Hello. I have a 2004 Trailblazer w/95k miles. While driving I noticed what seems to be rear road noise (rumbling). Thinking it may be a tire problem I raised the rear of the vehicle only to fine slight play in the axels. There are no fluid leaks anywhere but I do have some slop when pushing/pulling on rear tires. I pulled the calipers off to verify what was moving was not loose wheels. Any suggestions on what I have here?
Thanks
