My 03 with 101K miles has developed a "seat of the pants" vibration under full throttle. I feel it the most in second gear but cant swear that it is as smooth as it used to be in the other gears.

It does not seem to be related to left or right turns.

Could it be motor or transmission mounts or is it most likely the half shafts?

Any thoughts, comment or suggestion are appreciated.

 

Sounds like motor mounts. Can you feel it in the shift knob?

 

I feel it more in the whole car. Like I say, seat of the pants

 

i have the same problem myself. i think its its my axles. im at 82k miles though.

 

CV buckets?

 

same probelm and at 65k 2002

i posted this problem a while back and everyone said its probley motor mounts
but idk, its a start to try and fix it right?

and does your shifter vibrate?
mine goes crazy stopped at a light on a hot day

 

No shifter vibration. I am leaning toward the axles. I have been in touch with my shop and are discussing possibilities.

 

There have been endless threads on this.

Pitted axle buckets, 100%. Record low miles for this so far is 29k.

 

I agree I guess I did well at 100K

 

I had this issue Capt'n and John @LHT hooked me up with some Gator axles. Smooth now.
