problems with my new servo???

hi! so, I drive 88 g20 and recently my servo pump was smoked… (I turned off the original wave in front of the shovel… -would also be interested in how this can happen…) in any case I ordered extra powersteering fluid on kts-rat and poured it into the box… (atf oil – so automatic oil is not recommended to me…) my problem is that I no longer have the same power on the servo as before… despite entl airing etc. I can forget in the stand gas to steer the cart… with a bit of gas then as always… I want to know what you can do to help your crates… and if maybe someone has a similar problem as I do and knows what you can lead back to…
