:-) I'm following this thread because I've always had the 'knock' on the o/s front.  I largely ignore it now but I'd still love to get rid of it

Rich I'm replying so you know we care :-).  That said, I've no idea what could be making those marks.  I can't think of anything that is in close enough proximity - especially that one on the lower part of the damper. 

Anyone else?

Just my initial thoughts...

I'm 59, have an IS200 and looking at the video I don't really see much of an issue.  There are no other cars in sight and the speeds are relatively low.  If it had gone awry, it would have been a low speed knock into the kerb. 

I have, in my younger days, thrown the rear out at roundabouts when conditions permit.  I once had a Carlton GSI 3000 24V and that chucked it's rear end out with the barest whisper of too much throttle.  With this in mind, it was a good idea to get to know what to do when that happened :-)

Personally, I think the stock speakers sound really good - and that's coming from a hi fi buff.  I've had my IS200 for 11 years now and still enjoy the stock audio setup.

Does anyone know where I can get one (see attached file (platinum colour)).  Apart from the dealers that is.

Cheers all,

Paul

That sounds like the drop link.  They are not expensive to replace, I had both of mine done.  The 'knock' is still there though. 😕

You will - I've enjoyed mine for eleven years, even with the knock.

Mine's been in today for this. Pads moving they reckon and seem to have stopped it.

Give it a day or two - my knock goes away when it's been up in the air with the suspension relaxed, then it comes back.

Mine's all the time when I go over bumps.  Like a 'clunk'

I'm going to revive this thread.  I've had my IS200 for 10 years, with the knocking all that time on the front o/s.  I've had shocks, upper shock mount, lower ball joint and drop links changed.  I've also fitted new guide pins to the calipers and put new discs and pads on. The car has been inspected by a number of people who cannot find anything wrong.

Still the same knocking noise.  It goes away for a day or so if I raise the front of the car and let all the suspension relax, then it comes back.

Any further ideas people?

The tiniest of rust bumps can cause excessive run out.

I had my wheels refurbished by Lepsons this year (fantastic OEM finish). As part of the process they test for out of true.  One wheel was , so they straightened it.  The only time I had a wobble though was when I put new (Lexus oem) discs on the front. The hub surfaces weren't flat, causing excessive run out.  I spent some time flattening the surfaces by sanding and scraping. Job done - no more wobble.

It may be the wheels, or perhaps warped tyres- try swapping the wheels front to rear  but suspension  issues can also be to blame.  Lower control arm bushes are a common culprit - have a look at them to see if they are degraded.

Spot the difference 

Thanks to J Henderson for the tip.

I've got an extra button on mine - Snow.  It reduces the throttle response and in the snow it.... doesn't help at all🤤

In it's life mine has had one offside front lower ball joint and all round damper renewal, and that's it suspension wise.  I recently spent a satisfying day replacing the radiotor and while I was there I also did the water pump, which didn't really need it.  

That is is all I've ever replaced in the car 

They are such robust cars. Mines now on 145k and has never failed an MOT.

My seal is not breaking up but it is starting to distort a bit so id be interested to hear the response to this

I had my lower control arms  off a few months ago. After 145k they are fine.  It seems rather variable when they deteriorate.

Hi next time try the denso hybrid ones, they are excellent and look great too

Would you have a link to these?

Had the same trouble bought the ones from Lexus no more noise 

If these Michelins are still noisy I'll go to the dealers.  They're not far from me in Woodford - I see you're in Essex like me.

Fitted new wipers to my IS200.  These are Michelin ones, I'm hoping they will be quieter than the last Bosch set.  I've always had trouble with the drivers side being noisy, and never quite got to the bottom of it.

Runout 10 mm from the outer edge of the disc should be no more than 0.035 (IIRC).  The smallest amout of rust on the hub surface can throw this outside of tolerance.  Ask me how I know...

I didn't have any problems getting the magnetic base held steady, I think I attached it to the arm that goes to the upper wishbone.  It was a couple of years ago though so I'm not sure about that.

I have a small weep at the top left of my rad (128k miles), so looking for a replacement. 

Anyone used these:

Codes and codes again.  Get them read.  It will almost certainly point you in the right direction, otherwise it's a bit of a guessing game, with possible needless expense.
