Sounds like hog wash to me. It needs a new isolator for starters, then the castor set correctly. With 4" of lift you have pushed the limits of alignment for stock control arms etc. Hopefully that kit had a drop or extended control arms with it?Thanks for the information.
I took it to a shop and they tried to reseat the coil. When they put the coil back under tension it just popped out again. Is it possible that the spring is bad? The shop said that the coil has “memory”and I need to replace it.
It's possible the kit re-used the old isolators but re-indexed them, which means the installer needed to drill a new hole and rotate the isolators into new positions. That's how my BDS kit worked. Get the instructions for the kit. Compare what they say with what you see. Make sure the end of the coil is lined up with the right spot on the isolator.
The spring perches on these trucks tilt forward naturally. Bowed springs are not uncommon. A springs off its upper seat is not normal, though.Finally got back to looking at this. The canter is set different on both sides. The passenger side is set at 11 and the spring sits correctly. On the driver side it’s set at 5 and the spring sits off the isolator.
How to I set the canter so it’s correct?
