Best way to check shock absorbers i have found is to push down on each corner of car , very quickly but with most of your weight , let car spring back into position , if car rises fast and dosn't bounce up and down more than once or twice your shockies are o.k , but if car keeps bouncing 3 or more time's they are no good and will need to be replaced .

sometimes the spring that surrounds shockie has worn rubbers these can emit noise also ,
mainly sqeaking but if either shockie or spring is able to hit car body due to perished rubbers then knocking noise will occur.
check also that you dont have a cracked spring , i have seen this also , remove tire and visually inspect.

hope this helps .. good luck

I'm having problem with my Toyota AE100 which when I drive, the rear suspension sounds like 'klak..klak'. For your info, I'm using a GAB adjustable suspension with 17 inch wheels. I'm trying to get rid of...


first of all, since you are using adjustable suspension you should make sure the spring is captive in the shock absorber. Lift the rear of the vehicle and support the car on the body, allowing the rear wheels to hang down. See if the spring can easily be moved. If it can. then likely the spring has sagged, or it is incorrect for the shock absorber. If not, while you are there check that the top hat of the strut is tight by lifting the wheel and strut assembly by hand. If you get any movement in the top of the strut, there will be a loud noise while going over bumps. Another area to check are the stabiliser arm/sway bar bushes. Mounted to the body you will see a bar that goes left to right, connecting to the struts with small link arms. Try to move this bar up and down against the body, paying attention to the rubber bushes where it meets the body. If there is movement in the bushes, there will be banging sounds when going over rough surfaces or bumps. Also check the small link arms for looseness or play.

2003 dodge neon engine noise, sounds like a diseal truck


If you mean it is really loud, you have a major exhaust leak. Did this start suddenly? Sometimes an exhaust problem is caused by hitting something underneath the car, like running over a speed bump or parking lot curb. Listen under the hood, then under the body of the car. You should be able to locate the source of the noise if it is an exhaust leak. You will probably have to get a service mechanic to fix it as it often requires welding.

Rear Suspension noise on 2001 Jeep Grand Cherokee V8


Check sway bar. On some models as suspension sags, sway bar outer ends will contact the body, leaving a mark or dent just above the end, causing a bang over bumps. Only way to correct this is to change springs or add a spring lift.
