The 2006 Silverado has chronic problems with its front wheel hub bearings and assemblies. Owners report grinding noise, abnormal steering feel, and ABS warning lights appearing well before wheel failure, but some failures happen without warning whatsoever. One owner's tire detached at 40 mph and caused a crash; another had braking system failure tied to hub bearing breakup. Wheel hubs fail repeatedly on the same truck — one owner replaced the left hub four times and the right hub twice.
The hub assemblies are sealed cartridges that cannot be regreased; any bearing failure means replacing the entire assembly for $300–$750 in labor plus parts. Owners report this happens at mileages as low as 19,000 to 45,000 miles on highway-driven trucks. Multiple mechanics told owners this is a known design problem and that bearings "just go bad immediately without warning," making early failure a foregone conclusion.
A separate issue affects the spare tire secondary release mechanism, which jams and cannot be operated even by professional mechanics. One owner was stranded in the Colorado backcountry for six hours unable to access the spare. Owners also reported tire defects unrelated to the hub issue.
Failure modes owners describe
Wheel hub assembly detachment
The wheel hub assembly separates from the vehicle, causing the tire to detach from the vehicle during operation. This failure occurs without prior warning or obvious symptoms in some cases.
When: Low mileage reported; one failure at unknown mileage, one at 35,000 miles with both hubs failing within weeks of each other
Symptoms owners cite: Abnormal thud-like noise before failure; No audible warning in some cases; Loud scraping, crunching, popping noise from affected wheel
Repairs/costs cited: Wheel hub assembly replacement; owners reported mechanic shops kept old parts and noted this is not an uncommon incident
Recalls/TSBs owners mention: NHTSA Campaign Number 07E106000 (Wheels) cited by one owner; manufacturer informed but vehicle not repaired in that case
Front wheel hub bearing failure
Sealed wheel hub bearings fail prematurely, causing grinding noise and potential loss of braking function. The hub assembly design does not allow for field lubrication. Owners report multiple failures on the same vehicle.
When: Failures reported between 19,000 and 104,649 miles; some vehicles experienced two failures within weeks
Symptoms owners cite: Loud grinding or whirling noise from wheel area; Unusual bump sensation followed by stiff steering; ABS warning light illumination; Wheel turning inward abnormally; Braking system compromise; Wheel wobbling on lift; Unexplainable tire tread wear; Vehicle pulling
Codes mentioned: ABS warning light
Repairs/costs cited: Both front wheel bearings replaced; typical repair cost cited as $750 plus brakes and rotors replacement; one repair cost $377; sealed design prevents field relubrication and necessitates full hub assembly replacement
Recalls/TSBs owners mention: One dealer blamed condensation as cause; another dealer advised extended warranty purchase and refused warranty repair; one VIN confirmed not included in NHTSA Campaign 07E106000
Spare tire secondary release mechanism failure
The spare tire secondary release mechanism jams and cannot be operated, leaving owners stranded with no way to access the spare tire.
When: Occurrence timing not specified; owner reported spending 6 hours attempting to release
Symptoms owners cite: Spare tire secondary release will not operate despite repeated attempts; No visible way to release the tire
Repairs/costs cited: Spare tire remained stuck even after local garage attempted repair; owner described as common problem on Chevy trucks
Tire tread and belt separation
Federal Couragia MT tires experience tread and belt separation, creating bubbles or bubbling on the sidewalls after moderate mileage.
When: After approximately 16,000 miles on 2012 Federal Couragia MT 33/12.50/20 tires
Symptoms owners cite: Tread and belt separation; Bubbles or bubbling on tires
Repairs/costs cited: Tires rotated regularly and pressure maintained correctly
