I am replacing the seal on the rear penion i need touqe specs on the nut


PINION FLANGE & OIL SEAL

CAUTION: Following procedure must be used to retain proper pinion bearing preload. Failure to follow procedure may result in premature axle assembly or component failure. Ensure pinion bearing preload is checked before disassembly, as previous pinion bearing preload will be used during reassembly.

Removal

1. Raise and support vehicle. Scribe reference mark on drive shaft-to-pinion flange on differential for reassembly reference. Remove bolts and "U" joint straps at pinion flange on differential.
Disconnect drive shaft from differential.
2. Remove rear wheels and brake drums to prevent any drag that may affect pinion bearing preload reading. Using INCH-lb. torque wrench, measure amount of force required to rotate pinion. This is pinion bearing preload. Record pinion bearing preload for reassembly reference.
3. Using Holder (6719), hold pinion flange. Remove pinion nut and washer. Scribe reference mark on pinion flange-to-pinion for reassembly reference. Using appropriate puller, remove pinion flange from pinion. Remove oil seal from axle housing.

Installation

1. Ensure oil seal surface in axle housing is clean. Coat lip of oil seal with gear lube. Install oil seal using appropriate seal installer. Drive oil seal into axle housing until oil seal installer contacts axle housing.
2. Install pinion flange on pinion with reference mark aligned. Using appropriate pinion flange installer, install pinion flange on pinion.

CAUTION: Washer must be installed on pinion with convex side of washer facing outward (away from pinion).

3. Install washer on pinion with convex side of washer facing outward (away from pinion). Install NEW pinion nut. Tighten pinion nut to 210 ft. lbs. (285 N.m). Rotate pinion several times to seat pinion bearings.

CAUTION: DO NOT overtighten or loosen then retighten pinion nut when adjusting pinion bearing preload. If pinion nut is overtightened, collapsible spacer on pinion must be replaced.

4. Rotate pinion using INCH-lb. torque wrench. Rotating torque should be equal to reading recorded in removal step 2) , plus 5 INCH lbs. (.056 N.m). If rotating torque is low, tighten pinion nut in small increments until proper rotating torque is obtained.
5. To install remaining components, reverse removal procedure using NEW "U" joint straps and bolts. Ensure all reference marks are aligned. Tighten bolts to specification. Check lubricant level and add if necessary.

Rear axle noise. pinion bearing? do i need to reset pinion and ringgear if need to replace?


possibly bearings. but i wouldnt drive it till you check it out cause if its just the bearings you could possibly save the ring and pinion. it could be the ring and pinion and if it is you will need to either replace or rebuild the rear end.

Axcel rear noisy


Your carrier bearings and possibly the pinion bearings are the source if the noise is a low pitched grumble or gravelly noise that starts just about 20 mph and up. If it is louder when quickly changing lanes to the left, it is probably the right wheel bearing, and if it is louder when changing lanes to the right, it is the left wheel bearing. If it is a whine that is really annoying at 45-65 mph, your ring and pinion are probably worn beyond their design specification limit. If your U-joints are OK, but you can hear a loud clunk from the rear when you get on and off the throttle, you definitely have play in your ring and pinion. Have the cover removed and you can sheck this easily. I have worked on several Jeep Grand Cherokee differentials, and the ring an pinion has needed replacing on them all. A few had bad bearings, too. You should probably replace the bearings and the ring and pinion, because the labor is nearly the same and the parts are just a bit more. If you look through the forums on the www you will find many people that replaced the bearings to fix the grumble, only to finish the job and find out they also have the whine.
