I have searched for this on here, but no luck so here goes...

So I noticed a new sound this past week now that I have been driving the XJ again (due to snow).

I am getting a low vib/burp/growl when I get off the gas at highway speeds (IE greater then 55 mph). Once the slows to 55 or lower I don't hear it. It really does sounds like a low rumble or burp.

I am thinking that it might be due to not having at TC drop or SYE, but I'm looking for other possible causes. U-joint going maybe?

Oh, and please lets not let this degrade into the TC drop VS. SYE battles... LOL

Stats are in sig...

Thanks!

 

What... no one has an idea...

Come on, don't make me have to through my self to JeepForum....

 

Well figured it out... Or, I think I located the problems... Pinion bearing up front is shot as well as the front drive shaft slip is shot. I figure that one of them is the culprit for the sound.

Shall see once I get them replaced.
