Is your Chevy Impala or Monte Carlo's power steering whining, leaking, or getting hard to turn? This Detroit Axle replacement pump is a complete, ready-to-install unit. It fits 2006-2011 Chevrolet Impala and 2006-2007 Monte Carlo with the 3.5L or 3.9L V6 engine. The pump comes fully assembled with the pulley already pressed on and the reservoir attached – that saves you a ton of time and hassle. It's built to meet or exceed OEM specs, so you get a proper fit and reliable performance. Installation is straightforward if you're mechanically inclined (remember to bleed the air from the system afterwards). Once it's in, you should notice smoother, quieter steering without leaks. Detroit Axle tests these pumps for pressure, flow, and noise before they ship, and they back it with a 10-year warranty for peace of mind. If you're doing the job yourself or having a shop do it, this is a quality aftermarket pump that won't let you down.
