Why would the truck grab (and make grinding noise) when hits a bump or in reverse?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Michelle, It would "grind" in a manual or "stick shift" if the synchronizers in the transmission were not aligned properly when shifted. The shocks may be faulty when you hit a bump the tire may hit the underside of the fender well. Hope this helps. AJ Pierce

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Michelle, I would need more information on when this is happening. Are you shifting when this happens, or braking, or just driving along with no gear changing or anything? Grinding when shifting could be an issue with the transmission. The grabbing over bumps when you're braking can be normal in a truck because of the lightness of the empty truck bed. When is bounces in the air, it feels like it's grabbing because one of the tires is not connecting with the road surface. Hope this helps. Lori Johnson www.ladiesstartyourengines.net
