Okay, so I have a 2010 SS (LS3) with only 11,000 miles on it. I had an dumb ass "incident" a couple weeks ago where my floor jack slipped off the front beam and it bent and nearly broke off one of the ports coming out of my steering rack. Yep....that was STUPID
. Anyway, no big deal, I bought an entire brand new GM steering rack off of ebay (from one of the GM parts dealerships), I was surprised it was only $250. Anyway, I installed it on the car with no issues. Added a little fluid, and drove it, figuring any air in the system would work itself out. Well, the steering wheel "shuddered" quite a bit while turning, which I figured was just air in the system, and it would eventually work its way out. A mechanic buddy suggested putting the front end up on jack stands, starting the car, and turn the steering wheel from lock-to-lock several times. I did that this morning, did about 10 cycles back and forth from lock-to-lock. The "shuddering" stopped, and I figured I was good-to-go. On my way into work, I noticed that above 2000 RPM, the steering seemed better, no shuddering, but still a little lagging. Below like 1500 RPM, it felt like I had NO power steering at all. Luckily, I'm running skinnies up front, so I could still get around alright. Sounds to me like a bad power steering pump now!!! I just can't figure out why the pump would be bad now. I never started the car after I broke the P/S line, replaced all the components, checked my fluid, and now it feels like the pump is shot!!! Only 11k miles on the car. I'm stumped!!! My buddy told me to check out the "Turn One" aftermarket pump....but holy crap.....$595!!! I think I'll just get an OEM replacement or something. Any ideas why the pump would be bad now, or anything else that might be causing my problems??? Thanks in advance for any advice.
