Hey guy's, Can anyone tell me how to get the rear spendals off of my '76 short of using a cutting torch. I have everything loose on both sides, but no joy as to it comming off. I thought someone out there may have had this problem before and could tell me some way to break them loose. I have soaked them in penetrating oil, beat them with a hammer and a bigger hammer, have used several different configureations of pullers and presses with no joy. It has gotten to the point of possible nitro extraction method. If you can help I would really appreaciate it alot.

you probaly don't want to hear this but i cut my bearings out with a cutting torch it is not a fun job. they make special tools for this process. but you could always send it out and have it rebuilt. i also made a setup tool out of a old spindle to get the clearance right the first time. the clearance is the big thing you dont want to do it again.
Once they are out..............save yourself a lot of aggravation and setup your new bearings as a slip fit instead of a press fit.
All you need to do is take some emery paper available in long strips and sand down the spindles where the bearings sit so they will just barely slip on. Put the spindle in a vise with the lugs down (protect the lugs) in the vise jaw, be careful and then it is very convenient to pull the emery strip to take the surface down. It doesn't take much but is very effective. Work all around the shaft to take material off evenly. Don't take it all off from one side.
Then you can pre-assemble your bearings and spacer and get the right combination in there with the nut torqued down. It is nice to have a good selection of spacers to get the right end play. If you ever end up with a bearing problem in a little place in the boondocks, you can get the assembly apart easily. If you go the press on bearing route, well you are going to be stuck really stuck.
This is a good setup if you wish to repack your bearings every ten years or so, of course depending on your mileage.
I would suggest removing the bearing assembly and taking it to a machine shop for removal. You stand a real good chance of destroying your spindles if you are trying to beat them out with a hammer. You could also send the assemblys to one of several supporting vendors for a proper rebuild or exchange. If you don't have the right setup tools that's probably the best way to go.
Press or spindle knocker with mini-sledge. I knocked mine out with 10 to 20 whacks. The other side took about 50 whacks becauce I could not back off the brake shoes.
