Time to Replace the clutch?

kevin.z · 04-09-2010, 07:15 PM

first of all, rep+1 added for everyone!

i think the dealership is trying to rip me off. they said stock flywheel is $1800 and clutch is $1200.

I did noticed today clutch returned to normal feeling, maybe it is just overheat. Should i just leave it then or should i change the clutch fluid?

Am i changing just clutch fluid or both clutch fluid and brake fluid?

My clutch returned to normal but my car is screeching like crazy today. sound like i am driving with my handbrake pulled. could be my brake pad gone?

anyways, thank you guys for the feed back!

You can change just the clutch fluid, but you replace it with Dot 4 brake fluid (they are the same fluid types).

BTW you never need to replace the stock flywheel, it doesn't go bad. You can install an after market light weight flywheel as an option ($400 part), but you only at worst need a clutch ($400 part). Install is a good 4-5 hours of labor.

If you have squealing under braking then your brake pads/rotors may be a little glazed from some hard stops. You can do a light sanding of the brake rotors to remove the glazing. If it is squealing under normal driving then the serpentine belt may be slipping a little and need an adjustment, or check pulley for errant fluids.

well the stock fly wheel may need resurfacing if you got it really hot and warped the plate. and its a pain to resurface two-piece flywheels so a lot of places would just replace the whole flywheel. surface grinders don't like parts that move, i've done it before but you would have to have lockout pins made to hold the top piece from turning, and it's a pain in general. chances are you're flywheel is fine though. if you drive the car on the street i would stay organic for the clutch material as it is the most forgiving. i would change the fluid first and see where that gets you. I had 10,000miles (16,000km) on my clutch when i put in my jwt clutch and flywheel and i still had plenty of material left on the stock clutch. I rarely see clutch replacement prices go over a thousand. but stealerships love to screw people on maintenance. just drive down to St Louis and have Lou hook you up.

How do you like your JWT clutch/flywheel? Better Performance wise?

driveability is fine, it does rev faster, and i wasn't slipping the clutch before so i can't really tell you if there was a huge performance difference until i have more power under the hood
