Today I will play "Hunt the Clunk"

23 Mar 2019, 8:28am
Occasionally and intermittently* I get a clunk when I brake hard and then accelerate. This mostly happens when Approaching and then exiting a corner but that is because that it when I brake and then accelerate. It does sometime happen when I brake and then accelerate in a straight line though.

Hard to work out where the clunk comes from but I think it is the back of the car. Unfortunately I have been unable to work out how to replicate the clunk in a test environment so cannot be sure. It just happens sometimes and never gives any warning so I am not really listening for it to determine exactly where it come from.

I am starting by jacking the back of the car up and seeing if anything seems loose or clunky, especially around the brakes. I will then do the same up the front.

Any other suggestions welcome.

*Never words that make finding a fault easy.

Handbrake or brake hose 'slapping' on the body?
Tailpipe moving?
Springs moving in their cups? Install rubbers.

Set up one of those GoPro cameras, to try and capture some live action footage.

I had a similar problem on my sierra based Severn. The floating cones on the wheel nuts had seized solid stopping the bolts from being fully tightened result clunking sound on acceleration and deceleration new nuts fixed the problem. A possibility?

Well the first search has revealed one pipe not clipped into its holder but nothing else.

Wheels are on spinners and tight.

All suspension bolts checked and tight.

But guess what?

When I chucked the lump hammer back into the boot after tightening the wheels back on there was a very familiar clunk!

Possibly the hammer moving around in the boot?

I have removed the hammer and am going for a quick spin.

Check the large nut behind the steering wheel:biggrin::biggrin:


I had an annoying nagging whine in my car, left the wife at home and it stopped.

Removed the loose hammer from the boot and the mystery clunk has gone*

*for the moment

And why exactly did you have a lump hammer in the boot?

What- loss of??? :peep:

A hammer is required to remove spinners on wire wheels. Preferably copper faced but interposing a piece of wood whilst using a lump hammer gets my vote as well.

Also a good alternative to my axe during 'conversations'
