I had to pull my rear hubs . I went to remove the long side first, using a three foot puller . The hub would not budge . I heated it up using my torch , no go . I tried the short side ,same thing . ended up tacking the brakes apart , and removing the 6 bolts holding the backing plate ,and pulling the whole axle ,bearing ,backing plate ,shims, gaskets ,hubs . use my press to get the hubs separated from the axle . had to do both sides the same way . Thing is I just had the rear end apart a couple of months ago . put a locker in it . this time i was taking the locker out . I actually distorted the wheel hub with the puller , and one of the studs sheared off ,trying to get the hub off . Never in my 20 years have I ever had this problem getting the rear hub off the tapered axle . I have ordered new hubs. I have cleaned the tapered axle shaft up with some sanding cloth , Should I use never seize , on the new hubs ,i might have to get in this rear again , I don't want this to happen again .
that's the same puller that I used to remove my hubs . But it didn't work ,even after heating up the hubs . I had so much pressure on them I distorted both hubs .even broke a stud on one . I've removed hubs many times before ,but never had this issue . Do I need to use Never Seize ? has anyone else had this problem ?
As a rule a frozen hub is generally the result of:
1 - improper torque on the retaining nut resulting in an over-torqued issue or under-torque resulting in looseness that promotes the development of corrosion deposit buildup resulting in locking of the hub to the tapered shaft.
2 - lack of proper cleaning of the two surfaces of the tapered shaft end and the tapered hub opening leaving loose corroded layers to fuse together and to lock the hub up.
I would ask you 2 questions.
1 - Did you thoroughly clean and remove all corrosion residue from the shaft & hub before assembly?
2 - To what torque spec did you secure the hub nut?
yes I did clean the tapered axle area . I clean out the Key way ,threads ,and use some crocus cloth . I might have over tighten the Nut . I use the impact gun , I don't remember if I put the torque wrench on it or not . I just had assembled the rear end for a run on Sept 9, and a show on sept 11 . Everything was new , so the only possibility was over tightening. Thanks for your help
