The issue happens from a dead stop it pops real loud if i hit the gas hard. Also if i pull up somewhere and stop and put it in reverse to back up it will pop when i start to move under throttle. It will pop sometimes when turning also.. Im lost at where to even begin now ive tried setting the pinion and even welded the cradles to the axle tubes to lock the angle in.

 

Pull your driveshaft back out and slam some grease in the splines that enter the transmission.

If all the grease if gone it will pop/clunk when you take off from a stop. It's the basically free thing to try.

 

Ok cool man i thought about doing that too but this is more of a pop than a clunk. Ill try that tho and see

 

Is it a 2 piece drive shaft or a 1 piece driveshaft? If it's the 2 piece drive shaft check the center Bering make sure it's tight and did you put a shim kit on the center bearing?

Its a 1 piece driveshaft

 

when you flipped the axle, did you push the axle back a little? the centering pin shouldn't be in the center anymore.

 

Yea the plate is put in forward like the instructions said

 

it sounds like you can make it pop on command. why not have someone crawl under there and see where it's coming from?
