inner seal rear axle removal

Post by Barteldes » Sun Dec 29, 2024 1:15 pm

234 Coupe
replacing the inner seal and im having a hard time getting it to come to me. ive tried wire, stiffer wire, my sturdy hook isnt long enough. tried a slim jim and i cant pull it hard enough.... i need something to hook it and is capable of being banged on toward me.....
and why would it be stuck in the first place? its hard to see but i think its the neoprene newer version not felt. . (like the replacement i bought)
thoughts?

One needs to remove the bearing sleeve before attempting to remove the seal.

Doesn't the bearing sleeve need to be removed before the inner seal can be removed?

The first step is to remove the Hyatt bearing sleeve. The seal is placed behind it, so once the sleeve is out, use hook tools, long coat hanger or welding rod with a sharp hooked end and pull away the seal.

These pics from the forum by Erick Bruckner shows using a long sheet rock type screw to drill into the seal. In his case the seal was the old leather and metal flange washer type. Once affixed, pull on the screw to remove the seal. Likely could work on the modern neoprene too by screwing into the rubber and metal backing.

Once had to pull a modern seal out, it was a tanged mess, as the previous owner just pushed it in over the Hyatt bearing sleeve, and it never seated. :shock:

Hopefully the previous owner did not use something like JB weld to keep it in place. Do you have anything long enough you can try to push it out from the other end of the axle?

Hi Bill,
How about using a piece of exhaust tubing a little bigger than the axle to drive the center of the seal in to make it cone shaped, breaking it
loose & giving you a better lip to get ahold of?

Could be the previous owner used silicon or hardening type Permatex to glue it in. I put the new style in dry, the neoprene covering should seal against the ring on the inboard side and sleeve holds it tight in place.
I know the voices aren't real but damn they have some good ideas! :shock:

Don't make this mistake I made. After reading a few posts and taking out the roller bearing and the liner from my rear axle I saw what I thought was the remnant of an inner seal. It was covered in grease. Pulling with a hook on the end of sturdy wire didn't budge it. I made a tool out of 1/8" flat stock with a handle I could hammer on ... it still wouldn't come out and my tool kept slipping off. By this time I had pulled out a lot of the grease and I noticed some bumps on the inner part of what I thought was a seal. See the pictures. Next I measured from the what I thought was a seal (but is really the end of the axle) to the outside of the bearing housing and got a just over 4". The new bearing sleeve was exactly 4" and the metal part of the new neoprene seal about 1/16" if that. So I cleaned out the rest of the old grease, slid the new seal in and installed the new sleeve as per the video. Everything went all the way in and was flush to the end of the bearing housing. I hope this post saves someone a lot of time that I wasted.
