2000 Jeep GC LTD - Quadra Drive Does Not Engage Front Wheels

Seems like I am only getting power to the rear wheels. There are no strange noises coming from the drive train, but unless I am in 4Lo, the truck handles like absolute **** in the snow or on ice - back tires spinning and fishtailing. It almost seems like I am only getting power to one rear wheel but I am not certain. Any idea if this is going to be an expensive re-build?

    I believe it is All Wheel Drive. My options are 4WD High, Neutral,and 4WD Low. It has the Quadra Drive NV247.

  • jss_mailingl Jan 07, 2009

    Well that does not sound too bad - I am sure it will be better than the $2K I paid to have the front and read diff on my '93 rebuilt.

    Thanks for your fast input!

The 247 doesnt use solenoids but oil pressure from a gerotor pumps driven by the front and rear driveshafts to a progressive coupler. a set of orifices and valves direct fluid to the coupler to determine how much torque is sent to which set of wheels

Jeep grand cherokee quadra drive


Differentials.

The Jeep Quadra Drive systems have a limited slip differential in the transfer case as well as the front and rear axles - which allows you to run all wheel drive on all surfaces. This matters because without limited slip capability your transfer case & axles would break.

Have your transfer case and axles serviced by a dealer, really a real dealer for Chrysler Jeep. These diffs and transfer cases can use unique gear oils that you don\'t want to mix up with regular gear oil.

That howling, clunking, grinding noise is your dog-clutches slipping (as designed) as you go around the corner.



Additional Details below:

So what\'s the Diff?



All differentials are is a way to allow for different wheels to travel different distances on the same vehicle. What-he-say? Yep, when we turn a corner all 4 wheels go a different distance around that corner... oh yeah well everybody knows that. Think about it, your making that hard left turn at your favorite Fast-Food joint; your left front wheel is 2 feet away from the curb, but the back left wheel rubs the curb... why?

As you make that 90 degree turn, your left back wheel travels 4 feet, your left front wheel travels 6 feet, your right rear wheel travels 7 feet, and your right front wheel travels 8 feet.



Ok you say, what\'s the big deal? A couple feet slip here a couple of feet slip there... Well remember your sticky rubber tires on dry asphalt don\'t really give very much and u-joints, axles shafts, and even pinion and ring gear damage can occur. Fortunately for us, Leonardo DaVinci (yeah really) saw this problem coming and designed the Open Differential. There are mini-gears inside your open differential that allow for that slippage, these mini-gears are called spider gears. Problem is when your in snow, ice, mud the spider gears of the open diff allow all your power to go to the wheel with the least traction (and your stuck).

Ok let\'s put another powered axle up front and call it 4x4. Umm no.

A normal 4x4 is not really true four wheel drive. At best it\'s the worst 2 wheels you\'ve got - driving you forward. Until both wheels on the same side are in a ditch, and your stuck.



Well what the heck Leonardo? I want something better than stuck!



The old-time dragster dudes of the 50\'s & 60\'s agreed with you and they welded those little spider gears together for true positraction across both wheels. Ever been close to a big monster truck in a parking lot and heard its tires chirping around the corner? Or an old Jeep crow-hopping it\'s way around a corner - Letting out little tire noises (like "erp" "erp" "erp")?

That\'s because these 4x4\'s have been modified to not have any differential action. None. This is great in a 1/4 mile dragster race or a mountain climbing rally car. A locked front differential can (and most likely will) cause you to crash... not good for daily drivers.



You\'re in luck, the Limited Slip Differential (LSD) has clutches instead of spider gears, which engage as wheel slippage increases. Subaru and Audi are 2 companies that really brought this to market with All Wheel Drive decades ago. Jeep and other SUV/Pickup manufacturers have utilized clutch-based LSD\'s as well. Clutch-based LSD\'s however, have a limited lifespan and can require special gear oils. When Clutch-based LSD\'s fail, they basically become an Open Diff.



Automatic locking differentials were brought to market in the 70\'s & 80\'s by companies like Detroit Locker, and these engage a fully locked set of gears as soon as any slippage occurs. Problem is it can become very difficult to steer, at all. Forget about U-turns, just go around the block. And while your at it, stop and pick up another set of tires because it will feel like you are dragging your outside tires around every corner.



Jeep and Daimler-Chrysler developed another type of LSD that utilizes a small hydraulic pump to engage a set of clutches and gears, which lasts much longer than traditional LSD\'s. It was called a Gerodisc differential, and it worked fairly well. Not as much traction as a full locker, but good LSD performance. The problem was the Gerodisc couldn\'t control itself in the car-washes, and would build-up pressure as the tires slipped over the soapy rollers, and launch the Grand Cherokee across the car wash. Yeah, it was freaky. So freaky that the National Car Wash Association of America (yeah they have an association, who knew?) prohibited all Grand Cherokees. Look it up.



