Product Details

The ATP Parts Front Axle Disconnect 111001 is a driveline and axle component that controls engagement at the front axle. In normal operation, it allows the vehicle to disengage from four wheel drive or all wheel drive and return to rear wheel drive. That function is important for maintaining proper driveline operation on vehicles such as the GMC Envoy and Chevrolet Trailblazer, where the disconnect assembly is part of the front axle system.

Fitment includes 2002-2009 GMC Envoy, 2002-2008 Chevrolet Trailblazer, 2003-2008 Isuzu Ascender, 2002-2006 Chevrolet Trailblazer EXT, 2002-2006 GMC Envoy XL, and 2004-2005 GMC Envoy XUV. The ATP Parts 111001 part number is a direct reference point for identifying the correct front axle disconnect assembly for these applications.

What It Helps Fix

• Front axle disconnect failure that prevents proper 4WD or AWD disengagement
• Driveline binding caused by a disconnect assembly that does not release correctly
• Loss of rear-wheel-drive operation when the front axle remains engaged
• Noise or wear related to the intermediate shaft bearing housing disconnect assembly
• Service replacement needs on GMC Envoy and Chevrolet Trailblazer driveline systems

Installation Notes

Verify vehicle year, make, model, and driveline configuration before ordering. This part is also called intermediate shaft bearing housing disconnect assembly, bearing front wheel drive intermediate shaft, splined disconnect, or gear pod, so compare the original unit and OE references during diagnosis. Drain plug is not included, and the 111001 should be matched to the existing front axle disconnect setup before installation.

Quality Assurance

ATP Parts supplies this front axle disconnect as a new assembly rather than a remanufactured unit. The part is supported by OE-style interchange references and application coverage for select GM and Saab SUV driveline systems.
