Question about 2003 Buick Century

1 Answer

Draining of the rack and power steering

I topped off the power steering fluid in May of my 2003 Buick Century that has 82,000 miles on it. Since then there is a noisy low moaning sound when turning 90 degree corners. Now I am wondering if the fluid was too old (it was in an old container that has been sitting around in the garage for a long time) or if possibly someone could have even put old brake fluid in that container.

I have taken some of the dark fluid out and have put new in with a baster, but the noise persists. What is the best way to drain the rack and the power steering so I can get all of the old out of there and put new in?

The best way is with a automotive suction gun (about $6), drain the reservoir and then refill until the fluid is clear, but from past years of many such noise concerns coming through the shop u will end up replacing the power steering pump.

Worn Steering Rack

That is what happens when you do not change the
power steering fluid every 30,000 miles

Same 30,000 fluid change for all transmissions
That will be the next thing to fail

Hi, it could be a wheel bearing. if you turn left and you hear it it will be your right front bearing and visa-versa. could be the power steering belt that needs replacing, good luck with it.

My 98 Buick Le Sabre's power steering stopped working. Car ran okay and was able to get to gas station. My car is now at 64,000 miles exactly when a clunking noise first happened, then a whining sound...


You maybe blew a hose, did you notice power steering fluid running on the ground? Did you check the fluid level, did the belt come off? You may have to have it towed to a shop, there could be a problem with the rack and pinion.

POWER STEERING


First off, verify that the power steering reservoir has the right amount of fluid and that it looks clean (not dirty brown or black). If so, try burping the reservoir to get any air out. Just start the car with the cap off and turn the wheel lock to lock, back and forth several times. This will force any air out of the system. If the fluid is low, top it off and take a drive to see if it's cured. If the fluid is filthy, use a turkey baster to **** out as much as you can, refill it with new fluid, burp the system again to circulate the fluid, and repeat the drain and refill procedure - do it a few times to try and get as much of the old stuff out as you can.

If you still have a problem, you should inspect (or have inspected) the rack and pinion, power steering pump and pressure lines, and also the bushings in your front suspension, as well as the inner and outer tie rods - any of those could cause the problem you're having.
