New disco owner, someone please explain the transfer case/center diff. lock? How does the 4wd system work? | ||

Sorry forgot to add it is a 95 Disco | ||

Chris, the Disco is always in 4WD. The center diff is what makes it possible. Since you have a 95 there are 4 postions for yout center diff 4H Open - daily on-road driving. 4L Open - differing thoughts ... 4H Locked - differing thoughts ... 4L Locked - xtreme wheelin! ( i said "xtreme") whoO! When locked, the center diff splits the torque 50-50 front to rear. Also, if your truck hasnt been swithced to locked in a while, then you're in for some fun (trying to get it unstuck). I've found the easiest way is to shift the transmission to neutral at about 5mph, then try shifting the CDL. | ||

Chris, Here is some theory. http://auto.howstuffworks.com/four-wheel-drive.htm Then follow Eric and find some slippery stuff And have some practical fun. Mahn | ||

The CDL works by magic. If you can get it in and out of locked and unlocked while sitting still, you need to take a bow and say "ta-da", cause it's got to be frigging magic. | ||

chris-congrats in the new disco and welcome. there is a wealth of info on this site in the archives and in tech, discovery sections. here is another page i found useful for understanding the CDL: http://people.cornell.edu/pages/efe4/images/rover/difflock/discodifflock.htm i also emailed you offline with the manual text in case your disco came without this important little book. cheers, carl | ||
| Chris Sinclair (Coastiedisco) New Member Username: Coastiedisco Post Number: 3 Registered: 10-2003 |
Thanks, Basically what you are telling me is that unlike a typical transfer case there is a mechanism (CDL)? that allows for slippage between front and rear axles while the CDL is unlocked. While the CDL is engaged it forces the front and rear axles turn together like most other 4 wheel drive vehicles do when in 4 wheel drive. While the CDL is engaged what makes this system better than another 4 wheel drive vehicle? Other than the obvious full time 4 wheel drive applications. Thanks for the info. | ||

Chris, I think the biggest advantage that Rovers have over other 4wd vehicles while the CDL is locked is not so much in the 4wd capability but rather on how that capability gets to the ground. Solid axles front and rear (until'05) are though by many to be superior for off roading for their ability to clear obstacles. If you go up on rock, it lifts the center of the truck as well. Independent suspension would not lift the center of the truck as much. The Rover's ability to articulate the axles (meaning how far a side can drop while the other side is up) allows for a greater chance of contact with the ground thus more traction. The stiffness of the frame is what allows the truck to be abused on the trail, and yet ride as smooth as a mall crawler on the highway. When lesser vehicles are used the same way, you begin o see flexing of the body, and slight misalignment of doors. Crawl under your truck, an notice how all critical components are safely tucked away between the frame rails. So basically, when you buy a Rover, you get the most capable offroad truck right out of the box. With other vehicles, you need to modify them to get to the off-road performance level of a Rover. I think that's why Jeep came out with the Rubicon, essentially, a factory modified Jeep. | ||

i laugh at all the no-minds who knock jeeps. I have owned a dozen of them and just because I happen to have a rover in my driveway now dosent mean that i didnt think the world of my jeeps. I had a 71 commando with a 258inline 6 turbo 400 dana 44's front and rear with powerlocks all stock and it would go anywhere a stock disco will go . rover snobbery is just bullshit....yes they are great trucks but they are not the only trucks  | ||

I agree too. I still regret selling my Wrangler. I really did love that inline 6. Then again I regret selling my westfalia camper and 300ZX too. I will never sell the rover. | ||
| Jaime Crusellas (Jaime) Member Username: Jaime Post Number: 143 Registered: 05-2003 |
Thom, Where's the snobbery? The point of my comments was that a stock rover is the best 4x4 compared to a similar stock 4x4 of another make. And to equal that performance you would need to modify the other vehicle....Hmm... maybe my use of the phrase 'lesser vehicles' aggravated you? | ||
| Brian Dickens (Bri) Senior Member Username: Bri Post Number: 778 Registered: 08-2002 |
I think they are referring to "best" and "lesser vehicles". I am also not sure that all the things you say are technically accurate, but will let a real expert pick that apart. Some people may perceive this as snobbery even if you did not intend it that way. There really is no "best" vehicle. There is however a best vehicle for specific individuals needs. I am not knocking you personally, but I would put a stock TJ, CJ, Wrangler or Rubicon against a stock Disco any day. Maybe even a Cherokee. In fact I think you will find threads here that many are more impressed with the H2 than might admit and certainly an H1 is one impressive vehicle, right out of the box. In my book, it is the driver, not the vehicle that makes the biggest difference. So back to the thread, my own personal simple explanation. - No diff lock means that power goes to *any* one wheel. The wheel with least resistance. So if you lift/slip a wheel all power goes there and you are stuck. - With diff lock means that the transfer case diverts 50% power to the rear and 50% to the front. Of the front and rear only one tire will receive power, the one with the least resistance. Lift or lose traction on one front tire *and* one rear tire and you are stuck. - Add aftermarket lockers front and rear such as detroit or ARB and you then in diff lock you have 50% power to the front and 50% to the rear and all of the power goes to both wheels front and rear (the left and right are "locked" together. Lift or slip any tire and the power is still going to the others that have traction. Cheerio! Brian | ||
| Jaime Crusellas (Jaime) Member Username: Jaime Post Number: 145 Registered: 05-2003 |
Brian, I know what I was thinking when I said 'best' but I guess I didn't get it accross. I would not compare a disco to a TJ, CJ etc. I'd comare a Defender to those. The disco I'd compare to either a Cherokee, Montero, 4 runner, etc. the Hummers are in a class by themselves. | ||
| thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 411 Registered: 11-2002 |
Jaime, my comment was more aimed at Phillip's comments then yours....but now that I go back and reread yours here is my gut responce.
every jeep built before 1986 except the quadratrac equiped models when in 4 wheel drive sent power 50% front 50% rear. what makes the disco put the power to the ground so well is the lower gears and limber suspension.
I would say the rubicon is more a example of jeep answering the call to market just as they have over the last 6 decades. more people want to tackle tough trails so they are selling a product designed to drive the toughest trails. Kyle summed it best a while back when he said some of the people here started out in a disco and others of us are ending up in one. I think the world of Defenders and Discos, but I also recognize that there are tons of other trucks that are equally capable. Thom | ||
| Peter Matusov (Pmatusov) Senior Member Username: Pmatusov Post Number: 1121 Registered: 09-2002 |
Thom, this is an incorrect statement. Every 4WD jeep with low range, regardless of the year, had an ability to spin the front and rear driveshafts at the same rate. Is it what you meant? The quadratrac jeeps were like Range Rovers with the CDL open (limited slip center), and like locked-center Discos with CDL locked. The best of both worlds. | ||
| thom mathie (Muskyman) Senior Member Username: Muskyman Post Number: 415 Registered: 11-2002 |
peter, actually ...it was not a incorrect statement...I never addresed low or HI range. was just talking in 4 wheel drive period. just turns out yours is also a true statement | ||
| Greg Hirst (Gregh) Senior Member Username: Gregh Post Number: 351 Registered: 10-2002 |
I enjoy admiring and wheeling with anyone with a well thought out and set-up Jeep, FJ40, early Bronco, 'Binder, etc. However, a well set-up D90, SWB Gelaendewagen, Unimog, Pinzgauer, Haflinger, etc. means extra wood IMHO! | ||

