I have a 2000 K2500 crew cab 4X4. When I engage my 4 wheel drive and turn right or left my front wheels bind up and sometimes lock up on me. It only does it in 4 wheel drive and if I am turning left or right it does not do it if I am going straight in 4 wheel drive or if I have it in 2 wheel drive. I have had a diagnotic done on it and it didn't give me a lot of info excetp that my speed sensors where reading 3 m.P.H. When I was not moving even in park. I would appreciate any info you can give me. Thanks

This may sound crazy, but the most common cause of this problem is different size tires or more worn tires on the front or rear. The next is the spider gears in the front differential are not compensating for the outside wheel turning faster than the inside wheel in a sharp turn to left or right which binds up the transfer case. Lastly, the clutch in the transfer case should compensate for differences between front and rear output shaft speeds. If the truck has seen a lot of "4 wheeling" this clutch may not be compensating like it should. Hope this helps and thank you for your donation.

Thanks for your quick response. One more thing if it helps. I started having problems last year, but it was very intermittent I went ahead and took it to a repair shop and he thought that the abs sensors were bad and causing the brakes to be applied when I was turning the wheel because of one wheel turning faster that the other enough to cause the abs sensor to trigger. Just so happens on my truck I was told the sensor is in the hub and the whole hub assembly has to be replaced because of the sensor. If this makes since and is possible please let me know. Thank You.

The ABS system will only come into play only if one wheel stops while you are moving. To test his theory, you can pull the fuse on the ABS system, which will disable it, and take it for a test run turning left and right corners. Let me know what happens.
