2002 Olds Alero suspension noise
|
|
|
Creaking/popping noise from rear suspension at low speeds on smooth surfaces up and down low/high grades, No noise over bumps and struts are good. If I drive down a quiet street at 15-20 mph on smooth road I can duplicate the noises easily by sharply rocking the steering wheel back and forth (10:00-2:00). Sway bar links/bushings or something else perhaps? PS: strut mounts were replaced with struts about a year ago
Thanks

If you suspect sway bar or links causing noise, disconnect the links and tie up the bar. Drive to see if the noise is gone.

If something like that came into our shop and we suspected the sway bar bushings or links causing noise, that is what we would do first. If the noise didn't go away with the bar disconnected, then we'd start looking at other things like loose suspension components, loose hardware, shifting cradles, and anything out of the ordinary.
Of course, a visual and suspension steering inspection would be performed before we even started disconnecting any links.
You'll have to swing into your local repair shop to see what's going on.

Not entirely sure. Links and sway bar bushings are not very expensive. Shifting cradles are usually fixed by tightening mounting bolts unless there is a corrosion or threading problem. Really don't know what kind of price your looking at until the cause is identified. There also may be some technical service bulletins concerning your symptom the repair shop can look into.

upon inspection of rear sway bar, links, and bushings, tech found bushings very worn and about 1/4" of play when moving link back & forth near the frame area. Could this be the culprit for the popping/crunching noise? I ordered the bushings and will have them installed Saturday.

It's a possibility and it needs to be done anyway. Hopefully that resolves your problem. If it doesn't, at least you know the rear sway bar isn't the culprit.
Like written earlier, you can disconnect the sway bar and drive the vehicle. If you still hear the noise, then it is something other than the disconnected sway bar.

sorry for being redundant, but I'm a little concerned. If the struts are ok and the swaybar links are intact, what else might it be if I'm duplicating a bang or pop while intentionally swerving the car back & forth in residential neighborhoods? Again, the car drives perfect and noise free 40 mph and higher.
thanks

Why don't you just wait untill they replace the swaybar bushings.
If it don't fix the problem then ask questions.. lol

Could be anything that is loose back there. Maybe exhaust banging around from a broken hanger, something moving around in the trunk, loose suspension component causing the dead axle to shift around. Start with the obvious and go from there.
Even though the strut mounts where replaced, it probably wouldn't be a bad idea to check the strut mount nuts and the strut nut to be sure they are tight.

Well> I had my private tech replace the rear sway bar bushings and voila, noise free. Repair also taking load off struts and soaking up broken pavement nicely. To tell you the truth this 10 year old car drives and handles better than my '08 Honda Accord coupe. 4 Cyl engine is also quicker and more fuel efficient tha the Accord. Knock wood, So far this is a great looking and mechanically sound for a $3200 investment. Thank you all for your input and support!
