W211 E63 09 Differential Quaife Upgrade & Pinion Repair
New to forum, not new to the car.
After 77,000 miles of bliss and a failing pinion bearing I am repairing the diff and upgrading with a Quaife. I may DIY this deal, but before I do this does anyone in Southern California already know who is qualified and good to work with? I plan to update my progress for others with the same diff (2113510608) : 2006-2009 W211 W219 E55 CLS55 E63 CLS63 AMG. I went to the dealer to order parts and the factory will not support rebuilding the differential with the sale of bearings, etc. They seem to want to run an expensive core swap program. First quote for the swap was $8500 installed without any upgrades.... I suppose they would wash the car too. Thus, the post and decision to buy a Quaife from Birds today. Updates to come. Suggestions welcome.
While not the same diff or car here is what I am contemplating.
On and off the car
