when the car is at 65-70 mph, the front passenger seat vibrates

I just had the wheels re-balanced and tires rotated and it still does this

could the seat be loose?

was the vibration present before you got the tires balanced and rotated, or it just started doing it after that? how many miles on those tires, and how old are they? does the vibration occur at higher speeds than 65-70mph, or only at that speed?

the vibration was present before and after- there are only 7000 miles on the tires and i have replaced just about every bushing there is as well as shocks

That sounds like further evidence that your passenger seat is loose. I know there are bolts that enable you to tighten it, but I'm sorry to say I don't know which ones or where they are.

what about the speed, only at that speed or at higher speed also? i might be misunderstanding what you mean by vibration, just the front passenger seat vibrates, or the whole car. can you feel the vibration when you're driving?

just the seat- that is what was making me nuts- you can see the seat shaking, but the car is not shuddering or vibrating, and it is only between 65-70 mph

Thanks

Heres what I would do. Find yourself a pretty young lady about 115 lbs. Make her ride in the passenger seat "topless" whenever you drive. That should stop the seat from vibrating.................:D Cant guarantee that something else wont start to vibrate though!

Actually have you replaced your tie rod ends, inner and outer, and checked the lower ball joints? My car did pretty much the same thing but once I replaced these items and had the dealership align all 4 wheels it was much better.

I installed new tires yesterday. Got Bridgestone G019 all season radials, 215/55/16's. Look really good with an aggressive tread design. Car also rides much tighter too.
