I need to remove the axles to install a brake kit. Following instructions, says to remove pin and spider gears. Did that. Now remove C-Clips?uzzled: What... these appear to be pressed fit gears? HELP PLEASEray: What do I need to do? Also, does this mean the gears have been replaced with something (not stock)?
Jack, you really need to buy a chassis service manual. In the meantime, it's here for reference: http://boattail-riviera-by-buick.com/library/documents/1972 buick chassis sm/index.html There is a hole drilled in the axle flange between two of the lugs. The hole is there to give you access to the four retaining flange nuts that hold the axles in place. Once the four nuts are removed, the axles can be pulled out. If they're stubborn, put the drums on backwards and use them like a slide hammer with a few lug nuts also installed backwards. Be careful not to let the backing plates hang loose or you'll be replacing those brake lines, unless you were planning to anyway. Devon
Sounds like those directions are for a chevy... what rear end do you have? Devon's directions are for a Buick rear. If that is what you have then follow his post. If you are not sure go here: http://www.buickperformanceclub.com/ - Bill
Thank you, the instructions are for a general '72 A-Body, but theu suck really bad. I'll give the reverse drum trick a try. The rear end is off the Buick currently. ---------- Post added at 03:34 PM ---------- Previous post was at 03:22 PM ---------- They are not budging. How they heck would you ever get them back on? Going try another way.
First make sure you have the original Buick rear. For 72, that would be an 8.5 10 bolt with bolt in axles. Lots of things get changed in a 40 year old car. If you have the Buick rear, remove the 4 bolts and use the brake drum as a slide hammer as Devon suggested.
Yep... pulled the 4-bolts and did the reverse drum trick and they would not budge. Funny thing is I cut the drum plate off because I didn't need it and was worried what I was going to get into by pulling the axles. After it was done, I hit the lug studs with a hammer to remove them so I can replace with longer one and of course, the axle then came free. Oh well, we got it. Here are a couple of pics, we are done for the night, will do more tomorrow. Thanks guys for the help! Here the rear is on our trash cars. Ok, so my son was not here at the time. I picked that rear up by myself and set it up on both of those trash cans. Redneck for sure! Here is where we are now
Lonnie, I tried to PM ya a few days ago and says your messages are full. PM a email if you don't mind.
And since you have the rear out....are you replacing the upper control arm bushings? Would be easy to do....BTW it looks good. Scott
Scott I was just about to post that, I think it's the same bushing you mentioned. The 2 bushings above the differential where probably the original. Very cracked and brittle. Although they didn't want to come out. I pulled them thinking my kit had them included, but it doesn't, so I'll have to pick up a pair. The rest of the bushing will be new. ---------- Post added at 09:26 PM ---------- Previous post was at 09:25 PM ---------- That and a new brake line that I cutou: Dumb noob mistake.
Stick a posi carrier and some 3:42 gears in it before you put it back in. Talk to Monzaz on the board.
I am hoping to have the rear put back on car today. May not happend, having trouble finding the 2 bushings at auto parts stores. Mark, thanks for the contact, I'll pm and see what he has for gears and posi.
Well worked on the rear until about 3pm. The wife said I had to leave car alone and take her out on date night. So didn't finished getting the rear back in. What we learned today is bolt on kit, doesn't just bolt on when the car is 40years old and a 1/4inch of dirt and oil caked on everything.
