just drive up to mark he will sort it for you.

 

Mate...he's worth the drive! I drove all the way up (and back!) from Reigate on Saturday for him to change my steering rack. He had it whipped in and out in under an hour and tracked within the hour! It might have cost 3/4 tank of fuel and nearly 8 hours of driving, but it was still waaaaaaay cheaper than having it done locally or by K-tec. You could probably factor in a night in a travel lodge and dinner for just over an hours worth of labour from most indies.

 

Sent you a PM mate

 

Hello Jaffa, I feel your pain as I'm in the same place as you. I've had the same stuff replaced and my noise still remains. It's like a single solid knock/thud. It only happens when hitting speed bumps and pot holes with a single thud each time. Mine is back in again soon fir some more fault finding. They say the problem is when it's on the ramp they cant make the thud happen, as they can't produce the same force as the weight of the car on the road. Sorry this is no help but I'm feeling your pain.

 

Long shot but have you checked the coil springs??!

 

Top mount

 

Not that much of a longshot mate. Mine started knocking and first thing I checked was the spring and it had snapped so I used it as an excuse to order some cooksports.

 

I have more of a squeak than a.knock, but my problem is the exhaust heat shield under the chassis. Worth checking for movement

 

I have the exact same issue, its a knocking sound and it appears to come from the drivers side, it has been into Ktec and they replaced the top mount as the wheel had some play but that hasn't got rid of the knocking sound. I have had it for a while now, the sound hasn't got worse but my steering has got a little heavy and it struggles to self centre. Im guessing that's the hub bearings? Ktec said that the problem with the rattle was a worn steering rack but I got a quote for a grand to replace it and they weren't sure if this was 100% the issue.

Like you the noise cannot be replicated once the car is on the stands, its only when its driving.

 

I had a replacement steering rack under warranty and it hasn't cured it. I'm sure I read somewhere that the subframe can come loose?

 

I'm having this too. When I bang the top(front) of the tyre with it on the deck it rattles. If I do the same with it jacked up it doesn't. It clearly happens under load, as it does when im driving going over little bumps. I've just replaced the drop link, I've had new brakes fitted so they're not loose, I've had the steering rack bush replaced and the steering is tight as and the subframe was refit so no looseness there.

Can the top mount really cause this?

 

I had my top mount replaced, it fixed the slight play in my wheel but the rattle remains

 

Check the front springs to make sure they're not broken

 

I had a 1.9dci that knocked from the passenger side. It was the steering rack bush that had gone. Check for up & down movement in the rack ends.

I also had a knock on my cup before I installed cooksport springs. At the same time I stripped the top mounts cleaned & re-greased them problem solved. I've also heard of the bottom bolt on the swivel hub coming loose & causing a knock.

Possibly just a loose top mount then.
Hopefully.

I had a knocking to the o/s/f when reversing and going over speed bumps. Turned out my one of the 2 links was seized at the ball joints. So stopped it from moving. Once changed it was fine.. There is a link on here with all the drop link bars and cheaper alternatives. Easy to change...

 

An old thread, I know, but did anyone ever get to the bottom of this?
I have the same knock at slow speed over uneven surfaces, but only in a straight line...
Can make the sound happen to order by applying brakes while crawling forward or by hitting biting point in reverse. Stops doing it with 1/2 a turn of steering either way.
Already changed no end of suspension bushes, joints, links and shocks.

 

engine/gearbox mount. im clutching here mind

 

They’re on my list.
But I’m puzzled why it doesn’t do it as soon as I turn off centre. And the noise sounds like it’s only just beyond the bulkhead. Makes me think it’s a steering rack/column bush or coupling?...
