Will a RT bumper weigh down my front enough to decrease my sway. I sit a little higher in front after my 2" lift and think I need to repace my steering stablizer also. Maybee stiffer shocks, I have Bilstiens but after 70 or so things start to wander a little more than I'm used to. Thank for any sugestions. Mike

1. Check your allignment and your swivel ball preload and adjust as necessary.
2. Odds are you are experiencing problems because of the change in castor due to the lift. If you want to "fix" it you probabaly should get castor correct radius arms.

Or you can go the cheap route that I did and use the castor correction bushings - it has solved my problems (at least for now). I've had the bushings in with both my OME and now my RTE 2" springs and it did eliminate that funky front end wander

By John on Wednesday, August 08, 2001 - 09:12 am: Edit

Get a 200 lb friend to sit on the hood as you drive it...Not really...A RTE bumper weighs in at 115 lbs, so with a winch as well....200 lbs which equates to about 1/2", maybe 3/4". Maybe enough to bring the caster back in, maybe not. Ron or Bills suggestion should proberly be heeded. And like I said yesterday, I am not to sure about Bilsteins on lifted trucks(slowly developing opinion)

By Alex Schubow (Alex) on Wednesday, August 08, 2001 - 01:19 pm: Edit

John,

Are you referreing to the stock-replacement Bilsteins or the racing shocks?

Thanks guys I think I'm getting used to it already, high speed braking is a bit scary, so I will check on the castor bushings. I guess I just want extra reasons to get one of your super cool bumpers John. I think I better not look at the RTE sight for a few days it can make me go crazy thinking about the fun possibilities.

By Mike B. on Wednesday, August 08, 2001 - 02:38 pm: Edit

I had a fair amount of wander after I did the RoverTym 2" springs and Rancho Shocks. I have a SafariGard front bumper and SuperWinch X9 winch. I had the front end aligned after the upgrade. I started messing around with the adjustments on the shocks and found that if I set the front shocks to 3 and the rears to 4 it handles nicely. With the shocks set to 3 in front and 3 in back it drove like a wet noodle going down the road at 70mph.

I hope this helps.
Thanks,
Mike B.

Mike, Which Ranchos are you running? the 900s? and Where do I find the castor correction bushings? To buy I mean.

By Mike B. on Wednesday, August 08, 2001 - 03:37 pm: Edit

Here is my setup:

Rancho 9207 front shocks
Rancho 9234 rear
RoverTym upper shock mounts
RoverTym quiet cones
RoverTym 2" springs
RoverTym quick disconnects in the rear
SafariGard 3.5" bump stops
Custom Made RoverTym Steering Dampner Relocation kit using the stock tie rods and a D90 OME Steering Dampner

Thanks,
Mike B.

By Mike B. on Wednesday, August 08, 2001 - 03:38 pm: Edit

Oops, make that 9027s in the front, not 9207s.

By John on Wednesday, August 08, 2001 - 03:52 pm: Edit

9207 is correct....

By Ho Chung (Ho) on Wednesday, August 08, 2001 - 08:24 pm: Edit

the caster correcting bushings are real thin and wont' last long.

better way is to go with caster corrected radius arms from rovertym.

OR,

TT in the front. that should keep you in line as well.

By Ali on Thursday, August 09, 2001 - 04:56 am: Edit

Just out of curiousity, what's the orientation of the castor correcting bushings in the radius arms? I have a set laying around so I wanted to try them on as an experiment.

By Ho Chung (Ho) on Thursday, August 09, 2001 - 05:12 am: Edit

install them so that the axle will rotate and make the pinion go down.

By Ali on Thursday, August 09, 2001 - 07:27 am: Edit

Thanks Ho, that helps me a lot. I can see already that this will decrease the pinion angle with respect to the floor but increase the U-joint angle. While this improves castor, vibes will increase, thereby requiring a CV driveshaft.

By pk on Thursday, August 09, 2001 - 07:40 am: Edit

Those bushings will limit your front flex. If off road front articulation is important to you (it should be since Rovers are lacking some front flex anyway), then forget the bushings and get the arms or a TT.

By Ron on Thursday, August 09, 2001 - 08:03 am: Edit

Ali, this is not necessarily the case as the angle increases but the angles become closer to being the same (dif and t-case should be parrellel with a non cv shaft), so it might actually make it better.

Ron

PS can't say anything about the TT as I had no driveability problems before the install

By Perrone Ford on Thursday, August 09, 2001 - 01:23 pm: Edit

What?

Ali had it right, his U-joints are going to be SINGING depending on the lift height. There is no way correcting castor will improve his u-joint situation. And yes the dif and the t-case should be parralel but they should be inline. The further you move them out of plane, the larger the angle at the u-joint. Always a bad thing.

Ok, what about shocks? should I try the ranchos first? or radius arms? My Bilstiens are kinda older but is this mor of a prob because of the arms?

By Kyle Van Tassel (Kyle) on Thursday, August 09, 2001 - 04:13 pm: Edit

Hmmm , for what we are dealing with here perrone you are wrong. if the pinion is pointing up and the Tcase output is pointing straight out you have a problem without a double cardan. To reduce vibs and noise the pinion should match the T case output angle. Yes once you get way up in the air thats a no no but this thing aint way up in the air.

Mike get the wieght on the truck first that you are going to end up with before you start spending cash on things that are going to change after you do so.

Kyle

By Perrone Ford on Thursday, August 09, 2001 - 06:19 pm: Edit

Ok Kyle,

Maybe I just read it wrong. Usually by the time someone is considering a bent radius arm, your are looking at a D.C. driveshaft to fix the vibe problems. I'm sitting on about a 4" lift with the stock arms. And surprisingly I am not having any vibe problems. But I KNOW when I correct the arms, I'll have to get a new driveshaft!

-P

By Ron on Friday, August 10, 2001 - 03:15 am: Edit

But I KNOW when I correct the arms, I'll have to get a new
driveshaft!

Probably not, actually.

Take some angle measurements and look, you should even be able to request the castor correction to get the two angles identical. One thing going for you versus us (discos and 87-88 RR) is that you front shaft is longer than ours as you have the VCU borg warner T-box.

By Mike J. (Mudd) on Friday, August 10, 2001 - 03:48 am: Edit

Ok, I have a little vibe decellerating at 70-60 or so but my main concern is loose feeling sway at higher speeds. I am seriously considering the adjustable Ranchos 9207, 9234, plus a new steering stableizer. Do you think they will help? and I could crank em up when I carry a load. Sounds good to me but... You guys who have tried this let me know. Thanks again for all your help. Mike

By Ho Chung (Ho) on Friday, August 10, 2001 - 04:28 am: Edit

mike,
i doubt that the shocks will help.
it's got more to do with caster.
are your tires in good shape? tire pressure?

those will affect your straight line stability much more than the shocks will.

By Mike B. on Friday, August 10, 2001 - 02:51 pm: Edit

I had the loose feeling at highway speeds after going with the RoverTym 2" springs. I re-aligned the front end and adjusted my RS9000 shocks (setting #4) to make them stiffer. That did the trick for me.

Thanks,
Mike B.
