Hi everyone. I have a 1998 bonneville SE that I love. I am the second owner and it has 82,000 miles on her. I have noticed over the last 20,0000 miles or so that the steering response on the car seems sluggish/loose with speeds over 65. It certainly is not very confidence-inspiring especially when driving on the interstate. I checked the tire pressures to rule that out and they are fine. I would love some ideas on what to check next. I am certainly not an expert on the steering components. Thank you all for your respones! Chad

Check the power streering fluid level. Also look to make certain the pump pulley is turning when the car is running. You might have belt that is slipping at higher RPM'*.

After you have ruled out any of he above, its time to inspect the entire front end and look for worn or damage parts.

So I checked several steering components tonight. The sway arm bushings appear to be in great shape. The struts seem to pass the "push" test. Is there any way to check to see if the tie-rod ends are good? Tire pressure is good. Steering fluid is good and there doesn't appear to be any major belt slippage, although I can't really guaranteed that. Any other suggestions? Thank you! Chad
