I am afraid that something is wrong with the diff, but I am not sure.

When I come off the highway, it makes a grinding noise like the brakepads are worn. I know it is not the brakes (I checked the pads) because when I hit the brakes, the noise does not change.

I jacked the car up, drained the fluid, and it looks fine. the wheels spin opposite of each other with no noise. I took the wheels off, started the car and let the rear wheels spin in 6th gear. I can not hear the noise.

So, from what I know, it only does it after highway speeds, no fluid is leaking, and there is no jarring from a tooth bad or anything. It does not do it when cold.

The car has 60,000 miles on it and has one season of autox.

Any ideas?

Sorry can not help you here......

One question?? How do you like your adjustable sway bar from comptech...and is it worth the money........and any other suspension mods in the future???

Thanks and good luck

I like it so far. It is squeking right now. I have to put more teflon on the mounts. I have to stay stock righ now on the suspension because I run the stock class.

Anyone ever had this problem???

 

Okay, I am now thinking it might be in the axle shafts. I drove the car around aith the door open and it sounds like it is coming from the driver side rear wheel. I even let the car coast slowly and I ran beside it (unsafe I know, but I was in an open area.)

Has anyone had problems like this?

Thanks,
Chip

 

i helped another S2K owner diagnose a problem that sounded similar. its probably your CV joint. the caps on the cross (this lets the shaft rotate and go up and down with suspension travel) has small needle bearings in it, if these get smashed ir broken somehow (high rpm launches) it will make noise, but it would be more of a clunking and there would be play in the shaft. the S2000 uses a mechanical differential without any clutches, just alot of planetary gears (8 small ones i belive 3 larger ones) and given the size of the rearend in the S these are pretty small, and you may have broken one or even a tooth or two on them. i am just speculating but i figured id throw out some ideas on what it may be. goodluck finding/fixing it.
