Rear Knocking

[mervs4]

Hi I'm a new member with a mk2 c5 hdi

Over small bumps I can hear a knocking noise from the o/a rear

I think it is the droplink as it similar to The noise I had with a peaugeot 407

Also I cannot find any illustration to show the location of the link

Any hp would be appreciated

There isnt any droplinks on the rear of a c5 or springs or shockers. If its not a lose brake pads the its probally your rear trailing arm bearing.

thanks coastline taxis for your reply,however my c5 is hydroactive and it has rear shocks with spheres attached and short droplinks.

the sound is like the shock is loose but I have checked and all appears normal.also I have replaced the offside droplink.

can anyone help please

Nope there hydraulic rams you have fitted to them. you wont find your knocking till you remove the rear trailing arm. then take the bearings out and theyl either be disintegrated or dryed out. unless its a mk3 c5 but your posting does say mk2 and the fact you have sphere,s fitted rules out shockers,spring and drop links on the rear

you have done a check for the daft stuff? loose spare wheel? clanging exhaust?  just a thought.
