I have a Cobra replica built by a man of questionable competence and integrity. As, such I am having the car completely checked over by a local auto shop. The problem is that, while these folks are fine mechanics, they have no experience with the Jaguar XJ6 rear end. From what we have been able to determine thus far we have about 3/16" play in the right rear wheel hub and about 1/8" play in the left. Fourtunately the newly rebuilt engine spun a rod bearing before I could drive far enough to trash the wheel bearings. (That, of course, is a different story). We are aware that there are spacers/shims in the wheel hubs, but finding the proper size appears to be trial and error. Obviously, the bearings cannot be too tight or they will burn up, too loose and they will destroy themselves. What that "happy medium" is we have not quite figured out. The shims are manufactured in .002 increments and we are experimenting with different sizes to find the proper fit. If anyone knows what the proper clearance/play at the wheel hubs should be, that information would be greatly appreciated.
Thanks and keep the shiny side up!
