Knocking from front suspension

There is a hollow knock from my suspension, its ok over speed bumps ( ie, wheel going up), but if I were to drive over a dip in the road or pothole/grid (ie, wheel going down), its then that you hear the knock.

iam wondering if it is either top mounts, drop links, or ARB bushes, and are these jobs easy to tackle as I'd be doing it myself.

iam not bad with spanner, but if it needs specialist tools then iam out...


thanks in advance

One of the two coupling bars needs to be replaced.
Normal issue...(try the search funcion. Must be here a few times..)
 
knocking

I had the exact same thisng with my 1.4tdi, it knocked going over bad bumps or speedbumps but not normal traveling along the road.

it turned out to be the anti roll bar (old design with plastic collars) which had shifted to the offside by 2 or 3 inches due to the corosion of the arb and splitting of the retaining collar, the roll bar shifting was making the curve in the roll bar where it connects to the droplink hit the aluminium spaceframe and i could see where it had bashed the spaceframe and marked it, i slackened off both sides of the roll bar, moved it back across, replaced the droplinks (£15 delivered for two on ebay) replaced the arb bushes from vw dealers (£5 for both), clamped it all back up in the right position and used 2x jubilee clips to help keep the arb in the correct position, i would have liked to have changed the arb to the new style bar but cant afford it at the moment.

this was done about 5 weeks ago now and it seems ok with no knocking however i feel it may return until the arb is swapped out for the new style one but fingers crossed it may last??

You had exactly the opposit. (if no sound on rough road but only on speed bumps)
Read his post:

That's why I say I know what it is and is the the coupling bar. ;)
It makes sound on craggy roads (always around the central position of the car when left to right when landing gear shock strut compression changes from one to the other side.

But you are right, the antirollbar bearing can make a sound like this.

knocking

i didnt know what it was at the time that was causing the knocking, i thought it was the droplinks but it turned out not to be, i only wanted to add my experience into the running for consideration by the original poster as until you get under the car it can be something totaly different as i found out and certanly worth checking for anyone removing the wheels to investigate a knocking noise from the front.
