Sounds very similar guys. Twitchy on the freeway and over steers easily. I would really like to get a good burn out and donut out of my system but since I can't saw the wheel it's very uncomfortable.
And yes, my PS pump is starting to whine also
It's a hydroboost pump that came on the LS engine, just not using hydroboost brakes. This blows, it's not a fun job working on this thing in the dirt and outside, so taking everything apart isn't something I look forward to.
Should I be able to move the BJ by hand? If I take the knuckles off, how much force does it take to rotate the BJs?
