Does it shake all the time or just when accelerating?
it shakes really bad around 30 to 35 and the it smoothes out i have changed the universal joints and the swing bearing
Ok, only when accelerating?
OK, did you throw a weight?
what is that
weight on the drive shaft to balance it?
i dont know
If all the u-joints are good, then it could be something in the diff.Do you have a set of jack stands?
Ok, and it is 2wd, so suport the rear end with the jack stands and run the engine with transmission in gear and watch the drive shaft.
and then what
Watch the way it rotates, it should spin smooth, see if the shaft is jumping up and down.
just be sure the front wheels are blocked.
if its jumping what should i change
WEll, it could be the shaft that is bent or something still is bad with the u-joints.
could it be in my rear end
not as likely or it would make the vibration all the time or worse when faster.
ok thanks so it could be my u joints or my driveshaft
It could be, do the test and see. If they do jump, then take it off and take it to a driveshaft shop.
