I have a 1997 Xplorer. Chain-driven four-wheel drive utility quad. Most times when the 4wd is activated the front wheels will pull to the right. I cannot move it. I have to turn off 4wd and run it in Rev for 30-40 feet. Then I can go Forward in 2wd.  What is the problem here?
Some kind of bearing / bushing going bad (running dry)?
Let me know if you've heard of a remedy, fix or campaign.
Thanks
