around 90MPH my car starts to shake kind of like a vibrator what parts start to get worn after a while my car has 120k miles what should i start replacing i already got shocks

 

maybe you need an alignment?

 

i got new tires from les schwab i think they did one. i will take pics of my bushings and stuff an post them sometime

 

I have the same problem at 60MPH.

I think it would either be the driveshaft is unbalanced or I need an alignment :O

 

with every car ive ever driven, new struts, reblancing of the tires, and an alignment have cured all *MPH vibration.

 

Its obvioiusly not 1sxy's problem, but shaking can also be caused by bad tires. When I bought my car it had a constant bad vibration above 60 or so. The previous owner had been told it was a worn shock, but it turned out that the cheap-*** used tires he had on the front were actually starting to seperate. Just another thing to check before you start throwing money at stuff.

 

I have the same problem from about 65 up. The only difference is that mine vibrates pretty bad sometimes, but it'll vibrate hard, smooth out for a second, vibrate, smooth, vibrate smooth, and such.

 

yeah i HAD the same problem ... bought two new tires, and had the others rotated to the back ..


fixed it

alignment, and rotating tires seems to be fix

 

i got all new tires and shocks, i think it might be worn ball joints or somthing

 

New ball joints fixed my 90+ shaking...

 

im getting some vibration starting around 140, what would cause this? same things?

 

mine gets really bad at 120 its like im in a giant vibrating *****

 

If all that other stuff checks out, take a peek at your transmission mounts and engine mounts. Mine (trans) where shot and the car vibrated at various speeds, It had more to do with RPm that speed though... Just something to check.

BTW it is in the FSM and haynes manual, and if you need parts try mazdatrix...

 

mine vibrates around 65 and up. and the shift nobe vibrates up and down avobe 70 MPH. It all started when I hit a curb onece goin sideways, I replaced one of the linkes that was bent.

interesting thread.

 

...

 

check you wheel bearings aswell

mine does the same thing - and i have no idea where to start

had the alignment done - that didnt work - all the wheels balanced - and it still didnt work

the only thing different - is that mine pulls to one side aswell

damn these cars are quirky
