6. The rear has remained the same double-triangulated four-link that it's been. The QA1 rod ends have seemed to last through the beatings as well. But I did have an issue where the jam nuts became loose, letting the rear axle walk sideways and snapping a coilover shaft. I had to replace this driver side coilover shaft, and add a new coil since the old one had caught and bent in a "U" when the shaft broke. I had the old shock rebuilt and it's bolted to the truck's rollcage as a spare in case somehing happens again.
