buddy of mine has a 2000 TJ with a d35 and the pinion seal is pissing oil

can we just remove the yoke and replace the seal or will removing the yoke mess up the back lash???

thanks

Remove the yoke, replace the seal, re-install the yoke at a 90* turn from previous location, torque down.

thanks man

whats the 90* rotation for? just curious

thanks

Yeah, really :confused:

Changing the seal was a once a year procedure for me with my old YJ, I think my driveline angles were a little steep, and was chewing up my seals... No biggie. I never had any trouble just slapping a new one in there *shrug*... But then again, maybe that's why I had to change them every year :confused: :D

Thanks Welby, we are going to change it out this weekend.

Rumor has it, thats your real pic

Any truth to this?

:D

BTW, Nice Quote!

Does'nt the warranty cover that?

my haynes manual has a bunch of crap about bearing preload checks before and after using torque wrench, and making sure you get it just right, and then if it isn't, you are supose to take it to a qualified mechanic (not very easy if you just screwed it up). That being said, I know plenty of people who have done the above without a problem... my's been leaking for the last year, but I decided the D35 ain't worth investing $0.35 in a seal, and I'm upgrading to 9" ford, but that's just me

I haven't changed mine except when doing my gears.... but I've been told marking the nut on the yoke is all that's required...

Sounds resonable.... :D

Actually, you want to change the nut - it's a lock-nut and make sure to torque it back to specs. The 90* rotation of the yoke is to "pre-load" the pinion gear. This according to a friend of mine at the Jeep dealership. I just did mine last weekend.

The proper way, according to Chrysler, is check the ttr (total torque to rotate) with a good dial type inch/lb. torque wrench, and add 5 inch lbs. when re-installing the new pinion nut. This assures a good stretch of the pinion on the crush sleeve.

Aw shit, there goes my newbie statis.

Replacing a pinion seal isn't too hard. I have done 3 on Dana 30's and 1 Dana 35. Just check the part of the yoke that comes in contact with the seal to make sure it is smooth and won't chew up the new seal. Other than that they are fairly easy to do.
