There is a knock going over certain bumps.

So I've changed ball joints, drop links front and rear, and just tonight, the wish bones. But still it persists.

Can't quite tell what side it's coming from unfortunately so everything has just got changed.

Anyone any thoughts as to what's next?

Ah dear, thatll be some handling in the drive way. Last car I'd to remove shocks on was my 172, so much easier

Top mounts and bearings changed. Struts seem to behave OK when I had them out, weren't bouncy and returned slowly to the top. Same knock is still there..any other suggestions?

Are you able to isolate the knock to a given side? I.e. going over a bump/dip on one side only?
Even though you've depressed the dampers and they return fine (no sticking or squelching) - it could still be a dodgy damper.

Chasing front knocks is hateful! Can be anything from pads rattling in the carriers to even a mid-section exhaust hanger being broken and causing the exhaust to knock and resonate up. Anyone over on VWROC had similar issues?

Yea, googling dodgy shocks is useless, there was no oil or anything so unsure what else to look for etc yea checked all the exhaust stuff too, all tight.

Sounded like it was upper passenger side, but generally inconclusive. Already spent a fortune so trying it bit by bit, just a shame if i chsnge shocks ive to take it all apart again. Passed MOT last week too, though im unsure how thorough the test was tbh
ARB bushes?
Haven't looked at them yet tbh, sounds like it's coming from the extremities, but they could well be changed yet lol

Negative, I've turned the radio up for now.
I took mine to magowns in carrick to test the shocks and they were fine, so I've lost interest for a while. Anything else I think is potentially above my station

Rear bush in the lower front arms? These are hectic for falling out of Polo's, Fabia's etc. Lad in work had the same in his Golf R.

I've had to replace them on my wife's 2017 Polo and my mum's 2015 Fabia.

You didnt happen to leave the wee plastic ventilation box hanging loose that comes from the gearbox? I thought I had a suspension knock for a long time and it was that rattling every so often.

I'm gonna fire it over the pit this weekend and have a good look. Haven't done any work near the gearbox so not even sure what it'd look like.

Not sure I'll find anything since it only happens on a sharp bump and I'll not be able to replicate it šŸ˜–

It's attached round the battery tray area, small black box about the size of a couple of packs of cigarettes with a tube going in to it.

Just had it over the pit, took the drop links off and tried the ARB, doesn't seem like there's any okay in that either.

At this stage I'm at a huge loss as to what else it could be that I can check

Nope to both (that I can feel in my limited know how)
Only thing I can think of is actually the shocks, could they be topping out on the rebound or something? When I pushed them in off the car they returned slowly to the top so I'm unsure again

Whereabouts are you? Might be interesting to compare? Then if the worst happens just set them both on fire

Could it be gearbox or engine mounts? Hard to identify I guess, but worth looking into.

There wasn't any movement when I changed the wishbones so wouldn't think it, having said that, it's going to a mechanic tomorrow to see what he thinks, I'll report back

I doubt it'll help anyone else but problem solved
The ball joints that went in were sh1t3, replaced them ...again, problem solved.

Then came the polava of getting alignment done, but finally, wheels be straight and knocks be gone!
