Limited Slip Differential Bolts for Si (if you don't like real tech threads don't click)
The installation of my 5.06 FD, clutch and flywheel was just completed a couple of days ago. While it wasn't without a few bumps I have to say It's a night and day performance difference. But this thread isn't about that.
This thread is an alert or warning to any Si owner who may drive their car aggressively. I don't beat on my car but I drive it aggressively and without incriminating myself there have been some off highway moments.
There are 10 bolts that attatch the LSD to the Final drive ring gear (see illustration 2, 4).

During the installation process the tech discovered that binding had been going on and compressed the threads on the bolts or stripping them I suppose you could say. Over time they may fail completely and things can, well, draw your own conclusions.

I suggest if you are installing a 5.06 FD or getting the 3rd gear set replaced per the TSB that you have these bolts replaced. If you have the cash and ARP has replacement hardware for this, get them. I would have but I didn't have time so I had to go with OEM. FYi I have 18.3k miles.

that is a little scary.
I bet that final drive feels good. do you track your car or just enjoy spirited driving? either way it's very benificial.

I'm not sure if I can tell by the pictures but were the bolts stripping at the bottom of the thread, or near the top of the thread.

see the parts that are really shiney and almost none threaded

I don't see how binding would cause the bolts to strip. I think it's a product of bad assembly. The ring gear and the diff have an interference fit and either at the factory or someone installing a ring gear improperly used the bolts to fit the ring gear to the diff. that's my opinion
Kidnkorner,
I just got my car back from Honda for the 3rd gear repair. The dealer refused to install an aftermarket performance clutch at the same time so I am taking the car to my mechanics at Dynospot Racing to install the performance clutch and flywheel.
I assume they pull the transmission when they install the clutch. Any chance you could tell me what you think the added labor time would be to replace these bolts? If it can be easily done, I will have them do it at the same time. Do you have to tear the Transmission apart to replacement them?
Actually, they might has already replaced them at the dealer. I am looking at the work order from the 3rd gear repair. They show a huge list of bolts and hardware they replaced when they repaired 3rd gear. Do you know actual Honda OEM part number for the bolts?
Thanks

the transmission case will have to be opened to change those bolts out. your shop may charge for the added labor.
and yes the transmission is pulled to replace the clutch

Bro, if you are paying them to install the parts how can they say no? They might have thought you were wanting it done for free. It's an hour job if the transmission is already out of the car. My dealer charged me 3 hours labor which included the clutch and the changing the final drive. It would have only been 2 hours but the tech hit a snag with the diff bolts.

Thanks Kidnkorner.
The dealer said they would not replace the clutch because the 3rd gear repair was being done under warranty. I even offered to pay for the additional labor to do the install, but the advisor kept saying they "can't" install an after market clutch.
Anyway, an extra hour of labor cost is worth the piece if mind. I will just have my mechanics at Dynospot do it. To be honest, I trust the mechanics at Dynospot a heck of a lot more then I trust the mechanics at the Honda Dealer.
Thanks for the info.

Be sure to slam them on the survey and mention they refused to do extra labor you were willing to do.
I don't know what clutch and flywheel you have but you should be prepared for any problem like I had.

I believe my mechanic is recommending the following:
ACT Prolite Flywheel
Clutchmaster FX200 Carbon Disc Clutch
I will make him aware of the pedal issue and the Differential Bolts.
Thanks again for the Heads-up.

Honestly. Had the dealership put in the clutch, then that would have voided any post ,clutch install, warranty left on the trans. I know Ive personally told customers I wouldn't install aftermarket stuff before.
But also the bolts were not replaced with the 3rd gear set.

I am running this flywheel. The throttle response is greatly improved and anyone who thinks they still have rev hang will surely eliminate it with this part.

Wow, great way to spread erroneous information. Your chances of a dealer honoring any warranty claim may have been reduced but per the magnusson moss warranty act, unless the part or parts caused or contributed to the cause for which the warranty claim was sought the dealer is obligated to perform the service by law. Even if the part did cuase the problem the dealer can only deny the claim, they can't void a new car warranty.
The presence of after market parts alone is not grounds to deny a warranty claim. For example the consumer rolls in saying that his 2nd gear is popping out at will, after the tech removes the transmission he discovers the aftermarket clutch. The dealer can't automatically say well you have an after market clutch your warranty is void or your claim is denied. The dealer would have to prove that the clutch is the cause.
I installed an aftermarket clutch and the JDM FD and the dealer didn't say squat. With the issue about my clutch geometry problem they did say that if my throwout bearing, clutch master or slave cylinder went out I'd be SOL.

And any dealer will do whatever they want at their own discretion. Each dealership handles there warranty claims there own way in the confines that they feel acceptable. So if your dealership says that they will install the clutch and continue warranting your trans parts so be it. They just wont report that to Honda. Ive had warr adjusters come and look at cars I said needed a transmission. He denied the claim because of an intake. I don't think I was spreading erroneous info, maybe I didn't bust out the legal books like you did, but from my personal experience being on the other side of the dealership counter from yall says that no dealership is required to do aftermarket work to a car, then be held responsible when the it gets grenaded, and Id thank you to not be such a dick about it in the future. If anything I worded myself in my previous post incorrectly.
I work at a dealer in ohio currenty have a 06 apart on my rack. We put 3rd gear syncro in this car a few days ago. In addition to 3rd we are now ripping the trans back apart and found that both mainshaft bearings are worn and both diff bearings are worn. Our master tech blames gm engineering and the 3rd gear fix has no visual difference we all guess it is to get you by untill your warranty is up. I also know that our dealer is privately owned and we can't fix any part of a warranty that was done by another dealer. damn honda

So long as it conforms to federal law. A dealer can no void a warranty it did not issue. A New car warranty is a contract between the buyer and Honda, not a dealer.
Not every dealer or warranty/insurance/claims adjuster operates within the law. If an adjuster came in to look at the transmission and denied the claim simply because the intake was there is a direct violation of federal. If the consumer was aware of their rights and wanted to challenge that to the fullest, the decision would be reversed.
