I swapped a 2000 beta 1 motor and a 2001 tiburon transmission into my 96 elantra and Im getting a knocking noise when I accelerate, decelarate and hit bumps. I think its from the axles which are the original 96 units in the differtial. Does the 2001 tiburon use a different size axle than the earlier tibs and elantras. The knocking might also be my steering racks inner tie rod. I want to fix this befor I end up on the side of the road or worst. Help?
