Company has two 1970 something Freuhauf trailers extendable high trailers .We will slide them 5 times in a week then go 5 months before they get extended .
I have used grease which helps but after a when the dust , dirt and what ever is kicked up turns it in to a goo that is nearly as bad as leaving dry .
I have tried spray Dry lube , Good for a couple times then back to the same old stuff .
I am open to any ideas at this point . Just getting tired of having to do this ....
