My rear end is leaking from where the driveshaft meets the differential housing, so I bought a new drive pinion seal, and before I go running head first into the job I would like to know if there is are any tricks or anything I should know before tackling it.


Do I need parts other than the drive pinion seal?

How do I pull the drive shaft out to get at the old seal?

Is this going to be a monumental job or should it be fairly easy and straight forward?

 

Umm think you need to pull the rear end apart to do this. I may be wrong though

 

why? Shouldn't I just be bale to remove the drive shaft, pull the seal and replace it all?

Even the parts list shows the seal as being pulled out from the "front" of the rear end.

Sorry about the different account, a long time ago I asked to have some accounts merged so I didnt have to use facebook to login, but no one ever did it.

 

Watching some YT videos and it looks pretty straight forward, but what I need to find out is what size the nut is that holds the yolk on.

 

pull the drive shaft. You will need and impact to remove the yoke. Use a seal puller to remove the old seal. Lube the new seal with gear oil. Check threads on here not sure the torque for the yoke and drive shaft bolts. Its super easy defintley a DIY item.

 

Uhm------BEFORE YOU START MOVING ANYTHING, you need to mark the driveshaft to the yoke, the nut location on the pinion shaft. The preload is critical, but the only thing you need to do, is tighten the yoke down EXACTLY to the same position it was in when you removed it, or you get a new crush washer, and an expensive inch pound torque wrench and tighten it to the specs in the service manual. Its a simple job, but it has to be done right, or it will fail.

 

That's why I try to find some videos first, or I would have pulled that thing without marks.

I think I'll try and tackel this today if it doesn't rain.

 

got'er done. It wasn't too bad, and I feel confident that I didn't over tighten the main nut.

No more leaking finally..... my parking spot has a huge oil stain from diff. oil now though.

 

Great!
