Repairing an Autohelm Drive Unit

Wondering if anyone has had experience in repairing an Autohelm linear drive unit. This is part of a Autohelm 5000 sail mounted below deck and it is the electrical "type 1" push / pull unit. Picture is below.

When you pull and push the ram unit you hear a rumbling noise. The local Raymarine dealer is saying it's a writeoff; apparently the ram is a worm type full of ball bearings and once you put it apart all the ball bearings fall out and you can never get it back in.

Any advice / comments appreciated.
