Differential Questions

[YJTino]

Hi Guys, I have few quetions for you. I have oil all over the bottom of my rear differential. My friend talk to me about something blue in a tube that he used a long time ago for a gasket job. Do I have option for the gasket or it's standard? What kind of lube I need to use? My Haynes book is talking about limited slip??? and some extra product I need to put in it in addition to the regular lube. There a bunch of number on the diff. cap and would like to know what they mean? There a 35C top left. (52068832) (4-11) (5661-2) can be read on the tag attatched to the cover and (43225) (321 3) (rev-f) (09 25 91) DANA at the bottom. I can figure out the date and the gear ratio(4-11) but don't know about the rest :? Is there anything I should check since I'm in there? tanks a lot for the help like always

if there is no "LS" on the tag.. then don't worry about limited slip fluid... just get some standard gear oil an fill it up... as far as gasket.. get some permatex RTV gasket maker.. you're all set

I don't think a limited slip was ever available in the 2.5L YJ, but jeep has proved me wrong in the past

Just get some RTV to reseal the diff cover after you remove it and clean it up. The fluid could also be coming from the pinion seal, which is harder to replace, or further upstream like the transfer case output seal. Both the pinion seal and the transfer case output seal are a more common leak than the diff cover.

Dana 35 (C-clip), 4:10 gears. The rest is swahili to me as well.

There are aftermarket gaskets available (so I am told), but using RTV is the way it came from the factory and the way most do it.

Just clean her out real good and make sure you don't get any dirt in there!

most ready made gaskets will leak anyway

If you use any of the top synthetic 75-90 lubes (Mobil1, Royal Purple, Red Line....) the additive is included. I think out of all of the times I've replaced that cover gasket they've leaked 1/2 of the times.

You'r right, :shock: I think I have a bad pinion seal. How complicate is it to replace? In my book, it look like I have to remove the driveshaft to get to that seal. this seem fairly simple but I could be wrong. Do I need special tools or any tips on a project like this?
Thanks for the previous inputs. I'm going to buy the lube and the gasket sealant right now and probably check for the pinion seal too :| .

Sorry to doubt in your expertise but is it really 4:10 and not 4:11 gear ratio.

4.10, 4.11, whatever it takes :lol:

Although technically they may be 4.11, they are pretty commonly called 4.10's

There's a special procedure for replacing the pinion seal, you have to do it right or risk ruining the crush sleeve and throwing the ring and pinion tolerances off.

Thanks Bounty, Now I'm scare Should I attempt to do it or leave it to a mechanic. I'm ready for the challenge if you or someone else can guide me along the process. 8)

RE: Re: RE: Gettin

I tossed my old crush sleeve and put a new one on. Cranked the air gun up to 300 (probalbly more like 250 to 280) and cranked down the pinion nut 6 months ago. Havent had any problems. Just took off my diffrential cover yesterday to get all the water out from a minor lake incedent. Ring and pinion are fine.
