hey, iv noticed that when im in revers, i here this sqeeking noise. i had my dad walk aside the truck to listen while i backed up, and i was riding the brake to amplify the noise, he could only make out that it was commin from the back end some where.

is this a possible bad u joint?

also the truck seems to vibrate slightly at like 30mph, and keeps shaking slightly all the way to 55mph, at about 65 it fades away and then comes back around 75mph.

any thoughts?


thanks,

Brian.

 

Sounds like a u-joint to me.
