Sounds like a uj dose the noise go away when you take your foot off the gas and roll along????? Mine dose (well its not mine its the basement birds) and now I got a uj to change this week. If its the anything else get a new axel off of e-bay its easier than doing the innner rear wheel bearings.Oh no I'm starting to sound like a zook gook....must get out of the basement. Help,help, help.
