Just discovered my Happijac issue this afternoon. Mine are ratcheting like they are overloaded. I got the 2 rear jacks to work, I think. The fronts are 4500's. All are 2008 vintage with vertical motors. I used a 1/2" allen socket on a 1/2" drive ratchet and couldn't move them manually. Lever was in down position. So I cribbed up under the camper and used a car floor jack to lift one front jack off the ground. It still won't turn manually or engaged to the motor. The motor spins fine with the jack disengaged. Even tried a cheater bar a little bit. I took the motor covers off and all looks well. Still has a good bit of my white lithium grease on the gears.
The camper is under a Classic Accessories cover when not used. I keep small plastic buckets over the front jacks. Camper has not been used for over a year.
I thought there was a thread on here about rebuilding the jacks. Can anyone point me in the right direction?
Thanks in advance.
