Alignment.

[Rbroadwater1]

I just had to replace the tires on my 2009 Designer. The tires wore on the sides like it was out of alignment. After inspection it was discovered that a nut was missing on a spring shackle and the other was almost off.
They will need to be replaced and the axles realigned . Has anybody else had that problem?

Not bolts missing. There should be a local frame alignment shop in your area. Ask around at some rv shops or truck stops for a reference.

It should not be a expensive fix.
