Re: Leaking Rear Differential Seal?

If I were you, I wouldn't do this job myself because although it is pretty simple, if you use an impact wrench on the pinon nut, you risk destroying the pinon bearing. I did this job on my mom's '04 Explorer last summer and I couldn't get enough torque on the nut by hand (when you're under the car, even with a 2 foot long breaker bar, you're not going to have enough leverage to budge the pinon nut), so I used my impact wrench. I made sure that I recorded the number of turns and everything so that the preload wouldn't change when I reassembled, but I ended up replacing the whole front diff with a used one because the pinion bearing ground itself into bits. If you had a lift where you could use your whole body weight to loosen/tighten the pinion nut by hand, I would say go for it, but if not then I highly recommend that you have a competent shop do it.

Re: Leaking Rear Differential Seal?

Its not a hard job and you can do the job in your driveway, but the biggest PITA is small space you have to work with to be able to make the 210lbs of torque. Find a local garage and pay the hour of labor it will take to change the seal.

Re: Leaking Rear Differential Seal?

Mine was leaking too..... really just weaping not a dripping yet but my GC was due for the 30k service plugs, fluids in diffs etc.... That portion of the bill for fluid and seal replacement in rear diff was 105.00. Work was done by a local Indy shop.

As others have suggested some things are worth paying for IMO.....

Re: Leaking Rear Differential Seal?

Thanks for the help and responses, esp Robpp. I got it fixed at the local Jeep dealer, only cost me $144. I called for a quote and they said one hour labor plus parts, I was shocked it was so cheap.
