Hi i'm Tim west heres some

Hi i'm Tim west heres some pointers on the 4wd system. Things to look out for and some test that you can perform: Check the transfer case fuse. Need to validate tire rolling circumference when diagnosing driveline bind and/or transfer case clutch failure for the New Venture Gear (NVG) 126, 136, 236, and 246 transfer cases. 1. Visually inspect tires and determine that they are a matched set. 2. Check air pressure in each tire and adjust as needed. 3. Mark all 4 tires at the 6 o'clock position with a chalk mark. 4. Drive straight ahead ten revolutions and stop with one wheel mark at 6 o'clock. 5. Verify that all 4 tires are within 1" of the 6 o'clock mark. Check for codes with another brand of scan tool. Check the transfer case shift motor and encoder switch wiring. Check the transfer case shift motor wiring through connector 131 a black 7 pin connector near the booster
