Angry rear pinion seal

just had an oil change and i was told i needed a new rear pinion seal. is this something i can do on my own? after paying $75 for the oil change i don't feel like bringing it back to fix the rear pinion seal if it is something that i can do.

you have to adjust the ring and pinion after installing the rear pinion bearing.
my TJ is in the garage today and tomorrow morning becaus it also needs a new rear pinion bearing.

He's replacing the seal, not the pinion bearing. The job isn't difficult, I replaced mine in probably 45 minutes start to finish. Remove the pinion nut (takes a long breaker bar or an impact wrench, remove the seal, tap in a new seal, then torque the pinion nut down to 180 ft-lbs. or so. Removing the old seal is the most difficult part but it can be done by cutting it so it can be pulled apart with pliers where vise grips can really help grip and tear the old one apart and out... assuming you don't have a seal puller of course. Chicago Rawhide is an excellent seal brand to install if you can find one, they're very rugged and less likely to be damaged during the install process. Remember to pack the back side of the seal with grease and tap it in gently and evenly all the way around until it seats. It can be frustrating to get it seated since it wants to cock to one side or the other before it gets started so just take your time.

does 180ft/lbs work fine for the d30?

I don't know if that'd work with the D30 that has a crush sleeve, I'd be wary.

the d35 has a crush sleeve too and that should be fine as it takes 300-400 foot pounds to crush the sleeve any more and change the preload. I would say 100 to 150

NOTES
(1) Torque pinion nut until all end-play is removed and the minimum wrench torque is achieved. Check torque to
rotate of pinion with inch-lb (N.m) torque wrench for proper rotating torque. See Specification for proper pinion
bearing preload. Continue to tighten in small increments until the proper rotating torque is achieved. Measure
the preload torque frequently to avoid overtightening of the pinion nut. CAUTION: IF PRELOAD TORQUE IS
EXCEEDED, A NEW COLLAPSIBLE SPACER MUST BE INSTALLED AND THE TORQUE SEQUENCE
REPEATED.
(2) Pinion bearing preload is controlled by increasing or reducing the amount of solid shims. For service, one
should torque the pinion nut to the mid-range of the wrench torque specification.

Thats for setting preload he doesn't need to do that as the sleeve is allready crushed.

Yeah I just thought it was some good info and even thought the sleeve is compressed allready he will still need to go to the lowest torque with in the specs and that would be 160ft-lbs

ya dana 30 and 35 has crush sleeves. if you have good strong air, and impact you can rap it goodentight. they say don't reuse the pinion nut, get a new one. i always get by w/ using some blue threadlocker, and tightening the original nut w/ impact gun. but if you have a wimpy compressor and gun it might not be tight enough

the preload is already set on the bearing, so you don't want to change it, but it needs to be tight enough to retain that preload, and not vibrate, or work loose. you can do it yourself. usually you can take a small chisel, and hit the very edge of the seal in all around and it comes out easy. i only say that cuz an inexpereinced person could damage sealing surfaces with seal pullers, pliers, or screwdrivers.

good luck
