There has been some concerns about the rear stabilizer bar mounts cracking, check that. You don't need to have it on a rack just take the jack one side at a time, remove the wheel, and check the top rear brackets for cracked welds. Doesn't matter which side you do first unless you think it is making the noise on one side or the other. Do the side you think it might be first. If you find the weld cracked, don't stop there, do the other side and make sure it is OK. Good luck!
