Rear end seals
Well the rear end on my 84 is leaking to the point that I need to fix it now. It is the stock D36 with 3.08 gears in it.
The drivers side seal is leaking pretty bad to the point that it is leaving 1-2" spots on the driveway.
I do not want to rebuild the whole rear end, but was wondering if I can remove the yokes on the sides and front and replace the outer seals without dissambeling the whole rear.
I know a guy that can rebuilt the rear for $400 but would rather just replace the seals.
Can I do that?

If I recall, you have to remove the entire diff, seperate it from the batwing cover, and remove the heavy duty C-clips inside to pull the yokes out for seal replacement.
And before you ask, there is no cover gasket, just RTV.

Yep, it's not difficult to change seals but the clips for the output shafts are indeed inside as CC stated. It's also advisable to consult the FSM for the proper procedure to R&R the input yoke. This is so you don't risk disturbing the pinion depth setting, as it is set with a crush sleeve.

If the $400 includes bearings and seals as well as setting the back lash correctly I would take it out and let him do it. I assume that is re-using your R&P. The 86 had snap rings that had to be removed to get the yokes out and let me tell you that was a PIA, very stout thick rings.

That the snap rings are stout. I gave up using my craftsman snap ring plier, after breaking 7 or 8 of the replacable tips.

Sorry guys I didnt clairify, this is with the rear out and seperated from the batwing. The main concern I have is if there is any spacing backlash etc I need to worry about.
If there are any "settings" that need to be done, then I dont want to risk it.
And yes the $400 is using the old ring and pinion. I would hope they are still good. The car has 117K miles so Im not sure but I did not want to change the ratio.

To the best of my knowledge pinion depth on all Dana 36 & 44 rear axles is set with shims, not a crush sleeve. Consult the FSM for your year to verify, then replace the seals as suggested above, install a new pinion nut and torque to specifications.
