Purchased a 2008 G37s about 3 weeks back. This weekend on a trip out of a town, my clutch pedal started sticking to the floor.. From there i could barely shift, and I had to basically limp the car home, after turning around.

After talking with the dealership, it seems my Slave cylinder is going, and the clutch needs replacing. A clutch, I can understand.. wear and tear.. but the slave going seems to be something that happens alot(after researching).

for those of you who, probably have had this issue.. what did you do? Are you keeping the car, did you get an extended warranty?

Also, what should i expect to pay for a clutch/cylinder replacement? Im willing to go to an independent as well.

 

Unfortunately my warranty was out when I have to get my slave cylinder replaced and it cost about $1000 installed by the dealership. For clutches go aftermarket. However with our cars when you get a new clutch you need a new flywheel as well. Do everything together. A good clutch and flywheel will cost about $1000.

 

^^ Thanks blue. Do you have a preferred website where I can source parts like the clutch and flywheel. Just spot to the dealership, who said they have no problem installing aftermarket parts.. they just wont warranty them.

 

There are tons of clutch kits and fly wheels around. My suggestion is do some Google and forum research to find the one for you. I went with an ACT clutch kit with a lightweight Aasco flywheel. You can start there. There are also tons of vendors on here that sell clutches etc and they will hook you up on a deal. As for the work I did my slave cylinder and clutch at different times. I had my clutch installed at a specialist shop. (labor cost less). When I got my hydraulics done I had it done at the dealership only because I got OEM parts. I am pretty sure there is an aftermarket slave kit for our cars though. You can get aftermarket parts installed at the dealership however it will cost more. I guess it just depends what you want to do. I know a plus to taking it to my dealership was a free loaner car and I made them do a 100 point inspection and oil change.

 

Everyone here will highly highly recommend the Heavy Duty CSC. I personally went with the southbend stage 1 clutch/flywheel kit. You can get everything from here: Infiniti G35/G37 Performance Powertrain Parts, Upgrades, and Accessories

They ship very fast, and i dont think i could find anywhere cheaper.

Also, many people may recomend doing to master cylinder as well. When i did my CSC and new clutch, i didnt do the MC, and everything was fine for awhile, but eventually i needed to do it, as the problem came back. So that might be something you should look into as well.

 

Mine just died recently too. I'm going to go with the South Bend Stage 1 with their billet flywheel, HD slave, and master. I highly recommend you get the HD slave from ZSpeed.

 

The other thing i didnt mention (and I'm sure if you've done any research at all, you have found out), with aftermarket clutch/ flywheel combos, typically the flywheel is MUCH lighter than the OEM flywheel. The reason this is noteworthy is because there is clutch chatter. I'm the type of person who HATES no having the car sounding good. And although i will admit when I first heard the chatter, i regretted getting the lighter flywheel, i currently dont mind it at all. Anyone who's in your car will usually ask... "whats that noise?". Your response... "thats the sounds of race car"

 

So i'm currently, still under powertrain warranty, will an aftermarket clutch/flywheel void that? Also, do you all suggest i stay with an OEM Master cylinder, or go aftermarket with with that as well

 

^Only if whatever problem you have is related to the part you changed. Then again in this case why not just have the dealer swap it under warranty and upgrade the slave when its time for a new clutch. If your doing the clutch for sure I'd recommend just getting both done now.

The master on these cars is pretty strong from the factory from what people say but if your changing the clutch and CSC you may as well change that (its not much more expensive)

 

Currently, there is no aftermarket master cyl, just the slave. You didn't specify the vehicle mileage, but being a 2008 we can assume it's up there. Get the master done at the same time, even if it is out of pocket. It will save you headaches down the line.

Also, to clarify, the slave is only covered under the basic warranty. Powertrain will not pay for the slave. If you have an extended warranty, that usually covers this (the from infiniti does).

 

Yeah, I tried to get dealer to replace the slave under warranty, no dice.
Any thoughts on the
South Bend Clutch silent disk
ZSpeed Performance Nissan and Infinti Specialist

or the South Bend Clutch Stage 1
South Bend clutch kit flywheel Stage 1 HD heavy duty nsk-100-hd-o

with the billet flywheel:
Southbend G37 Billet Steel Flywheel 07+ Sedan, 08+ Coupe - performance parts

I would like to mitigate the idle chatter noise, as much as possible, has anyone here used the silent disks before? or is the Stage 1, more renowned/recommended

 

Lastly, how much am I looking at approximately for labor on this install? Sorry for all of the questions, just new to all of this. Googling what I can!

 

Try to find a reputable shop. If you talk to dealership mechanics they are no better and sometimes worse.

 

My 2008 is the same, it only rolled over 40K miles but my flywheel is warped and my master cyclinder was just replaced. Once I save a bit more I'll be putting in an aftermarket clutch kit and the HD slave as well. Here is the setup I'm going with and was recommended for being close to stock by ZSpeed:

-South Bend Stage 1 HD Clutch
-DXD Black flywheel
-HD Slave kit
-Motul Gear 300 trans fluid (3 liters)

My local independent Infiniti/Nissan shop quoted me about $500-$600 if I remember correctly for the job. So all in all it will run about $2,000+ for a new master cylinder, the HD slave kit, clutch kit, and install. Makes me cry a little inside as I've owned 3 other manual cars before and not one had any clutch issues.

 

I think Takman is about right. I can't fully recall if it was $500 or $700 for labor, and that was just for the clutch/flywheel and slave. I went to a local shop that my friend swears by, and they did a good job. Replacing the MC might cost a little bit more because its in a way unrelated to the changing of the clutch and CSC (those are in the trans, where the master is in the hood).

I cant help you too much with the silent disk, as I dont have it. I think i got the flywheel I did because although you cant resurface it, it is basically just a swappable disk when it does go bad, and the replacement disk was WAY cheaper than a new flywheel. Just to be clear (after I've done ALOT of research on it). What creates the chatter is the light flywheel. OEM our car has a dual mass flywheel that is big and heavy and basically absorbs the sound. Since the aftermarkets are lighter, they dont absorb as much sound. I'd be very interested as to how that silent disk clutch works out, but when i was researching, i dont recall seeing anythign about it.
