Earl -
I never had any issues with the suspension on my 2008 5th wheel but someone advised me to check the various parts - shackles, bolts, bushings, shackle hangers, etc. When I did inspect them (in 2010) after 2 years of wear, I was both surprised and shocked to find the thin, nylon bushings were almost worn through and the "round" holes in the shackle links were no longer round but oval shaped from wear.

I looked at the suspension on all four wheels and the wear on them was the same - badly worn nylon bushings and oval-shaped holes on every link.

I took the parts down to a local shop that specializes in alignment and suspension and they showed me what they should look like as well as the same parts from a wet-bolt kit.
The links were almost twice as thick and the bushing was bronze I believe rather than nylon. The service manager told me that these original parts are cheaply made of the thinnest metal possible and he has seen and replaced dozens and dozens of these things with better quality parts.

If you have never had them inspected, it might be worthwhile doing so before you do have a problem. I don't believe its "a solution looking for a problem" but instead replacing something of poor, cheap quality with something more substantial and longer-lasting. I guess it's similar to replacing China bombs with a better quality tire.
