Hello Folks,

I had to replace the water pump on my 02 Trailblazer. I got everything back together, and I had the classic dirty throttle body symptoms after having the battery disconnected - it would almost stall, rpms around 300 after turning on A/C or defrost. So I removed and cleaned the throttle body and replaced plugs while I had the air filter off.

I got all of that done, and I go to drive it around for a few miles for quality assurance purposes...and...I back it out of the driveway and hear this screeching scraping metal on metal sound when I brake. I drive around a bit and find that I hear the same sound when turning sharp. This is not a low rumbly wheel bearing sound... It kind of sounds like a rust corroded bolt when you first crack it and start to loosen it eeeeechhhhhh eeeechhhhhhh.

It only occurrs for the duration of time that I'm braking to a stop or am turning sharply at a low speed.

Any ideas folks? Does this sound like a CV joint issue? Could it be a result of all of the coolant leaking out at the water pump gasket and soaking everything below it in bright green love?

I'm at a loss, and I'm unable to recreate it by bouncing the vehicle up and down or back and forth.

Any insight anyone can provide is appreciated!

Thanks,
Rob

Not yet, I'll jack it up tomorrow and do that. I ran out of daylight tonight. I've owned a few lemons that needed brakes and have done a few brake jobs, and I'd be surprised if it's pads or rotors.. Because I've just never heard brakes make this noise, but I could certainly be wrong and I'll investigate in the daylight. Thank you for the reply. Any other ideas welcome.
