Thanks for all the replies, based on how much grease was still on the axle on sunday, I am going to try the clean, regrease and re boot the current axle, I think I have caught it early enough that it should still be ok. In review of the the mecatech instrucstions, it appears getting to the axle is not all that bad, jack up vehicle on stands, use jack to relieve pressure on lower arm, undo 4 bolts, move back hub assembly a little and Walla', direct access to the axle. What about an alignment, is that required after this work? I have not seen in mentioned in other post, hmmmm... I plan on doing the above this weekend, I will provide a f/u when patient is in recovery.
