Front Suspension Lower Ball Joint Problems of GMC Sierra 1500

The contact owns a 2019 GMC Sierra 1500. The contact stated while driving 65 mph, the front driver’s side tire detached from the vehicle. The contact stated there was no warning light illuminated. The contact was able to park on the side of the road and noticed that the ball joint had separated from the a-arm. The vehicle was not drivable. The contact towed the vehicle to the local dealer, where it was diagnosed with needing the front driver’s side tire, ball joint, and the upper a-arm to be replaced. The vehicle was not repaired but was pending repairs. The manufacturer had not been informed of the failure. The failure mileage was approximately 43,000.

Took 2008 GMC Sierra 1500 4x4 to tire store to rotate tires. They indicated that the lower front ball joints were loose. This truck has 77,000 miles so I was skeptical. Took truck to GMC dealer for service & requested that they check the lower front ball joints. They indicated that the ball joints had one quarter of an inch of vertical play and were indeed loose & needed replacement. I have earlier GMC trucks with over 200,000 miles and have not had worn lower ball joints. I believe that the looseness is due to the ball joint pulling apart. The wear was not side to side as would be expected. I want to repair this defect so as to avoid a catastrophic failure of the front suspension. I want to use oem parts but I am concerned that these ball joints are defective. The GMC dealer advises that even though the truck has a 100,000 mile power train warrantee, the ball joints are not covered.
