When ever i move the truck shakes and it sounds like its from the rear end i haven't time to take it apart but i don't know if its in my rear end or if i have just had a bad u-joint im just looking for some oppinions on what other people think before i start taking it appart
Well that sounds like you grenaded a rear end to me. You can crawl under the truck and look for play in the U-joints first by moving the driveshaft side to side and up and down at each end and you'll know right away if you broke one. If not, I'd bet on a rear end gone bad.
Some particulars on the truck would be nice.Ya know like year,engine tranny,2/4 WD.
You could have a bad u-joint,a dislodged brake pad,in the case of an auto tranny the flex plate may be broken.The posibilities are numerous.
I don't think think it looks like a harmonic balancer but the bearing is towards the front and the bearing seized and spun inside the rubber bushing it was held in. It was a very easy fix i did it on the floor in my garage.
