I have a 99 GMC Yukon, 5.7L that is stuck in 4WD. I took it to a GMC dealership and their service department said it is the ENCODER MOTOR that needs to be replaced. They quoted me just over $900 and I am wondering if this is a reasonable price? Also, how big of a job would this be to tackle on my own?

Thanks-Nate

2. Remove the four bolts that secure the motor/encoder to the transfer case.

Installation Procedure

1. 
   
   <LI type=1>Install the with a motor/encoder. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
   <LI type=1>Install the four bolts securing the motor/encoder to the transfer case. Tighten
   Tighten the motor/encoder bolts to 25 N·m (18 lb ft).
   
   • Remove all gasket material remaining from the motor/encoder.
   • Ensure the motor/encoder aligns properly with the transfer case interior shifting components.
