Happijac slow leg

One of my motors is faster than the others so lowering it I will see one leg up in the air and have to compensate.
Defect or other?
After looking through threads I expect some dumb answers…. I know Happijac's are not known for quality, see other post for comments or to make comments about the quality, please.
I am looking for real solutions, not opinions of quality.

model #182522

Fiberglass camper so camper does not creak, flex or let me know until I physically see it, but can't be good for camper in the long run.
  • Mine are the same way. Apparently the motors do not produce enough torque to remain constant speed devices. Varying drags of the gears, leg friction, and jack loads cause the motors to run at different speeds. I just keep an eye on the front two jacks to see that they are about at equal extension and adjust as necessary. Then I adjust the rear jacks before continuing the raising or lowering process. I accept it as part of the jacking procedure.
