After months of driving off-road and having my running boards turned off, I decided it was time to clean them up and lubricate them. I spent the weekend detailing and waxing my truck (she loves being dirty...). Summers here in northern Nevada are dusty and autumn brings rain, snow and MUD. After turning the running boards on, they creaked but opened with no problem. I sprayed the hinge joints with WD40 and it has worked well. I will keep them auto deployed for a while to work in the lubrication and re-apply.
A fabulous vehicle both on- and off-road!! I love it! I will send some photos around soon.
