Question about 2004 Jeep Grand Cherokee

1 Answer

4 wheel drive not working

We have a 2004 Jeep Grand Cherokee with Quadra Trac II. Torque is supposed to be transmitted to the front driveshaft as needed. However, it is not working. We have had the Jeep for three years and had never had any problems with the ALL TIME 4 wheel drive feature until this winter. Only the rear wheels spin when in the snow or in bad weather.

Sounds to me like the transfer case clutches are worn out. also the fluid could be low or dirty. try draining and refilling the transfercase with clean fluid. if it is still not working after driving it around for a few miles then you may need to replace or overhaul your transfercase

4 wheel drive is not working


so is AWD,? command trac or what trac?

no working means..... using or 4low,?
my wild guess: 1:
Quadra-Trac-II NV 247 Gerodisc system 1999+
got that? what you have for real MATTERS? we cant guess.
the 247 adds LimSlipDiff option to the system got that too>?
symptoms for working are>......
1: lamp dead.
2: lever stuck
3: tires x4 missing torque to earth?
1999 WJ jeep
4 steering binds up.?

say what is there.
and say what not working means , exactly
and say what tires are touching, (pavement , ICE or dirt)
we cant guess, road, either.

Why can't my 2006 jeep go into 4 wheel drive?


are you on dirt? or pavement...????????????????????????
we cant answer until you answer what 4wd option you have.
if that makes no sense, then read the operators guide,
it tells you what's there and how to use it.
read that first, then ask questions,?
and if Part time 4wd?, it';s not to be used on dry pavement only ICE.

eg:

4WD: Select-Trac (or older Select-Drive has a slip coupling too, NP129/229) is AWD in that, "the "4Hi" setting the drive shafts were coupled together using a viscous-type coupler " this anti wind up slipper"
Watch out for exception 1: Select-Trac NP228 based jeeps, it does not have a viscous-type limited-slip coupling. It was used briefly in 1986.
Quada-Trac is full time 4WD (not in lock mode) has a real center differential to shift torque between front and rear. This is the best system , not just a slip clutch as above. Then went BACK to the slipper in 1980. (odd huh?) Up to 1998.
Quadra-Trac-II "4-All Time", "N" or neutral, and "4-Lo". In "4-All Time", torque is applied to the rear wheels under normal driving conditions.
If the rear axle starts rotating at a significantly higher rate than the front axle, hydraulic pressure builds up in the gerotor oil pump and causes the clutch pack, to progressively transfer torque to the front axle, until both axles return to the same speed
Quadra-Trac I was introduced in 2004-10, same as above but is automatic with no driver controls ,like above.
The Quadra-Drive system was introduced in 1999 and is based on the Quadra-Trac II system but adds limited slip differentials (the best full time system ,with great traction to all wheels all the time) 1999 to 04.
Quadra-Drive-II has electronic limited slip differentials or ELSDs 2005 up.

Why wont my jep go into 4 wheel drive when I pull th lever?


which system?
we cant guess what is In YOUR CAR, ever.
you must SAY. or RTM, in the glove box.
and why are you using 4wd on dry pavement, now>?

1999 jeep grand cherikee 4 wheel drive not working


You need to be more specific. To start, which 4 wheel drive system your jeep has? (Select Trac, Quadra Trac II or Quadra Drive)
Then: does it never work, or only in 4-Lo?

Quadra Trac II 4 wheel drive problem


Oil is added to transfer case through a plug usually located about half way up the back of the case.
When making a diagnosis, a good tech relies upon previous experience matching that to known symptoms, then upon teardown to verify his ideas. A good working knowledge is essential so the tech can picture in his mind what is happening inside the unit.(i once knew an old tech who could sit in the shop office and make a correct diagnosis as another tech drove a vehicle into the shop) That's rare, but there are good people out there! Your coupler may have to be removed, but that largely depends upon what the shop sees and feels.
Good luck

Turning sharply in parking lot vibration or rubbing feeling in the steering also in reverse on 2001 grande cherokee with quadra track 2


1st let me make sure I understand your Jeeps 4 wheel drive. I believe the quadra trac system is a full time 4 wheel drive, there is no 2 wheel drive setting, only a separate 4 Lo (for very slow speed). If this is correct, the problem is, the quadra trac system you have is supposed to compensate for any variations in wheel speed, whether it's driving in the snow, or cutting the wheels sharply to park on dry pavement. What u describe is typical behavior of a part time 4 wheel drive system. The problem is, your full time 4x4 should be compensating for this, and it's not. So, let me know if the above info about your 4wd is accurate (no part time 4wd setting, no 2wd setting, only full time 4wd and 4Lo setting. If it is, the system is not compensating for changes in the wheel slippage correctly.

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
