Ex850R

Anyone used the IPD HD drop links/swaybar links and had a failure?
Mine were on my S70 T5 for only 20K kl/m maximum then put on the V70T for less than 10K kl/m and the LHS started to clunk and got very bad when i went on a trip in heavy rain as the car pulled itself into standing water , very scary with the family on-board.....
I need to trace when i bought them from a local re-seller but it was a few years ago when i had the 850R manual wagon and they were not put on that car.
It seems like premature failure , so much for HD, thicker bar maybe but inferior ball joints.....
So now i have one HD and one STD Volvo on the left....
