Peugeot 207 rear end clunk - what to check?

[randomandy]

My 2007 Peugeot 207 has a clunk / knocking noise that seems to be most prevalent when the car goes through a pot hole or over a large bump in the road. Trying to get everything sorted prior to MOT next week. My current list of things to take a look at to see if they are the cause of the problem are:

• Broken spring
• Shock absorber
• Worn bushes

Anything else I need to look at?

It might be worth checking the exhaust and it's hangers. Does the noise appear to be from any particular area? Front, rear, underneath?

[randomandy]

I've given the exhaust a good wiggle from underneath and it seems pretty solid. From what I can tell, whilst driving, the noise seems to come from underneath at the rear.

My plan is to get it up on axle stands over the weekend and have a good poke and prod around. Just want to make sure I don't miss anything.

Try lifting the car a few inches under each rear spring pan/shocker mount and "bounce" the rear. See if that makes the noise. It just replicates the twist in the car as you hit bumps. After that it is inspection and a pry bar. A broken spring should be easy to see as would worn shocker bushes. Worn arm bushes are more difficult to spot but might show up as you jack each wheel up for the bounce test. Make sure not to work under an unsupported car and you should be able to spot obvious things.

If its front strut area id check to see if the front leg hasnt punch a hloe through the top wing housing

If its front strut area id check to see if the front leg hasnt punch a hole through the top wing housing
Also lower ball joints and all the pinch blotls that hold them in place id even check the brake caliper, droplinks top tie rod even the cv joints on the driveshafts.

If you are going to use axle stands don't support the rear suspension. Support the body/chassis somewhere solid and secure. This will allow you to lever the suspension arms and/or use a jack to try for movement in the rear arms/mounts.

On my 207 the Spare wheel inside the well makes a noise I was sure was suspension related.

I have had a poke and a prod about whilst I have had the back end off the ground changing an ABS sensor and the springs look OK. The rubber gaiter on one of the rear shocks has completely detached at so I imagine the inside of it is completely done for.

New ones arriving tomorrow, hopefully they don't put up too much of a fight - how hard can one bolt top and bottom be ?

Have got the rusty bottom bolts to finally move so that I can swap the shock absorbers. Should the rubber gaiter be fastened to the top of the shock so that the piston rod isn't visible?

Hi Marc,

What is the item marked "3"? When I replaced the shocks that didn't look to be a removable part although that could just be the fact that it is rusted in place. Had to get bolt "2" out using the E-16 socket and a piece of scaffold to extend the length of my ratchet handle - maybe Santa will bring be an impact wrench for Christmas!

I'm not sure the shocks are setup entirely correctly as there appears to be quite a big gap between the top of the tyre and the wheel arch. Anyhow, the MOT examiner didn't find anything to complain about other than a front wheel bearing that I knew needed replacing. I left the replacement ones in the boot as I don't have a press to be able to do them myself!

I recently changed a pair of rear shocks, I tie wrapped the gaiter to the shocker tube just to keep it double secure agasint it coming free at some point.

I’ve only just seen your question 2 posts above.

Item 3 is a securing nut, but is not shown as being fitted on your vehicle, so you may have a different type of fixing if it is not there.

What was the out come ?
