Suggestion

Once the cv joint it out, you can pry out each stub (it's just held in with a snap ring) and replace the seals.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Yes i did a forum search but I could find these specific answers I just changed out the fluid...noticed the leak after If I remove the splines on the drivers side and pull the seal (where the leak is) do I have to remove the new fluid to do this? Ugh if so I want to leave the differential in...so if I unbolt the six bolts from the drive shaft...slide the drive shaft back (i am changing the shocks and springs now so I can do this); will i have room to pull out the splines, remove the seal, and put in a new seal??? How tight is that fit do I need to hammer it in? Any advice here? Now is the time I can do this since the suspension is out....Just need any tricks as well if you know of any thanks

POST 2Original post

You can't just undo the 6 bolts at the flange and drop the half shafts. You need to break the lower ball joint loose to get enough space to get the cv joint out of the stub. Once the cv joint it out, you can pry out each stub (it's just held in with a snap ring) and replace the seals. There should be very little oil leakage when changing output seals. Since you are changing struts, this is the perfect time to replace the seals. That is when I replaced mine.

POST 3 / ORIGINAL POSTEROriginal post

Quotes source post: 11564032

yes i know, but above I mention my springs and shocks are out so I have slack to move the drive shafts out around 6-7 inches giving me what I assume is enough room to pry out the spline shafts....i undid the drop links and with the struts/spring out i can drop the wheel carrier down to give me this slack.... My question is, the seals are tight....so is there enough room to put and pound/push the new seals in without having to drop the differential???? Is there a tool I can use to push them in? Thanks for the help

POST 4Original post

There is plenty of room. I replaced mine with diff in the car.
