I just pulled my steps apart from top to bottom. I had 2 bolts shear off at 2 different times. What I found was that the bushings, bolts and brackets were freezing (oxidation etc) up due to the lack of lubrication. The bolts seemed to be breaking due to the torque and the lack of them being able to move freely in the bushings. I bought several new bolts,bushings and nuts from Lippert (by the way it's cheaper buying by the piece than an assembly) and installed them lubricating the bushings inside and out with a small amount of grease. No more squeeks, moves nice and free.
The other thing I did since they are so well painted (not really) from the factory is I took a heat gun and removed the anti slip strips, cleaned the excess glue off with thinner, scraped and knocked off the loose paint, wired brushed them, painted 2 coats of Rust-Oleum Rust Resolver primer, excellent stuff, and then painted 3 coats of Rust-Oleum gloss black. If I had thought earlier I would have used their bed liner product instead of the paint.
The steps used by Forest River are made by a division of Lippert Industries which is a giant holding company that makes many products for many RV manufacturers.
For those of you who put your steps (RV) away for the winter I would pull (1/2" wrench and socket) each bolt out and stick a little grease on the shoulder of the stair bolts and inside the bushing. For those of you who don't to take the time to do this I suggest spraying area where the bushings are with WD40 or equal liberaly. Run the steps in and out and hopefully you'll get some lubrication in where the shoulder of the bolt and the bushing runs against each other.
I did buy some new anti slip strip from Home Depot and insytalled it on each step
