I have a 1988 GMC Fullsize Jimmy 4x4. It has a 6-inch lift with 36" Parnelli Jones tires. My problem is that I keep breaking the steering arm studs that hold the steering arm to the top of the knuckle. There are three studs and it's the front two that seem to break and the back one is fine.I've had to replace them twice know and have just snapped them again. The truck has a drop arm to restore correct arm angle but still breaks the studs. Front end has stock 3.73 gears and No locker. Anyone got any ideas whats causing this and a fix for it?
