Rear axle noise '02 GC
I have an '02 Jeep Grand Cherokee. It is the "Overland" edition with
the High Output 4.7 V-8 and Quadra Drive 4WD system.
I had the 60,000 mile service performed by my local jeep dealer just
600 miles back and in the last few days I've noticed a combination
grinding, groaning, and vibration coming from the rear axle when
turning tight turns at parking lot-speeds.
My owners manual calls for a "friction additive" to be added to the
front and rear axles since my vehicle is equipped with the Quadra
Drive 4WD system. My service records from the dealer state that they
serviced the axles with standard gear lube, no mention of any friction
additive.
Would the lack of a friction additive cause the problems that I'm
having and is permanent damage being done? (I believe the axles are
limited-slip on this model.)
Is it too late to add the friction additive now?
I'll be taking it back to the dealer on Monday and I want to know if
they screwed up and if I'm in for a fight.
Thanks,
Concerned in PA

Re: Rear axle noise '02 GC
It sounds like you are correct, that the friction modifier was not
installed.
What is happening is the VariTracs (part of QuadraDrive) are locking up
before they are supposed to.... the FM makes the lube slipperier to prevent
premature engagement.
You need to get the additive in there as soon as possible.
The extend of any damage depends on how often and hard the clutch packs have
engaged.
I wouldn't suggest driving it anywhere in the meantime to prevent any
further chance of damage, it would be best if the dealer were to send a
flat-bed wrecker to pick it up.
At the very least they should pick up the towing charge and correctly change
the lube with FM included this time. Be sure that they use the correct
lube.
There is the further question as to whether any damage to the clutch packs
was caused by their negligence, be sure that any paperwork clearly states
this 'repair' was necessitated by their mistake.
It may be worthwhile to consider offering to pay a portion of the
replacement clutch pack parts (parts only) while they pick up the balance of
the parts, labor, and, of course, the replacement lube and FM.
If you have the towing package then Synthetic 75w-140 is the required lube
(plus the FM additive).

Billy Ray,
Thanks for the info...I'm going to have them pick it up on Monday.
Its been about 6 weeks and 600 miles since the service. I only began
hearing the noises yesterday...but it is my wife's vehicle so I don't
drive it too often. Hopefully there hasn't been any damage.
