Qualis automotive is recalling certain aftermarket ball joints sold for use on certain passenger vehicles. The socket may have been excessively hardened which could cause it to crack near the retaining ring groove allowing the ball stud to separate under impact load. The subject ball joints were sold as four part numbers, D10945, D10946, G10945, and G10946. The affected control arms, D10945 and D10946, are stamped with the following dates on the ball joints: 134308, 135708, 100109, 102709, 104109, 105509, 107609, 108909, 110309, 113209, and 116609. The G10945 and G10946 are the same part as the D10945 and D10946 respectively. They are labeled differently depending on the aftermarket customer.
