Rams are not rebuildable.

Actually I thought I needed to rebuild/replace mine and it turned out all it as is the pump as lo on fluid.
I went to the Farm and fleet and bought a 30cc cattle syringe and removed the pump from the mounts (really simple) and added fluid until it leched out the hole.cycled the top up and don a couple times and it works like new.
Just a thought before you invest.

Rebuild the pump yourself, not hard, not much too it.
Get new lines and cylinders. Use type F trans fluid.
I bench bled the system off the car, to ensure all was well before it was in the car an also easier to fill with no mess.

Thanks for the tips!!

If the lines are intact you can easily bleed the air out of the system in the car.
All you have to do is run the cylinders up and don until they extend and retract at the same time.

Agreed. But why do all that with old lines? I would replace them to save a problem down the road.
