Question about 2006 Chevrolet Cobalt

4 Answers

I have an 06 Cobalt LS with a very annoying knocking sound coming from the front end. Someone told me it was the stabliizer bar links. I thought it was a strut problem because of the wet marks around both struts, but I did the famous bounce test ans the car comes to rest almost instantly. I was also told it could be LCA bushings. Now I notices inside wear, drivers side. HELP!

It is most likely the control arm bushings. These are notorious for going out on Cobalts. I have had mine replaced twice.

The control arms on both the driver and passenger side have rubber bushings which probably deteriorated. This is causing metal to hit metal when the car goes over bumps.

The bushings themselves are relatively inexpensive; you can most likely pick them up at a dealership for under $40. The only issue is installing them. You have to use a hydraulic press to press the old bushings out and press the new bushings in. This isn't difficult, but you need the equipment.

LCA rear bushing let go.Mine were done twice by the dealer on extended warranty. I did the driver's side this morning in the driveway myself. $160 at PEP Boys. My symptoms were: knocking at low speeds, like in a parking lot.

If the wet marks are oil,the struts on both sides should be changed. Slide the plastic dust covers up, and look on the top of the struts,the best you can.
The bounce test will not work on struts, because of the spring rates involved.
Also,you could have worn strut bearings,on the top of them,that makes a noise and also causes alignment issues,thus tire wear.
Check out any stabilizer links etc,they may be worn but not causing a problem

Wheel bearing? If you turn left and it gets louder. It is the right wheel bearing. And vice versa.

If the noise is coming from the front end, it could be a a CV joint, sway bar end link, ball joint. A mechanic needs to take it for a test drive to diagnose it properly.

Symptoms: rattling noise coming from front end of 98 explorer, pulls at the least little bumps, eats up front tires like crazy. Doesn't feel safe driving. What I've been told already: upper and lower...


definitely sounds like a ball joint problem, bushings would not cause it to chew up tires a worn moving mechanical part would such as steering components,wheel bearings,ball joints, and believe it or not shock absorbers

Knocking and rumbling sound from front end when driving on bumpy street


There are a number of things which could cause the sounds that you are describing. I could be a worn ball joint, damage to the strut assembly or sway bar links. Your car is not a very old car so I would look at the sway bar links first. You would have to jack the vehicle to check all of the things I mentioned, and maybe go under the car.

there are many possibilties. Sway bar, sway busings, shock, tire, something in the brake pad, wheel bearing, the list goes on and on. Best bet is to let someone qualified to take a look and determin what's wrong before hundereds of dollars are spent without the cause being fixed.
