1991 mustang vibration problem
I have a 1991 mustang with a vibration problem. I replaced everything except I do have a sticky brake caliper on the passenger side an it evens vibrates when im accelerating could that be my problem?

Not likely, but explain your vibration in a little more detail. At what speed?, is it in the steering wheel or do you feel it in the seat ?, mostly on acceleration, braking, or no load cruising speed?
Be as discriptive as possible , so we can narrow it down for you.

A sticking brake caliper (depending on how it's stuck) would just be providing constant pressure. The only way I can think of this creating a vibration is if this pressure overheated the brakes, causing the rotor to warp.

could be a number of things, driveshaft bolts loose, worn out u-joint in driveshaft, wheel balancing weights could have fallen off, front wheel bearings could be worn, rear axle bearings could also be worn, axles could be bent, I would rule out brakes since it does it while accelerating.

I have new tires an theve been balanced twice. New motor mounts, shocks, struts, rotors and front wheel bearing an a new rack and pinion but, I do know the passenger side tie rod end has been patched up an I also had the dealer check the drive shaft an they said it was fine. But yes I feel it during acceleration an breaking by how the brake pedal feels. It does it off an on at times very strange.

II don't know what a tie rod thats been " patched up " looks like, but I'd like to lol.
Seriously though, anything that rotates can cause a vibration, Most of the parts you threw at it would not cause a vibration . An intermittent vibration is going to be very hard to chase down with the discription your giving. I'd start with u-joints first, based off what your saying.
The pulsing brake pedal is a warped rotor.

I wouldn't................................I can't believe all of the previous posts have discounted a dragging brake caliper as "not a possible cause".......................I can't tell you how many cars have come into my shop with a dragging caliper on one or both sides and the complaint from the customer is car has mild and or bad vibration...........due to the caliper dragging and thus having overheated/warped the rotor..........OP, FIX the caliper first and verify no calipers are dragging to eliminate that as a cause...........and YES A CALIPER DRAGGING/STICKIN WILL CAUSE A MILD/BAD VIBRATION WHILE ACCELERATION AND OR DRIVING DOWN THE ROAD AT SPEED. You have to eliminate this as an issue before going any further with diagnosis.
