Completed this on Sunday. First off let me start by complaining about what an absurd design this is. Why can't the axle shaft just be one piece like every other car?

Anyways....
The stub remained in the trans after I pulled the axle. I removed c ring and devised a rig of 3 crowbars. 2 to grasp the c ring slit on the shaft and the 3rd facing the opposite way to hammer on. $30 of that and 30 minutes of trying and it was a complete fail. I then just took the prybar and pried it out. It came out instantly with no effort...sigh.
I removed the old cup portion from the stub shaft using a Harbor Freight Pittman arm puller. I used the puller to install it as well. I had 4 pairs of snap ring pliers, none of which were correct for this. A $1 harbor freight pick tool set also worked well as a substitute for the rings. The seal itself came out with a few repeated attempts around the circumference with a standard seal puller.

Jobs done, seals replaced, there are expensive specialty tools from Kent-Moore , but ingenuity provides a method to get the job done.

 

I need to replace my CV axles and I might need to get new "nubs" as they were referred to in this post. My mechanic doesn't want to have to disassemble and reuse the old nubs.

I assume this is the "nub" i would need but i really dont want to spend another $200 if i dont have to

I have some experiance working on cars but I usually steer clear of transmission stuff. Is this something that I could do on my own? Will I need any snap rings or O rings?

 

Replaced my cv axles last week, the nub stayed in the transmission case, easy job! Took 30 to 45 minutes per side, in my driveway. While I had my hands dirty, I swapped seals

I used two of the kits from SKF 16148

 

You "mechanic" needs an education. Did you notice the price? And he will mark it up for a profit. It only takes a bearing separator that is in the bottom of most tool boxes. Only the passenger side comes out with the axle.

Find a new mechanic. He would rather spend your $100 than do 2 minutes of work.

 

You have a point. My mechanic isn't dumb by any means and I fully trust what he says. His son is the one who told me that so ill try to get a hold of my actual mechanic and see what he says. Dos the axel shaft have to be replaced when doing this? I just had them replaced a month ago (probably due to the bad cv axles)

 

Axle shaft = CV axle

 

To replace the seals then the cv axles must be removed then reinstalled, but not replaced. Why didn’t your mechanic replace the seals then ? And is it possible he nicked the seals installing the new cv axles

It is fairly easy to replace the seals, here’s a how to from you tube

 

You definitely need a new mechanic. And now you paid him to half-do a job that you're going to attempt to re-do yourself anyway? I'm really confused. Anyways, as stated above it's not that bad, however I wouldn't recommend it if you've never replaced an axle before.

 

nah nah. The axel shaft seals were bad when i bought the car 2 years ago (i only just replaced them about 2 months ago). About a week ago my cv axles started to shudder under acceleration again (separate post that oldblue helped me with). The 3/4" transmission mount spacer i installed (after lowering the car 2" with coilovers) helped for a month but now the shudder is back. I honestly think my cv axles have been bad for a while but my suspension is now too stiff to absorb the shudder (thus causing the bad seals when I bought it). I provide all of my own parts (I either use my discount at advanced auto or i order from Rock Auto). I definitly should have provided more info earlier. Currently the axel shaft seals are not leaking (I have been checking on them every couple weeks) so I won't need to replace them when I do the axels. I might be able to rent a bearing separator for the left side nub. I would obviously prefer to do this myself and learn but I always get nervous doing anything close to the transmission.
