Don’t ignore a loud knocking noise!

When you hear a knocking noise when going over bumps it is easy to assume that you can wait to get it taken care of.  For the most part that’s true.  A bad shock or a bad sway bar link will usually just make more and more noise until you’re forced to replace it.

The first thing you have to do is identify what part is causing the noise. Unfortunately this can be a bit of a choir. If you look at the suspension and there are some obvious parts that are missing bushings or not in their brackets, all you have to do is replace the part.

Don’t procrastinate if you see some bushing that are missing! A part that is hitting metal on metal will eventually damage the bracket that is holding the part. The picture is of a shock that elongated the hole it went through.

What if its not obvious whats making noise?

Start by identifying when you hear the noise. Does the knocking only happen when going over bumps or when you’re driving down a bumpy road? Then try duplicating the noise while the car is still. Joust the car up and down to see if you can hear the knocking. If you can have someone get under the car to see where the noise is coming from.

Does the knocking noise only happen when going over bumps?

Most of the time this means that your shocks or struts are making the noise. This isn’t always the case but the majority of the time its true.

Does the knocking noise only happen when driving on a bump road?
