thanks mike, luckily I was in the far right lane, anywhere else and there would have been an accident with as many cars as were on the road....it went with no warning at all and immediately steered me hard to the shoulder. Actually I thought I had a flat tire at first. There was a guard rail so I couldnt pull off but after a few seconds it straightened out for the most part and I was able to safely get off the interstate to check it out. Fried the inner spindle lock nut, disc and bearings. I had to take it off in one big chunk from the spindle out. luckily i have alot of spares.
