The car shakes when I drive. I've especially noticed at highway speeds around 70 it'll like stop for a second and then shake bad and then stop and then shake, etc. like every second. Usually it has a small shake all the time though and the steering wheel shakes in my hands. I have a basically whole new front end....center link, idler arm, struts, inner and outer tie rods....rear shocks and stabalizers also brand new. Front has been aligned and wheels balanced twice. I know my trans mount is bad and Im replacing it tommorow, don't think it would cause this though.....any ideas? Hard to have a pimpn' ride when it shakes you all around lol.

 

You might have a broken transmission mount.

I have a van that I chased a highway-speed shaking problem for 6 years. I won't even list all the things I replaced. Turned out to be tires - including two new sets that were as bad as the ones they replaced. 16 tires had been on the thing before I had 4 that didn't shake. Repeated balancing didn't change anything - they weren't round at highway speed.

 

Almost sounds too bad to be a driveshaft out of balance.

 

I know you said you had your front end balanced..

But you can also get your car speed balanced.

A normal balancing doesn't mean it will keep your car from shaking at higher speeds.

Call and check around to see who speed balances.

 

My bet is on the tires. I had a set of tires that the steel belts had seperated from the tires and had a bad vibration.

 

I agree, that was my problem after the car sat for a long time waiting for me to replace the motor. The tires flatspotted and caused vibration.

 

might wanna check your driveshaft (as said above)

aluminum ds will stop alot of the wobbling.

 

Thanks a lot for all the tips. By the way two things, I DO have a broken tranny mount which Im replacing tommorow, hoping maybe it clears up some of it. Also, its not JUST at highway speed that it does this, it shakes all the time at all speeds. Its just that at highway speeds of say 65+ it acts more odd. It has the one second ok next second it shakes thing going on. Hoping to get a grip on what the heck is going on down there tommorow when I change trans mount. It's not a horrible undriveable thing yet...just more of a constant annoyance.

 

couple more things...Ive noticed the shake is coming from the rear. It only started after the shop redid all my brake pads and shoes...car also pulls to the right slightly and steering wheen stays slightly off center toward the right....any more ideas?
