steering and hi/lo issue

[T2693]

Well since I've been working on the custom truck I've been toying around with my stocker and it seems to be pulling right hard now since I rebuilt it.

Any idea why? I know the stock servo saver sucks compared to the UE and other versions so any why to adjust this?

Also I noticed when I try to engage low gear it won't engage so I have to return to high for it to run. How should this be corrected?
