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. |

Does the pinion have preload? If you grab hold of the pinion flange and push up and down is it sloppy? A loose pinion is a guaranteed leaker.
Is there a groove worn on the seal journal surface of the flange? |

Is there a groove worn on the seal journal surface of the flange? Pinion is loaded. Has a brand new GM yoke in it. GM makes a kit with a yoke, seal, washer and nut. Its all in it. BTW, how hot is a rear supposed to get? Anyone ever put a temp gun on one after a drive? Just curious as I went for a test drive, about 10 miles and the rear was hot to the touch. |
