Detroit, Michigan – General Motors is recalling 26,751 full- and midsize pickup trucks in the U.S., expanding a recall to replace a rear axle cross pin that could fracture.

The original recall of 1,262 vehicles announced in December 2010 is now expanding to include 26,751 Cadillac Escalade, Escalade ESV and EXT models; Chevrolet Avalanche, Colorado, Silverado, Suburban and Tahoe models; and GMC Canyon, Sierra, Yukon and Yukon XL models. Owners are being contacted and urged not to drive the trucks until the axle pin is replaced.

On certain trucks, the rear axle cross pin may have been improperly heat-treated and could fracture, causing the axle to lock while driving. If the pin fractures and becomes displaced within the rear axle, the driver may hear a banging noise coming from the axle. If the pin shifts out of position, it could create an interference and cause the rear axle to lock. In this situation, the driver may not be able to maintain directional control of the vehicle.

GM said it knows of one incident in which a driver experienced loss of power to the axle, but there was no crash, and the company is unaware of any crashes or injuries related to the condition.
