Slow retracting HWH levelers
The front passenger leveling jack has always be slow. I did replace all of the springs to the new type which did help but front passenger jack was still slow. It was necessary to use a old wooden handle type army folding shovel as a pry bar to assist the jack. My HWH manuals said lubrication of the jacks was not recommended. Therefore I was reluctant to use any on the jacks other than wiping them down.
Later I tried WD40 but it did not help and I did not like the idea of using transmission oil because of the oily residue.
Today I grabbed a spray can of Dupont Silicon and Telfon spray. I sprayed the slow jack and wiped in down. After the jack was sprayed it OPERATED NORMALLY. I sprayed all of the other jacks and they all retract faster.
I threw some fine sandy dirt on the sprayed shaft and the Dupont spray does not seem to attract dirt like oils would.
I was pleasenty suprised with the results and have added the spray to my maintenance items.
