In December 2020, Fox Factory received its first reports that certain GM vehicles fitted with Tuscany lift kits could experienced partial or complete wheel separation while in operation. Fox began reviewing field data and started a safety investigation to assess the failure mode, the failure rate and potential causes of the problem. By September 2021 Fox identified 28 warranty claims and field or service reports potentially relating to this issue and decided to initiate a voluntary safety recall.
According to the defect report, “Accelerated wear on the vehicle OEM installed ball joint in the front upper control arm can result in premature ball joint failure and a front wheel separation while the vehicle is in motion .”
Failure of a ball joint in a front upper control arm may be preceded by noise and / or a feeling of clicking in the steering, abnormal front tire wear and abnormal steering.
|The Vehicles Affected Include:|
|2019-2021 Chevrolet Silverado 1500|
|2019-2021 GMC Sierra 1500|
New Tuscany front upper control arms will be installed in place of the GM front upper control arms. The fix will include upgraded front upper control arms with stronger and less corrosion sceptible ball joints. NHTSA Campaign Number: 21V718.
