"Clonk......?"

**WedWon** · 22nd July 2009, 02:18 PM

Doesn't seem to be anything loose inside rear door

Have you tried bouncing up and down on the back of the car while the car is parked?
If it is a shock it should cause it to "clonk"

Clonk not evident when bouncing on rear bumper

had the same on the wekend, checked the radius arm ends and the nut on one side was on its last thread....phew that was close!!

PS they clonk from factory don't they?

Will check radius arm tonight...thanks for the warning

I thought the "s" model was "clonk-free"

well if its happening down pot holes i would go bushes or shock/shock bushes

Thats what you'd expect but maybe its something "clonking" when body flexes?

Who Knows? Maybe I will by Sunday!!

My 93 200tdi d1 has the same Clunk. Been over everything (as has my mechanic) and still cant find t.
If you manage to locate it and tell us all you will be in my thoughts for eternity!!!

I'm up for a 6 pack!
My guess is the A-frame ball joint.
pm me and I will give you my delivery address for the 6 pack of Courvoisier Cognac bottles!

One more go,
Loose brake caliper?

Hi,

I'd be revisiting the ball joint. They don't need much slop to start making a lot of noise.

It could also be play in the conical hole it attaches to the diff housing through. This can wear also, and it gets progressively worse the more the joint can work it. Take the split pin out and see how easy it is to turn the nut. It shouldn't want to tighten any more.

Don't know if D1's have the Boge load leveller. If so, it could be the ball joint at either end.

cheers, DL

Get a helper with big muscles. Put the car in gear, handbrake off and get your blonde assistant to rock it backwards and forwards while you examine, watch, pry, and feel every bush and joint on the rocket.

My bet's the a frame ball joint, but if that's all clear, get the blonde assistant to attempt to move the car from the front, pulling/pushing at right angles to the vehicle axis (attempting to twist the car). As before, look, feel and listen to each bush and joint.

I reckon this is the only way to check out where bush and joint wear is located - visuals are sometimes inconclusive.

The assistant will be exhausted by the time your examination ends - have some refreshment handy.

Or take it to the local Pedders store and pay them $14.00 to do it for you

mate might be simple ....but do you have a rear step?

cheers

**WedWon** · 18th August 2009, 02:08 PM

Right then

Definately no play on the Ball joint

No loose brake caliper

No rear step

No excessivly worn suspension bushes

But.......

Did find that the whole rear left quarter panel seems to "boom" and reverberate when knocked (the right side seems to be braced more with the filler cap coming through it)

Could this be the mysterious "clonk"? I have previously had to re-Sikaflex the roof panel because it would "boom" when off road. Will dismantle the panel next weekend and see about glueing it back together.

Anybody else had this occur? Anybody else with the mysterious "clonk" want to check their panel too?

Did anybody sugget that in the thread (for a six pack)?

Will keep you posted

Cheers