Don't know how relevant this is, but has anyone read the December 2003 issue of Four Wheeler? They have the "10 Best Used Truck Bargains" and they list the Disco as "one of the most durable and capable SUVs in the world." lol, only reason why I even walked out of Barnes and Nobles with that magazine... | ||
| Matthew A. Barnes (Discoveryxd) Member Username: Discoveryxd Post Number: 102 Registered: 08-2003 |
Are you implying that saying the disco is one of the most durable and capable SUVs in the world is a joke? Or are you quoteing the magazine to prove a point about rovers being capable 4x4s? Matt | ||
| Peter Matusov (Pmatusov) Senior Member Username: Pmatusov Post Number: 1124 Registered: 09-2002 |
Thom, I hate to be anal, but - the statement I meant was about 50/50% power split between the axles. Just in case, it can only be achieved with an open center differential, during a straight-line driving on hard pavement. | ||

Jeep fans say what you want. I had a 2000 XJ. I would walk out of the house every morning and wish I had a Yugo. It had a 4 cyl., got 13 mpg, 110hp motor, and 65 mph top speed. What a sorry piece of shit......I cried when I traded it in on my Rover. I was so happy. | ||
| Peter Matusov (Pmatusov) Senior Member Username: Pmatusov Post Number: 1128 Registered: 09-2002 |
Bill, I had a 95 XJ with a 4-banger and stick shift. It would get 16 mpg in town and 24 on the highway, and its top speed would be governed by the side wind and your noise tolerance, not power. (I've spent about $200 on Dynamat, just to be able to talk to my passengers on the highway). I bet you had one with an automatic. A 4-banger with a slushbox is a bad idea in a truck! | ||

Hey Chris welcome to DiscoWeb, take your rig out off-road, find someone that knows how to use them and try each set up yourself first hand. That's how you'll trully know when to use what and how to use what, you already know 4H, you got three to go!!!! Have fun | ||

"Are you implying that saying the disco is one of the most durable and capable SUVs in the world is a joke? Or are you quoteing the magazine to prove a point about rovers being capable 4x4s? Matt" No, no, not a joke. I was just quoting to prove that rovers are capable 4x4s. That, and because it surprised me that it would be on the list of "10 best used truck bargains", since I never thought they would be really acknowledged on an American 4x4 magazine. Now, if they just did an article on a Disco with 38" Super Swampers, that would be friggin awesome.... But back to the question at hand, cuz I'm quite curious myself: When exactly would you use 4H Locked? | ||
| Matthew A. Barnes (Discoveryxd) Member Username: Discoveryxd Post Number: 108 Registered: 08-2003 |
I agree with you Ivan. I was watching a show called "sport Truck Connection" (I think that's the name) and they previewed a D2 with lots of ARB goodies and an OME lift. It surprised me because I never see LR's on TV shows like that. I like to watch "4x4 TV" also, and they had a show were they reviewed all the SUV's of 2003. They talked about all these different trucks and how capable they were, but they never said a word about the disco, range rover, or freelander. You think they would considering that those rigs would out preform most of the ones they listed. At the end of the show Land Rover is listed as one of there sponsors too. A small part of me likes the fact that LR's aren't all that popular (atleast where I live) because that makes all our modified ones so unique. I like driving down the highway and getting wierd looks because people have never seen a truck like mine. Diff lock is used when you are on slippery surfaces such as ice, snow, mud, wet grass. Make sure you dissengage it on hard surfaces to prevent "wind up" Matt | ||

You wanna get some strange looks, slap-on a Safari snorkel and people almost run into you looking and pointing. Old timers know what they from their days in the service. It is amazing how many people stare and point and it's not a booger hanging from my nose, so it's got to be the snorkel. Yup, has not a damn thing to do with CDL either. | ||

My wife really liked all of the attention she got while driving the disco...until she realized that all of these guys where checking out the truck and not her! My daughter makes me park as close to the school as possible when I pick her up because the boys like my truck! If only more females gave me that kind of attention! | ||
