drive shaft may be binding up.

drive shaft may be binding up.

This. Can't think of anything else... check your drive shaft angles.

I live not to far away in Norwich, work right down 95 in old saybrook

[grundlepunch]

yeah, throw your t-can in neutral and go underneath your rig and peep whats going on under there

oddly enough i put a transfer case drop and everything stopped clunking. im guessing my pinion angles were off just enough to make it act up. pretty pumped. took it down to town fair tire and got an alignment after i cut some stuff out so my wheels wouldnt rub at steering wheel lock.

What was probably happening was that the driveshaft angles were changing due to torque while on the gas, causing binding. I have a little bit of this happening at the moment. Everything looks good when you hop under the rig, even though they aren't. Glad to hear it's fixed tho.

i would still do a sye though totally worth it dude.
