I am guessing the steering rack is starting to go bad. That is quite expensive to fix. The whining noise is the rack sucking air due to the steering fluid has leaked out. You can check your power steering fluid level and add some with stop leak to see if that helps. The filler cap is at the rear of the engine on the passenger side and is quite hard to get to. Be sure to not reach down to remove the cap unless the engine is cool. There is a high risk of burning yourself on the exhaust manifold.

Sounds like a bad front wheel bearing but comes as a hub assembly

I've goy a 05 Buick LaCrosse CXL 3.8L that acts like its not getting any gas then will take off like it was floored.Idle at stop is erratic


You need to remove the air hose from the throttle body and get some throttle body cleaner and a tooth brush. My Lacrosse started to hesitate then lunge around 100k miles or so. Cleaning the throttle body completely resolved that issue. Get the cleaner and spray it in and use an old toothbruch to gently scrub the body and the plate. I would put a towel underneath the throttle body as plenty of black liquid is going to come out.

Bad cadillac converter


Sometimes you can tell that a converter is clogged because you don't go any faster when you push the gas pedal. Also, there usually is a noticeable drop in gas mileage associated with a clogged catalytic converter.------------------------------------------------------------------------------

Serpintine belt diagram 2005 buick lacrosse


If there is no decal under your hood somewhere, you can usually get them by wrapping the belt, first, around the crank pulley, and then work your way around, putting flat sides to flat pulleys, and ribs to ribs. There may be a couple of different ways to go, but you'll figure it out.
