This monday I swapped a 10 bolt out of my 99 Camaro for another 10 bolt and also replaced my dented driveshaft with a used good condition one, along with a new UMI adjustable torque arm. So I got everything back together, adjusted the new torque arm with my brother in the car to represent my weight, then took it for a test drive. The whole ride felt good, except my driveshaft making this thunking sound on every bump or when I decelerate. The pinion angle is set at -1.4 degrees if that would cause anything
Please help

Did you check the u-joints on BOTH ends of the used driveshaft (and/or grease them if they have zerk fittings)??
