The kit consists of;

12 torque to yield perimeter half shaft bolts
4 torque to yield cup retaining bolts
2 thick case hardened washers with a counter bore in them; the earlier versions did "not" have the counter bore in the washers.

Lastly; the perimeter bolts go through reusable plates that are there to allow for proper torque and clamping force distribution without CV shell distortion.

The final version is 4G7Z-4B490-A

However I only install the AccuFab/ARP ............... they are not torque to yield bolts as such will allow for future service without replacement needed.

Takes care

Just Got My Recall Letter...Oh, I mean CSP!

Just got my Customer Satisfaction Program letter for the shaft bolt and washer issue!

Thank you to DBK for compling the list and giving it to Ford to see that we indeed had a problem:cheers And thank you to Ford for stepping up and taking care of this:thumbsup

Now, my only problem is finding a Dealer qualified to do the work:frown

Today, they extracted 3 bolts on one side, 1 bolt on the other side, and are using the 4G7Z-4B490-A for both axles and removing and replacing all bolts and all washers
Randy, sorry to read about your misfortune. Don't worry as I am sure all will be better soon. Your tech may be very competent. Having done dozens of axle bolt upgrades, I offer the following:

1. As there are only two axle bolts per side, I assume it was a typo above to indicate that 3 bolts were extracted on one side. :eek
2. Tech should re-tap holes and with the tap, thread depth should be checked. We've seen cars with nice threads but where there was significant loc-tite build up at the end of the hole. If not checked and corrected, the new bolts can give a false torque reading where they are actually bottoming instead of tightening against the new washer. Only 1 car in 10 will have this build-up, but 10 cars in 10 should be checked for it prior to assembly.
3. As a precaution and as long as you're "in there", I would highly recommend following TSB 05-10-13. In short, I would advise that immediately before installing the washer, clean the surface immediately behind the washer which is the end of the splined output shaft. (Transaxle fluid will have a tendency to seep down the splines and into the coupling.) With this surface cleaned, you can smear some black RTV around the perimeter of splined axle surface before installing the washer and new axle bolts.
4. It is very important to follow proper torque procedures. There are too many mechanics who have convinced themselves that they have a torque wrench build into their elbow. Don't let this happen.
5. The outer bolts around the coupler also have a specific 2-step torque procedure. This can be done more efficiently if the tire is slightly lifted from the ground so that the axle can be rotated into positions where the to-be-torqued bolt can be accessed with the torque wrench. If the bolts are not numbered prior to doing this process, you are virtually assured of straying from the procedure.

Service In Orange County, CA?

Does anyone know of a dealer they would recommend in the Orange County, CA area to do the bolt repair?

I've had John at Ken Grody do an oil change. Nice guy. The dealership experience is simply standard run of the mill, as far as I experienced, but I would trust John to work on my GT. I will probably have mine done there after I get the letter.

For those of us in south Alabama and Mississippi and northwest Florida, Treadwell Ford in Mobile has excellent references with GTs, they currently take car of 7 GTs.

They are getting mine for the bolts replacement and regular maintenence Saturday.

Ask for Shay.

I am so depressed, we will have nothing to bitch about...
I think we should shut down this forum.
Should we start a poll...


Or we could have rally XXXV at Frankie's house???
Sorry Bony - I do not mean to do this to you...

BUT... I Can't Help Myself...:wink

We can still bitch about the White/Orange car:biggrin

I thought it was a package of 12 bolts, or 6 bolts per side.

Info was from Service Advisor, I will verify with tech. Thanks.

UPDATE: Tech says it was 2 bolts on each side sheared, he removed one, and specialist removed the 3 others.

'Best argument in support of Accufab's bolts there is. Well, that and the fact that there's NEVER been a reported Accufab bolt failure. EVER.

'Sorry to hear about your pblm, Randy. 'Gotta be a total pain...


(As an aside, Wifey & I just returned from 'Vegas, so, I thought I'd go to The 'Forum to "catch up"...and krymuny! I see we're discussing those darn 'BOLTS again!!!:lol I thought for a moment I'd entered a dang time warp or something!)

refund or kits?

How many of us that have installed the accufab bolts will be going for the refund from Ford or just picking up the kit? Not so sure what to do.:confused

Update: I wanted to let everyone know that I have my Ford GT back in my possession, with the proper and current parts package used 4G7Z-4B490A installed, properly torqued with tools (not elbow) and road tested.

Ford and the Dealership have stepped up to the plate, and after much research and discussions, I am in a good place, and back to fully enjoying my cherished GT again.

Why don'tcha just wait until Bill & Jay & the other "tech" types here on the 'Forum have had a chance to look at these new bolts, compair 'em to the Accufabs, and render their opinions on which way to go? :shrug

(My own guess is there won't be enough difference to warrant replacing the 'fabs, if they're already installed.)

Gents,
I think if you read CAREFULLY the posts of INDY GT you will conclude that the Ford bolts now being used are equal to ACCUFAB's. Just from another supplier who sources Ford's rod bolts... If you have Accufab's bolts in your covered.
