When i am driving in 5th or 6th gear i get a grinding type vibration in the accelerator pedal, it kinda worries me. does any one have any ideas on what this might be?
Thanks in advance

 

Wheel bearing?

 

i really dont think its a wheel bearing it doesnt seem to come from there. for some reason i am thinking tranny

 

I just had a wheel bearing replaced the other day. My symptoms were very fine vibrations from about 55-65mph, in 5th and 6th gear. I could feel the vibrations in the pedal and the steering wheel. I would also check your carrier bearing on the driveshaft. You don't seem to have much power mods so I would find it hard to believe you sheared teeth on 5th and 6th unless you are towing excessively heavy and roughly. JMHO
