Hello electrotech
Thanks for the info
You were right on the money,the upper drive unit support
Bearing was missing half the ball bearings,iwas amazed that it didn't
Show any signs other than a hard plug in forward.
Thanks again.

hi pistolpeted I suggest that you replace the gearbox steering bearing as the that is what is cause of your fault so that is the bearing supporting gbox steer turntable when it is not serviceable it causes motor to pole when plugging usually determined by steering full left or right the fault will disappear good luck
