Car is a Weurth, guessing weight is around 2200lbs, not a very heavy car. Ive only had it for 2 years so don't know previous driving style or conditions. I do sand only with a family and kids in the back. No jumping or pounding woops. It broke right outside of camp shifting from 2nd to 3rd gear. Was just a matter of time I guess and that's when it let go. Glad it let go when and where it happened. 3 wheeled back to camp and took to Joe fab and he welded a new king kong on the spindle and after the trip tore it down and sent to Alper for 2" upgrade. Much better piece of mind now.
