2000 Pontiac Grand Am Stiff Power Steering At Low Speeds

Dave’s question:

“The power steering on my 2000 Pontiac Grand Am isn’t giving much power at low speeds. At high speeds it works fine. I changed out the power steering pump with a rebuilt unit, but it still doesn’t feel right to me.”


You’ve definitely got a flow problem in the power steering system. Either that rebuilt pump wasn’t rebuilt correctly, or the rack and pinion has sticky valves inside it. The easiest thing is to try a brand new pump instead of a rebuilt unit, as they are pretty easy to replace. I’ve seen that fix a problem like yours many times. But if that doesn’t do the trick, then here’s a trick of my own. Get some good solvent (like Sea Foam fuel injector cleaner) and put two to three ounces of the stuff into the power steering reservoir. Then drive it around a couple hours. If the valves are sticking on the power steering rack, that can often free them up. It’s worth a try BECAUSE replacing the steering rack is a pretty expensive job (and if you try a rebuilt rack instead of a new one to save money you could end up being burned as they often don’t have a great track record rebuilding the racks.)
