How do I troubleshoot a noisy suspension?

Answer by  Amber40 (24961)

Well unless you know exactly what is making noise then you will need to crawl under your car and inspect the whole suspension. Looks for anything that is damaged. Check to make sure all hardware is tight. Lubricate any components that need lubricated. Otherwise look online to see if other people have had similar issues with you type of car.

Rattling of the suspension can usually be fixed simply by re-torquing the nuts at the top of the strut towers under the hood and in the trunk. The chassis should be lubed along with every oil change and worn out bushings should be replaced to quiet the operation and prevent wear to the system.

One way you can check is to climb under it and look for any broken or loose components.Lubricate all suspension bushings. A whistling and winding sound coming from the lower suspension it is your wheel bearings and they need replaced.

First try greasing the suspension. Then take a look at any rubber bushings like on the sway bars or whatnot and see if they're dry. If so, replace them. If all else fails, take it to your dealership and have them look at it.

The noise is because of bushings or lack thereof in upper and lower control arms. It is because of two metals banging together. Bushings should be replaced. Check for shocks control,whether they are allowing to bounce else replace the shocks control. If you are hearing metallic whistling or winding sound from lower suspension,then wheel bearings are worn, need to replace.

Get under the vehicle and look for loose or broken components. Then lubricate all your suspension bushings. You may need to cycle the suspension to narrow down the problem.
