I would suggest you first clean the jack "post" when down with a cotton cloth and then apply a thin coat of silicon spay. Also do that with the 2 rears. Also check the hydraulic fluid level in the reservoir. If that is OK, but you have no record of the fluid being changed, then suggest you change it. This seems to be overlooked quite often. Nothing difficult here, but just be sure the new fluid level is set correctly and that you don't operate the jacks with the reservoir cover off. You should also look around for fluid leaks if the reservoir is low.
Suggest you also do a forum search re jack issues others have encountered. There is a a lot of good info here on this subject. It may be an electronic issue, but I would opt for the easiest path first. PLEASE let us know what you find out....thanks!
