2010 XKR rear end squeak fixed. Took a long time to fix. Turned to be where the rear coil springs sit in the top nest or doughnut. The dealer replaced nearly everything including the struts before it was resolved. Quiet as a mouse for the last several months.

 

Cool! Occasionally mine creeks in the back. I'm suspecting the same thing.

 

Same here.

Convinced it was coming from the the RH upper wishbone which I changed but it turned out to be the coil spring isolator.

Exactly. On my 4th visit to the dealer, I was told I would not get my car back till they found and repaired the squeak. They did both sides just because. If our post will help just one person with a squeak I will be happy.

 

A liberal shot of WD40 and all was well?
