I have a 98 xj sport with a 3" lift. I was driving to work yesterday and noticed a strange noise from the rear passenger side. It sounds like a bad wheel bearing to me but the noise is only there between 50 and 60mph. When I let off the gas it completely goes away. I took the tire off and checked the bearing it all seems tight. It has all new breaks all the way around and new bearings up front. Any ideas on the problem here? It seemed strange it would stop as soon as I let off the gas

 

I forgot to mention this but the ujoints are all new and so are the tires if that helps at all. Thanks in advance

 

Muffler brackets.

When you are on the gas it vibrates harder.

Also check your T-case mount.

 

Well driving to work today and the noise is constant now. So wheel bearing is most likely the problem? Checked exhaust hangers all are tight. Transfer case mount is pretty bad so ill replace that. Any thoughts?

 

that mount may take care of it for ya. I know a lot of noise until i replaced mine.
