I bought this car about 1 month ago. It's a 03 2dr v6 6 Speed. 65K miles. I'm having problems with the car since then.

I fixed all of them(Brake Rotors, pads, Drive belt, wipers, tires, something else too - can't recall it now)
but 2 problems remain.

1st - the biggest and most annoying is vibration from about 50mph till about 75. Sometimes it's not there at all, sometimes it's impossible to drive it, but most times it's mediocre. It happens only when accelerating( hard and not hard) from ~50mph in ANY gear. It's fine when cruising.

I've checked:
suspension - fine
motor mounts - fine
hubs - fine
Tires balanced(I changed fronts) - the vibration was before changing tires and still there, I even put rears to the front to rule out bent rim. Still there.

My mechanic says it might be drive axles.
I'm starting to think about clutch. at 65K - wierd. It doesn't slip or anything. it doesn't vibrate when I'm trying to ride it. pedal seems fine to me.


2nd - driver power seat. When I drive I like to seat back to be up, but last week I gave the car to my friend to go to the store and he put it down and now I can't lift it up. It lifts a little and then it makes "grrrrrrrrrrrr" sound and doesn't move. I tried to move the back manually( there is a lever there to get in and out) After that it moved up a little but still not there as I'd want it to be.

Can anyone suggest me something?
may be someone had similar problem(s)?

Thanks

 

well... i can tell you that your seat issue is most likly the motor.
as for your vibration.. the only thing i think u didnt mention is tie rod ends, but i doubt they will give you that much of a vibration.

especially since your problem is vehicle speed related. id say re-check your wheel bearings, and make sure the axle nuts are torqued to spec.

 

lower ball joint could cause vibration..... but it could be an axle that lost it's balance.....

 

The motor works in the seat

then id say that theres a mechanical resistance in the seat. somethings binding.
