There are special tools or tool mechanics need to remove, and replace wheel bearings on jaguars.
Need both sides, rear wheel Bearings replaced. on 2003 Jaguar XJ8
The book time to replace both rear wheel bearings is 5.8 hrs and this repair should probably be done by a mechanic due to the tools and knowledge needed to replace these bearings without damaging the rear axle.
I see quite a few Napa Auto care centers in your area http://www.napaautocare.com/ They have ASE certified mechanics and use the best parts.
Yes, I know it needs to be done by a mechanic. ;-) That is why I'm looking for one that has the appropriate tools necessary to this vehicle. They are specific tools for this model Jaguar - for what I am told by other mechanics who can't work on them b/c of the tools.
