so i have an 88 t2 all stock (wheels are torqued lol) so when im crusing on the highway at 60, the whole chassis shakes, but its like a pulsing shake it, it will start to build- peak- then die off and do it again. i thought it might be like an engine mount or something but usually if its that bad it shakes all the time. my buddy said its my wheel bearings!?, what do you guys think it might be?

 

Try getting your wheels balanced.

 

Have you checked the wheel bearings?

 

I forgot to mention I did do that

 

There is a little bit of play, and I noticed a faint growling noise

 

I had a bad shake about 50.it was a ball joint.

 

Me too. Check your balljoints.

 

Have you checked the u-joints in the drive shaft. When mine went it was making the car shake like a son of a bitch, had to drive back from central tn, to charlotte, nc like that >.<

 

ill check them and let you guys know

 

If you say you're hearing growling noises, then most likely it is your bearings. They could be shot due to lack of service, replacement, or a number of other things. Mazdatrix has relpacement bearings available, as well as the seals. It could be expensive, but well worth it if that is the problem.

 

Check the drive shaft to see if it threw a balance weight or picked up some debris that is sticking to it.
