TRX 300 FW Front Wheel Locked Up???

I was riding our 1995 TRX 300 FW 4×4 and heard a noise in the front left wheel area and a few minutes later the front left wheel locked up and dragged for about 10 feet. I stopped and got off and didn’t see anything unusual. I did just replace the knuckle bushing on that corner so it was all torn down recently. It rides fine otherwise. It does have a Warn 424 unit and it was in 2wd when it happened. The 424 seems to work properly after this occurred. Any ideas why that front wheel locked up??

TIA
