When drive is tucked in, its tight.. When I trim it out, it hesitates for a second then moves... If I stop it I can move the drive in and out about an inch or so... no leaks.. plenty of fluid. ran drive in and out many times. thinking it was air in the lines... Where do I look next. Thanks Scott

not knowing trim cylinders but having rebuilt more shocks than I can count it does sound like air

I agree... It sounds like you have air in the system.

I thought by running the pump up and down I could get rid of the air..Do I have to crack the line or whats the process??

The pump should self bleed by running it up and down. Do you have enough fluid in your pump reservoir?
