Hi all,

I am rather new to this forum so please bare with me!

I have had my S2000 AP1 2001 RHD for a couple months now.

But I have noticed as of late, when driving very intermittently the whole car shakes, the gear stick is shaking you can feel it in the seats. This could be at any speed it will just come on.

Happened twice in the time of me owning the car.

The previous owner put JR3 18x8 ET40 5x114.32 Hyper black wheels on, with a skunk2 power exhaust system. With some different coilovers.

What would be the best thing to check? As for example I was driving for about 30 minutes yesterday and it started to happen I pulled over gave it 5 minutes and it didn't happen again for the rest of the drive, or even on the way back which was another hour-ish drive.

Speaking with previous owner, they think it could be the exhaust as it is pretty loud and droney sometimes.

Would appreciate any kind of experience or advice cheers.

sticky brake caliper ?

 

Hi.

I will take a look thank you.

It is rather odd as it doesn't happen all the time, and doesn't make a difference de-accelerating or accelerating it seems at the very least.

I noticed you're Norfolk way, do you take your S2K to a specific garage for works? I live local to that area too.

Thanks

 

No do my own work on cars,i dont trust anyone with my S2000
check heat on discs,by a flick of spit,thats what i do to compare

 

Thanks for the message back, should i do that after driving it around for a little bit and just pull over and check if any are extremely hot?

I did read up that some people are saying shaking could be cv joint buckets could cause it, but my issue is intermittent and i’m not sure if Cv joint buckets is a constant thing or a intermittent issue.

I’ll do as you suggest and probably run the car round tomorrow if weather is okay, and see if one of calipers is extremely hot with your handy spitting technique.

Cheers

 

Yes give it some spit flick after a drive whith vibration,you may see the heat if its the issue from smoking discs anyway..

 

It's a tricky one to track down this.
If it's a sticky caliper, the car will stink of brake pads and you only have to touch the wheel (careful as it would be extremely hot) after a short drive. Or, if you are on a very, very slight slope, release the handbrake. If the car won't move, it's a sticky caliper.
Other stuff like CV buckets can be possible - usually when they fail, you can hear a big click from the rear in reverse. Swapping them round can fix vibration as the wear in the bucket "moves" to a new wear angle.
Also, have the rear hubs been torqued recently, beyond 250lbft? They are under torqued from the factory and may require a loosen, regrease face of hub nut then 36mm re tighten beyond it's last position, typically a quarter turn if you can.
You may also have worn/cracked diff bushings. Or worn rear bushings/toe arms.
Needs a good poke around in fairness as it can be a number of things... How many miles, what year is the car? Also, has it been lowered?
If lowered, inner axle spacers can cure a bad vibration. Mine is quite low and I fitted them. It also cured a reverse click, as did also the hub nut re-torque. Good luck

 

Hi all, i have just pulled out the documents and works it’s had done which was given to me.

It had BC Racing Coilovers installed.

2024 it’s had front discs and pads and rear discs and pads.

Mileage at that time was 102k and now it sits at about 104k previous owner barely used the car.

It has oil filter and air filter service every year.

Today i’m also going to check the tire pressure to make sure it’s all up and okay, just need to find out what the pressure is meant to be has he put yokohama 18inch tires on it.

Cheers

 

Thank you i’ll be taking a look more today.

Checking the brake callipers, they do have a little noise to them when i do break. And to be fair, i literally don’t have any other noises whilst driving or reversing.

Its literally just when i’ve been on motorway for a little while these two times the car just starts this vibration but the misses thinks it started on the passenger side footwell.

First and second time it happened i had to pull over as i literally thought the wheels were going to fall off or the car had a puncture of some sort.

Normal driving round my village, and across to other villages basic driving nothing special it’s completely fine no problems no shakes no noises.

So i do find it rather strange, if it was buckets or mounts i’d of expected it to be all the time regardless of driving slow/fast or period of time.

Cheers

 

Hi Mate did a quick run from peterborough down to huntingdon, 20-25 minutes.

Car started doing the shaking but partner could feel it started on left hand side. Noticed car was pulling to left a little.

I actually got an infrared temperature laser gun and pulled over.

This is from pointing at the calipers Left front side caliper up to 120c

Right front side up to 40c

Right rear side up to 40-50c

Left rear side up to 30-40c

What do you guys think?

Cheers
