Suspension on my '03 21Rb Bigfoot
has been getting very noisy so I took it apart. Looks like the inside of the shackles are rubbing on the leaf spring eye. Some metal has even been gouged out.
Just starting to research what the best approach to rebuild it so it is quieter. Maybe wet bolt kit? However, even with the wet bolts it seems there is going to be metal on metal contact between the leaf spring eye and shackle. Should there be some sort of nylon washer between? Or would it just get chewed up in a short time?
Would something like this Dexter Heavy-Duty Suspension Kit https://www.etrailer.com/Trailer-Lea...71-449-00.html
be worth it? This particular one wouldn't work because the axle
spacing is for 35" and mine is 31". Also, the equalizer is only 2 7/8" tall which would make the suspension lower. I'd like a couple of inches of lift. I've thought about an axle
swap but that would be over 4" (according to my calcs), a little more than I want. Do people ever lift trailers by installing higher equalizers? i.e. my equalizer is about 3 3/4" high now. If it was 5 3/4" wouldn't that give me about 2" of lift?
I'm not totally sold
on the need for the wet bolts. I've never had wet bolts on any of the leaf springs on pick-up trucks and they last for >100k miles.
Thanks for any insight.
PS: I guess they installed the suspension before they put the tanks in. The left rear leaf spring bolt is right up against the tank. That bolt will be remaining as-is because I ain't taking the tanks out to put a wet bolt in
