2001 Chevy S-10 Hit a bump fast=Loss of Steering and Brakin

Jay I think yor prblem is going to be a loose wheel bearing or a bad wheel speed sensor. This is not uncommon. What happens is when slowing down or hitting rough surfaces a wheel speed sensor signal gets lost and drops to 0 mph while the other ones are still reading mph and the abs computer sees this as a skid and applies antilock brakes which will feel like brake pedal is going to the floor and the abs motor sounds as if its coming through the steering column. I would suggest taking it to another repair shop for another opinion because it seems as if the current one is not familiar with this. Gm actually recalled most of these and removed wheel speed sensors and cleaned mounting surfaces and reinstalled to try to relieve this problem

It shuold be easy to diagnose for the shop which wheel is it by driving truck with a scan tool attached and watching the wheel speeds. You should expect to pay 1.5 hours labor and 175 dollars for the hub and bearing assembly. The hub comes with the speed sensor in it and this is usually the fix
