Upper control arm ball joint out of grease?I finally decided to take the entire front suspension apart and found the problem. It was the upper control arm. The part that holds the knuckle was completely drain of all the fluid. It left to the joint free to move around and clunking as the suspension went up and down. Instead of getting it replace with the same old Telsa defective part, I opted to go with the MPP FUCA. Now the car is riding perfect with no noise and a better handling responsiveness.