The King Daddy of differentials is the selectable locker. These little gems are very expensive, but you get all the benefits of both the open diff for maneuvering, and lockers for traction only when needed.



So that noise, while it may not spell imminent doom, surely ain\'t good.

My rear differential is broken and i would like to engage my front wheels so i can just drive with them. the car is headed for the junk yard im just trying to get a few more weeks out of it. it has smart...


what you are describing can't be done-unless-no -the rear drive shaft will still drive the rear wheels-smart track ain't so smart. you could drop the rear drive shaft out but then you'd leak trany fluid all out the tailshaft-why not pick up rear end at the junkyard and install-cheers Denny

Why doesnt my 4x4 work on my 2000 jeep quadra drive i just got it and i took it to a mechanic and he said that if the 4x4 wasnt working then the car wouldnt run since its a 4x4 all time. the front wheels...


Quadratrack transfer units work by way of an internal fluid coupler (same as your mechanical clutch fan but bigger) It is always on but not always engaged. It engages when the rear wheels start to slip.
It should lock in low range though. (in low range you should not drive over 15mph).
if the front wheels won't engage at all, then either there is something wrong inside the transfer case or inside the front differential. Both are usually noisy if they have failed but I've seen some that the ring gear has been removed as well as the driveshaft (sometimes) after the diff has failed, so it can be driven. Find another shop that's more familiar with that unit and have them take a look at it if you don't see anything obvious.

How does the 4x4 drive work


normaly you drive in 2 wheel dive rear whee lls driving jeep
when you select 4 wheel high or 4 wheel low you engage all 4 wheels bring intthe front axle and all 4 wheels drive high box for slippery roads ice snow etc
important low box only for extreme conditions such as heavy mud deep snow etc
LOW MUST BE SELECTED WHEN STOPPED OTHER WISE DAMAGE TO TRANSMISSION
hope this helps

2000 jeep GC limited front axle problems


First thing to test is to see if the front driveshaft is getting engaged from the transfer case. With the vehicle in 4x4, and engine shut off, and in park, crawl under and try to turn the front driveshaft by hand. The driveshaft looks like a pipe that runs from the transfer case, located just behind the engine/transmission, to the front differential. If it rotates by hand, there is a problem with the transfer case. Some Jeeps have a vacuum actuator on the front diff that slides a collar inside the axle tube to engage it. I will watch for you findings, and you can leave me another message, and I will be happy to chat back with you on your findings.

How do I activate the 4 wheel drive for snow highway driving?


They didn't make Grand Cherokees in '86, so I assume you mean '96?

I'm also assuming it is indeed a 4x4 and not a two wheel drive...sorry, I have to ask!

All the V8's GC's were Quadra-Trac. Please confirm this with what is label on your shifter. If so, it should say "4Hi, N, and 4Lo".

The Quadra Trac system has a viscous coupling. Meaning, that when the rear wheels start to slip, it heats the coupling up, and engages the front wheels.

This system typically put about 95% of the power to the rear wheels, and only about 5% goes to the front during normal driving, so it's essentially in 2wd mode.

When you put the transmission shifter into neutral, and pull your transfer case down to 4lo, then you have all four wheels locked. Do not drive like this on dry pavement.

To answer your questions, the 4x4 should automatically engage when the rear wheels start to slip. It is a seamless transition and you really won't be able to tell.

If you're in real bad snow, then pull it down to 4lo. That'll lock all four wheels in and give you greatest traction.

Drive safe.

How Does Quadra Drive Work?


Under normal driving conditions, the system operates conventionally, and the majority of available torque is applied to the rear wheels. However, when front-to-rear wheel speed variations exist, the progressive differential transfers torque to the axle with the better traction, thus minimizing wheel spin and maximizing control.
The key to this design is a progressive coupling Progressive Coupling , which is supplied with pressurized oil by a gerotor style pump. The pump rotor and case are driven by the front and rear driveshafts respectively, and deliver pressurized oil flow to the coupling in proportion to their speed difference. The progressive coupling contains a multi-disc clutch pack that is alternately splined to the front and rear driveshafts, and controls torque variation between the front and rear driveshafts as dictated by the pump.
A set of orifices and valves control the speed-differential starting point and rate of torque transfer rise in the clutch. This allows the system to disregard the normal speed differences between axles that result from variations in front-to-rear loading and typical cornering.
Transfer case operating ranges are selected with a floor mounted shift lever. The shift lever is connected to the transfer case range lever by an adjustable cable. Range positions are marked on the shifter bezel plate
