Great info! Any more specifics you think I need would be well recieved. I think I will go for it this weekend, the noise is driving me crazy! I either need a louder radio or to fix this! I checked it for heat after running it on the highway, and the pinion bearing feels like the culprit. It was not so hot you couldn't touch it, but fairly hot there. Obviously I will change all the bearings. Do I need to replace the crush sleeve in the pinion or can I reuse that? Are bearings and seals all I need to buy?
