Clunk over potholes

Phill_190 · 11th April 2017, 19:19

Hey,
My zt has started to make a very slight clunking over potholes that i never really noticed before. Also the steering feels a bit vague and twitchy over certain surfaces. What could this be? The drop links have been done. Also passed mot and tester said it all felt solid back in Feb.
Is this just a trait of the zt having firm suspension etc?
Cheers
Phill

Could be worth checking drop links again, mine were done a couple of months ago, after being changed in march last year. They were OEM ones from dmgrs too, but to be fair to mat he sent out a replacement set under warranty.
Mine is still a bit clunky over potholes though, although not as bad as it was before they were changed.

I will take it for a free suspension check tomorrow and see what they say.. its more the light vague sgeering thats off putting to be honest. The drop links were delphi I believe

Hi, hope it isn't what my mg zt failed its MOT on recently - a broken rear spring (as well as rotted lower mounting) - which came to a fairly hefty sum in the end..... but I imagine pot holes make everything travel more violently, so check springs, shock absorbers etc.
But I now note with the MG zt fixed that it steers a lot better and 'feels' right....

The top of the suspension bearing when worn can cause a CLUNK over pot holes.

jack it up and give your wheel a wiggle left and right if you hear a clunk could be tie rod inners or outers and wiggle top to bottom if it moves/clunks could be where the wishbone meets the hub sometimes just needs tightening up as these are murder for that also if your wheel moves left and right it could be the rubber bush the wishbone arm fits into as for roll bar linkages these can be felt by hand as iv replaced all these items in the last year lol
