Sticky tow bar arms?
DarreI,.....
I have the same towbar, with the same- but worse- problem. I'm in the process of rebuilding it as we speak.
Mine reached the point a couple of months ago where the arms were actually frozen in the out and locked position. That made hook-up and detach very tricky and inconvenient processes. I spoke with a tech at Roadmaster, concerned that one or both inner arms had gotten slightly bent. But he said no, they've seen this in some older bars, it's just excessive carbon buildup inside, on and around all the bushings.
So I bought the bushing/rebuild kits to thoroughly rebuild the whole assembly. I shot a lot of PB into every place I could access over the course of three days, and then still had to really whale on things to break the inner bars loose and drive them out.
Folks at Roadmaster support were extremely helpful. Their instruction was to thoroughly clean the parts of buildup, then thoroughly clean off all cleaning solvent, using Simple Green or equivalent. Let parts completely dry and reassemble using lots of silicon dry lube spray.
I'm now at the reassembly point. All parts are clean as a whistle. If I bother to repaint a couple of small parts- and buy a new set of decals somewhere- my towbar will look brand new! I'll let you know how it works.
