels just like fuel starvation or a fouled/misfiring spark plug. The new plugs/wiring/disti cap/disti roto/timing check was easy - made no difference whatsoever. Checking for an intermittant problem in the fuel system has not been fruitful. Fuel injection cleaner (whatever the f*&^ that stuff does) - no difference. KN filter. New battery. New air freshener. Y'know, all of it except no new fuel pump, no new fuel injectors, no new ECU. I've given up. I'm bored with it. I'll live with it. Unless one of you can devise a solution. Besides, off road it never happens and that's why I own this thing in the first place! Don't ever underestimate the power of denial. Did I mention I absolutely love this D1 and it'll be a short, cold day in hell before I ever buy anything except a 96 to 98 D1? I hope I'm not bidding against y'all for the last rusty one in existence in 30 years or so! Dan | ||
| Aaron Richardet (Draaronr) Senior Member Username: Draaronr Post Number: 439 Registered: 09-2002 |
Ha Ha 97D1 stock same symptoms. You guys must have bought your trucks used. When you bought them new there was a shutter option right after the rear air package. I assumed that was England slang for window tint.( that was obviously a joke.) Mine has done it for 3-4 years now. Changed all plugs, wires, and etc. New tires twice, several balances and alignments. Shutter hangs in there. I notice it happens right around 67-70 faster no problem slower no problem. I just try to hurry through that speed. | ||

I know that some Fords were notorious for a bad shudder when the torque converter would try to engage its 1:1 lock at highway speeds. My old truck got to where it did it almost everytime, and my wife's explorer does it occasionally - felt like you ran over the "turtles" on the side of the road. Would always do it when merging onto freeway or after you let off the gas on the freeway then applied it again - the convertor would unlock when you let off the gas to coast, then try to lock again. A tranmission fluid change always cured it for 30k miles or so. Don't know if the Rovers are prone to the same thing or not. I guess you see if it happens with the transmission in 3rd instead of OD, but it might try to lock in 3rd also to save gas? Steve | ||
| Geoff 93 RRC (Geoff) Senior Member Username: Geoff Post Number: 260 Registered: 11-2002 |
Does this sound like the same symptoms: http://www.fourfold.org/LR_FAQ/Disco/Disco.Throttle.Problem.html | ||
| Kristopher March (Apexdisco) Senior Member Username: Apexdisco Post Number: 307 Registered: 02-2002 |
Yup, I've got the same problem in my 99 DI. Haven't experienced it in a while now, and I've been running 93 Octane. I just changed my fuel filter tonight and put in a bottle of fuel injector cleaner. I think the throttle sensor makes sense, as far as being a culprit. | ||
| Kevin Fedyk (Kovert) Member Username: Kovert Post Number: 109 Registered: 05-2003 |
All I know is I am having the same problem and it is driving me insane. I need to figure it out soon as D.C. driving can definitely be stop and go on the highway I have a 99 D1 by the way. I will change out my Fuel Filter this weekend, and possibly pull out the TPS and clean it. I should probably clean out the IACV but am unsure how to do that. | ||
| dagwood (Daggoneit) New Member Username: Daggoneit Post Number: 12 Registered: 09-2003 |
Thank you Geoff. I do believe we have the culprit. All the facts fit. Now for the acid test - a new TPS. $83.95 through NEBritish. It's a gamble I'll try. Stay tuned! Dan |
