can somebody help?

My 03 Tacoma manual 4x4 has a bad vibration at speeds over 10mph. Replaced tires and amidships bearing and it got a little better but still shakes everything off my dash. Thinking its a joint problem but I need input before I spend the time and money

 

If the ujoints were vibrating that bad, he would have noticed it while replacing the bearing. With ujoints that bad, there will be slop in the driveline. Very shortly thereafter, there will be a driveshaft on the ground.

Check the driveshaft for missing weights, and proper phasing. Check your wheel bearings for slop.

 

have you hit your drive shaft on anything? you might have done it without even noticing it, any hard wheeling?

it might need to be re balanced. but just to make sure, you balanced your tired right? didnt just replace them?

 

Tires were balanced when installed. The truck has beenoff road maybe five times since the dealers lot. My father in law found an off road shop close by that assures me they know the problem. Gonna give them a shot. Will let you know

 

One way to rule out (or in) the rear drive shaft, is to remove it.
Then drive over 10mph using just the front axle.
