Since the 3000 mile whipping the car got on the Power Tour and the optima Faceoff the rear end sounds like a cement mixer.
What is my best option? I haven't torn into the rear end to inspect but will next week. With the miles I am afraid the axles are shot, I don't think its a good idea to use "axle saver" bearings as they move the bearings inboard and stress the axle face more. Rebuild bearing/seal kits are around $200. The gears with those miles should be ok, would you change them? Thanks in advance. |

I put a temp gun on the yoke and the pumpkin after a spirited drive, 170 degrees.
I took it back apart and the new GM Yoke had a speedy sleeve looking deal with an oversize seal. So I took it off, used and old(new) seal with grey silicone on the back and pit it back together. Test drove it and is back on the rack, dry at the moment but seems to have to sit a while to show the leak. (IMG:http://i1122.photobucket.com/albums/l528/FASTFATBOY1/yoke.jpg) |

It is fixed as of now, I put the RTV on the washer to seal off the splines. Time will tell, only driven it 30 miles or so as I discovered a leaking brake line and parts are on the way. |
