Is it s scrape/squeak that gets faster as you back up faster?

 

no it dont scrape it Squeaks

 

My friend's truck had the same thing and only in reverse. He backed up and I listened from both sides of the truck and it wasn't clearly one side or the other. We doused the u-joints at the rear end and tranny with wd-40 and that fixed it. It has not done it since and he stopped at the dealer and the joints checked out fine. We had a lot of rain lately and his driveway holds water right under his truck and we assume that might be what caused it. Hope it works for you.....if it's clearly one side it might be brakes.

 

ya thats what im going to do tomorrow in the morning,what did you use to spray it with,and why do you think it would only do it in reverse
thanks again Craig

 

We started with wd-40 so it would penetrate to try and locate it but hasn't needed any thing since. Not sure why reverse only did it. Maybe it just pivots it a little different.

 

My old ranger did that...bad u joints
