steering pump issues

[Advanced]

Hi, I recently put my impreza 2.0 sport into the garage as the pump fly wheel had a wobble and in full lock it whined. the other issue was moving it for the first time every time the engine was started the steering would loosen off from the normal.

I would qualify the steering was never heavy.

The pump was taken off by the garage and the bearings replaced. however the garage has refitted it and the steering is overly heavy. the garage have spent time bleeding the system and trying different ways to try and loosen the steering.

Can any one suggest what the issue with could be.

as stated the steering was not heavy before the pump was reconditioned
