My pump is making a whining sound, similar to a manual tranny in reverse, now that my hydroboost is installed. My pump is leaking from the front, so I'm going to get the rebuild kit this weekend. Should I do the WTO more volume mod while I'm rebuilding it? The brakes feel fine, and the steering is fine, except when turning at low RPM's, it's a little tough. 31" tires, no lift.
