I have a 9 bolt rear with what I think is a bad wheel bearing. The whining increases with speed and goes away when I make a lane change to the right. But right now that isn't my main concern with the mess. My rotors are rusted to the axles! I've tried all different types of rust penetrant and even a mid sized hammer will take chunks out of the rotor. Not to mention flatenig some threads on the studs. These things are NOT moving.

So I guess my question is something like... is there any other way of getting the axles out of the housing? I don't really want to drill through the rotors to try and reach the bearing retainer bolts. Are those 'T' bolts easy to find and replace?

In the mean time I am looking for someone who has an oxy fuel torch to heat up the rotors.

 

well i have never been in a 9bolt, i assume it has c-clip axels, if so, take off the back cover, rotate the carrier until you can see screw that realeases the retaining pin, remove the screw, the slip big retaining pin (goes right now the center of the carrier) when that is out, you can push the axle IN, it will move 1/4" or so, once it is pushed in, pull the C-clip off the axel, then the whole axel will slide out.

hope that helps.

 

Nope.. no c-clips. It comes with non c-clips axles and the axle bearing hold them in on their own. There are 4 bolts at the end of the housing that hold in the bearing retainer and brake backing plate. Those have to come out to get the axles out, with the help of a slide hammer.

 

well in that case i am not going to be much help

 

yep I had to heat up mine. I did not care about the rotors because I was putting my larger ones on it so I fuged up the rotors real good and they did not budge till the hot wrench hit them.

 

So... are we talking red hot or something a little less intimidating? The rotors are still in great shape (probably because the calipers don't work too well) so I would like to salvage them if possible. That wasn't a propane torch was it?

How is this one for a long shot of a question... you wouldn't happen to remember the size of the nuts on the bearing retainers, do you?

 

For those searching, it is a tank of MAPP gas. Make sure your nozzle works with it since not all the propane ones work for both gasses. It took about half an hour of heating per rotor plus some beating with the hammer.

 

Borrow or rent a real torch with Oxygen/Acetyline gas. It would make it much easier... Careful though things heat up quick!
