'93 Bonn. SE Lower Control Arm, Front, Right Side.

1993 PONTIAC BONNEVILLE

I have a '93 Bonneville SE. 110,000, V6 3.8 liter. This car is driven by my wife and we have had it for 2 years now. She came in the other day complaining about a low freq noise coming from the front end whenever she hits a bump.

I drove the car and confirmed the noise. Also heard what sounded like nuts and bolts ratteling when bumps were crossed. Looked and discovered that the sway bar linkages were missing the insulators. Both sides. I changed those out without any problems.

Low freq rumble noise is still there when you hit a bump. Not as bad, but is still there.

I suspect that the lower control arm bushings are extremely worn and making the noise we are hearing. I would like to replace them but am reluctant to go through the entire procedure as outlined in my repair manual.

What I would like to know is; if I undo the bolts holding the lower control arm to the frame, is there enough play to push it up/or down just far enough to slip in the new bushings?

Thanks a lot for any help you can offer.

Layers n layers of electronic is what make 2000 & up car runs smoother & effiecent than yesterday's car.
U must fix the misfire problem 1st. Ur O2 sensor sensing too much fuel thats why is shown a code. It is doin its job. Crawling all over ur car with uptodate equipment, knowledge is what it takes to pin point a problem. In the worse senario. It could be just a bad grd wire to the injectors or a short which take 5 minutes to fix. But it might take a mechanic 1/2 a day of inductive & deducive logic to figure it out. If u think he'll do that for free. He'll probably say no & rather do brake jobs which make more money.
