PostPosted: Tue May 31, 2011 10:23 am    Post subject:  Help - Stuck Hub! Reply with quote

Over the weekend I tried to replace the right front hub on my '04 Impala. I did the left front about 6 months ago, and it went pretty smoothly. This time however, I can't get the old hub to come off the axle spindle. I soaked it with PB Blaster, and smacked it with several different hammers. I saw on another thread where somebody suggested using an air chisel. Where would I use the chisel? On the very end of the axel?

Thanks for any help!

I don't think I'd use an air chisel on the axle unless you wanted to replace the axle as well. Any chance a hub puller might get it off?

Air chisel is used on the inside of the hub (the back part that faces the opposite wheel). Work the chisel around in a circle a couple of times and it should loosen it enough to pull off or smack off with a hammer. It will come off...just need the right amount of elbow grease and patience. Good luck.

Not sure if the fronts are the same as the rears in terms of how they're mounted to the upright, but when I changed my rear hub it was well stuck into the upright. I borrowed a very large slide hammer hub/axle puller from my local Advance Auto and it came right out after 2-3 pulls.

If I understand the problem, the half shaft splines are seized in the hub.
If so the gm tool is J 42129.
A gear puller should also work. Hook the 3 gear puller arms to the wheel stud flange and the gear puller screw to the end of the half shaft. Crank the screw, somethings gonna give!
If the problem is the hub is seized to the steering knuckle...oops, disregard this post.

The little divit on the front of the half shaft is made so the pointy attachment of the air hammer can be used.

Back in April when we replace the wheel hubs on my Impala also an 04, the passanger hub had fused itself to the CV splines. I took it to a buddies shop and we had the press at 30 tons and it still was not popping loose even after we applied heat to the hub. I ended up throwing the hub, shaft and knuckle in his scrap metal bin and just bought a new knuckle and CV shaft. We had actually tried a gear puller at the house before resorting to the press at his shop.

Yup, when they don;t come off just put the chizel on and go to town between the knuckle and the hub. That or put it on the back of the where the rotor sits...try it that way. But when the bearings are bad like that I've had a couple where only the spindle comes out.
