Knocking sound when going over bumpy roads

(1/3) > >>

Hi All,

I am hoping this turns out to be nothing with the previous issue I had with my car but I have a knocking sound whenever I go over bumps or uneven roads. It initially started happening a few days ago and only when the drivers rear wheel went over bumps. It does now seem to be when any wheels goes over a bump or basically when the car is moving about. The sound however still seems to be coming from the drivers rear side around the boot. Also I have noticed today when turning the wheel going slow the car sometimes give like a creak noise as though something is cracking or snapping. The car once going drives totally fine and I do not see any issues so not sure what this is if anything.

It did all start happening when I was stuck in a multistorey car park a few days ago and kept having to break on downward hills and use handbrake etc if that helps.

Might sound stupid but one thing I have not done is check there is nothing  lose in the boot that is knocking about but I did the other day remove any lose heavy thing like tools etc so can only think if it is something knocking about in the boot it may be the spare tyre etc.

Any ideas on this appreciated as I know there is not enough info to diagnose but maybe some ideas on what back there it could be  :confused:

My first move and double checking the back seat fixings are clicked in properly and boot items are where they should be.

Next would be to check your coil springs to see if any have snapped - cold weather and coil springs don't mix!

Yeah good point, if I get a chance before it gets dark this week I am going to check in everywhere where the spare wheel is, will remove everything from the boot and check like you say all the seat fixings.

In terms of checking the coil springs I presume they are visible under the arch and can check easily that way with a torch?

doylebros:
Torch is handy but feeling with your fingers for a crack or part missing is best. :happy2:

irish_ram:
Nice one, will do.

I am feeling another into the garage and AA Warranty claim coming but this one may not be as easy to claim as my initial issue I had  :sick:

I will check what I can this week but I am no expert
