new tires
MY DREAM said:So I tried it at all different speeds that the vibe occures at, and every time I pushed in the clutch it went away. That right thier would tell me that from the drive shaft back to the rear wheels everything is good cause with the clutch pushed in, from the drive shaft back everything is still turning the same speed as before. Now when you do this the clutch will slow down and the engine RPM will also slow down. Does anyone think that this could be a clutch prob?

racebronco2 said:a ford powertrain tech told me that the problem occurs because of the pinion angle is in-correct ..... in first and second they is sufficient torque to compress the bushings in the irs dif ... but once you shift into 3,4,5,6, the vibration starts ... you what is needed is to add shims,washers etc between the irs and the irs brace/ remove, trim the bushing between the irs dif and the cage .... the front of the dif needs to be raised to correct the problem
once you put the car in nuetral and the vibration stops then the problem is your clutch or tranny

However the vibe going away with the clutch down does not mean there is nothing wrong in the driveshaft, diff etc. No-load vibration (or lack of it) is not the same as load vibration as any worn bushings or u-joints under load can cause a vibe.
A better test is to roll along a flat road in calm conditions, accelerate lightly to the 'vibe speed', then let off the gas pedal to see if the vibe goes away. Even then, if the vibe lessens, it could still be any worn or out of balance part in the driveline.
My drag racing friend tells me the symptoms on my car point to worn u-joints. I'll check with the dealer to make sure they were replaced last time they tried to fix the vibe. They are trying again soon.
I have a new Fidanza wheel and CF DF going in soon so I'll let you know if that makes any difference to the vibe.
The only real way to find the cause is to put the EARS on the car and methodically find the vibe source then replace/fix parts to eliminate it. That can be a time consuming process so dealers may be reluctant to do that if Ford won't pay them the shop time (even it it leaves you an unhappy customer).
