[RICK LAKE]

DaleB Dale need to break down when this problem happens. With 300 miles, I am guess all new parts. This doesn't mean the there is not a problem with back lash in the rearend or trans problem. When does the noise happen? Hot,Cold,Speed, Accel, Coast down to stop, Brakes applied, car just sitting.
It is possible to get a clunk noise if the driveshaft is too long and the pinion angle goes from neg to pos. The drive shaft could bind when the angle reaches "0". Any thing is fixable. i will look at the ad when get a change. Find out what posi carrier is in the rearend. Rick.
