tranny ? again

Yeah, Brad called me after he talked to you and we agreed that'd be a good start.

The big question I have is-- did this vibration start when you swapped in the new axle? If so then that narrows it down quite a bit. Couple other ideas if the u-joints don't pan out: is the pinion nut tight? Is there play in the pinion? (might need a new bearing or bushing). I also replaced a brass bushing that was in the tail housing of my transfer case (you probably have one in the tail housing on your tranny) when I was hunting down a vibration-- that could also cause a vibration like you're saying.

I don't think the flexplate is your issue because my understanding is that this is only happening at higher speeds. Everything forward of the transmission is completely speed-independent. The only things that spin at different rates with different speeds are from the trans-->back.

Start with the u-joints and report back.

yeah im gonna do that tomorrow afternoon.

and no the vibration didnt start when i swapped rear ends. its only been going on for bout 2 1/2 weeks maybe 3 weeks. and ive had that rear in my truck for bout 4 1/2 months.

GAWD DAMMIT!!!!!!!!!!!!!!!!!! THAT MOTHER****ING VIBRATION IS STILL THERE!!!!!!!



ugh im so freaking pissed.

remember when ya rev'd the motor with it in park? ya said the vib was still there just not as bad? that means it isnt in the driveline. it's from the torque converter to the fan belt.

no. especially not after lining up the u-joints the vibration went away.
