Now that concerns me. My adjustable sleeves are so rusted I cannot imagine how they would ever rotate. How you managed to detect the movement AND execute your fix is impressive.

I heard the "shops" don't like adjustables, which is why I've asked here.

Hendersons is emphatic that if the adjustable bushings are installed and torqued properly, they won't come loose in RV service.

Remembered one OP who'd had a problem with them, and pauldub is apparently that OP.

Do you happen to remember what your Settings were on the Bushings, and what Caster/Camber they produced? As I mentioned before, the 4* range interests me because I don't have a way of knowing where the angles will be when I get the springs installed. I don't want to need 3* and only have 2* bushings!

What I'm wondering is if the 4* is more likely to slip like that than the 2*...?

Or just the Luck of the Draw?

The same bushings fit many Fords, maybe even some Dodges. That said, some of the manufacturers don't recommend them for "commercial, RV, box truck, dual wheels, etc. Others specifically say "E450" and there are no E450's with single rear wheels, so that tells me those manufacturers aren't concerned with loosening.

The bushing that moved on me was set at the max angle. I did install a new pinch bolt and re-torqued it but it moved again so that's when I decided to pin it in place. Not much rust here in the west to help it not move.

So you set it for Max Caster (was that 4*?) and Zero Camber?

How'd it drive that way?

Did the Inner slip within the Outer? What did you do when you pinned it? I can picture drilling and tapping for a 1/4" screw and then grinding the protruding pieces off...

I set the bushing for max correction on the passenger side and then gave up a little caster to get the needed camber. I didn't need as much correction on the driver side and that side didn't rotate on me. I don't recall if the inner moved relative to the outer or if the whole thing moved. To pin it, I drilled through the two bushings in situ. I pounded in a pin that was a slight interference fit. The pin is in the pinch slot so the difference in the diameter of the pin versus the width of the slot is all that it can now move.
