Why does it continue to leak?


Elisa where ? are you working at, EXACTLY?
sounds like it's wheel /axle bearing, is it?
or the pinion bearing????? there are many bearings in any axle.

id bet $100 you didnt just pop in a new rear crankshaft bearing
as other poster guessed.

my guess is the rear axle seal leaked, GL5 lube
and soaked the brakes and all? or the front pinion?
the job requires, all Gear lube, be cleaning off all parts there.
after the job ends, or it will leak RESIDUAL GL5 (imagine a kitchen sponge?)
which axle , the 198RBI or the 226RBA??

this seal., must i guess?
so if this seal leaks, its because the bearing is bad, and beat the seal to deathh.
#1 cause.
when it leaks goes all over.
the rear has discs but has TopHAT, emrg. brake shoes
and those will be wrecked, (soaked in GL5 lube and leak after
and the shoes are wrecked too.) so did you clean all that and replace all that. (i can guess what you did or touched,)

How do i change rear pinion seal on 2007 grand gherokee


This is not really a job for a novice. You will have to remove the rear drive shaft from the pinion, remove the pinion nut and the pinion itself, then remove the seal and replace with a new one. The tricky part is getting the pinion replaces and getting the correct torque setting without changing the pinion depth and compressing the crush sleeve more than spec.

So about anything even close to or more than

Differential gasket


Rear cover gasket is easy. Unbolt, drain, clean and replace gasket; fill with proper gear oil. Pinion seal on the front of the differential, different matter. If its the pinion seal leaking, take it to a shop with experienced techs.

I have developed a roar from the driver side rear of my 2004 Jeep Grand Cherokee. I suspect it is the rear wheel bearing. Is it easy to replace? I have done it on Ford truck before. It has 80000 miles on...


YEP CHRYSLER, FORD, CHEVROLET REPLACING REAR WHEEL AXLESHAFT SEAL AND BEARING.YOU HAVE TO REMOVE DIFFERENTIAL COVER DRAIN FLUID REMOVE LOCK BOLT SECURING PINION SHAFT HOLD PINION GEARS IN AND REMOVE C LOCK FROM INNER END OF THE AXLESHAFT. BASICALLY FORD AND CHRYSLER DIFFERERENTIAL ABOUT THE SAME YOU SHOULD HAVE NO PROBLEM FIXING WHEEL BEARING.

Fluid leakage


Leak at the front is likely from the c/v joint, Either the strap is loose or the boot is split. Replacement is nearly the same exact job as replacing the axle itself and generally the price of a rebuilt or scrapyard axle is worth the $.
Leak at the rear sounds like a pinion seal. Though it is easy to do that job, if you don't do it correctly you will change the pinion gear depth and that can cause the differential to fail. I recommend you get a haynes or chilton manual to do this work or have a competent shop do it for you.
If the rear leak isn't terrible, often you can add lucas additive to the diff lube and just keep an eye on it so it doesn't run low. (check level at the plug in the rear cover).
Any problems or other questions, just ask!!

Rear diff problem


The only place you did not mention is the pinion seal (at the yoke where the driveshaft connects) Any leak from a differential should be fairly obvious...clean everything off well and drive it, You should see seepage somewhere. Any grease on the wheels or new fluid where you cleaned will tell you where to look. If it is at the pinion seal, If you haven't done this before, don't...you can disturb the adjustment inside the gear case and damage the gears.

Pinion seal leaking


check your rear diff vent if pluged clean it out and clean up the pinion seal.sometimes if the leak is caused by pluged vent and has not been leaking long once vent is clean sometimes the leak will stop.there is not a specific torque amount because it is rotational torque(how hard to turn pinion).there is a crush sleve on the pinion and if torqued too tight or too loose brg preload will be wrong and brg damage could result.mark and remove drive shaft.remove rear wheels,brakes,axles.so when turning pinion you dont have any drag from brakes or axles.mark the position of the yoke on the pinion.remove yoke,replace seal,reinstall yoke be sure to replace pinion nut.tighten nut until it takes the exact same amount of force to turn pinion as before taking original pinion nut off.hope this helps.
