i gotta clonk

[old codger]

i have an intermitant clonk on the offside front-i know its not the brakes,bottom ball joint or track rod end as these have been replaced.

The suspension leg looks fine as do the engine mounts & wishbones-no signs of wear or rubber bushes broken or cracked

Any ideas anyone?

anti roll bar drop link. most common failure on the 406.

about £15 for the part and two nuts to do the job.

[old codger]

Forget them-replaced them too.

[jameslxdt]

when does it occur, braking? over bumps? accelerating? changing direction?

[old codger]

Intermitant no set pattern to it.has happened on all of those occasions

[jameslxdt]

how many miles has it done?
i would suspect either lower engine mount or front anti-roll bar bushes

[old codger]

Too many miles i suspect-which first or how can i check the items you suspect?

if your engine mount looks like the one in this thread then thats the cause, as for the anti-roll bar bushes, you need to jack up one side at a time, though its the offside in question do this side first, take the wheel off and look at the bush thats wrapped around the anti-roll bar, if its really badly cracked or torn then this is the problem

is it a saloon or estate?
the engine mount is far more common than the bushes

[old codger]

All the bushes look fine-solid,no cracks,breaks or any signs of movement or seperation-even lifted it on trolley jack & dropped it to see if owt happens.

Only thing it seems to stop if its raining or roads are wet.
Wishbones seem fine too.

saloon-D8-mind you it is the ame sort of clonk my old 405 made when wishbone was on the way out

[old codger]

1 thing i did think of was the spring on the mcpherson strut moving on the bottom cup-possible do you think?

Top Strut bearing, Mines just gone HDI T Reg, 99 110 Estate, Clunk when your driving at sortof random times, there about £30 from a Motor trade place or yhou can get one from the scrappy.

Its the bit on the top under the metal bit with 3 bolts that mounts the top of the suspension and alows it to turn smothly. when it clunks you may find the steering wheel is slightly out of center, clucnk and its stratight.
