Rear differential mount was not installed.
Conclusion: Subject vehicle was picked up by owner after 6 months in an insurance shop. Owner brought the vehicle in for post repair inspection due to suspension problems. Vehicle was inspected and the following was found: Used rear suspension was installed incorrectly and was damaged. Rear cradle was damaged and not replaced. Rear differential mount was not installed. Upon further inspection it was determined the rear fender was not fitting properly due to a poor repair. Removing the fender section revealed it had been amateurly welded back together instead of replaced. Furthermore these welds were not properly sealed and will eventually corrode leading to bubbles in the paint and possibly failure of the part.
