DC640

I just went out to the track last weekend... i have another one coming in 2 weeks.. maybe I should hold out until I get new bearings and hubs from the dealer.

More reading although the top link is the important parts.

I think this should answer most of the questions that have been asked.

Maybe try calling the phone contact phone # and name at the end of this letter if you still don't have any satisfaction. Maybe, I am hoping, they will look at your case with a little more consideration. It might also help if you fall within that VIN range which is now publicized in this letter.

Let us know the final outcome regarding your CL's, and Porsche's reasoning on your car in light of this recall.
Hope this info helps you,
Happy Holidays,

Thanks. Good read. The details indicate that the "updated maintenance" will just be more frequent re-torquing of the CL nut if driven under track conditions. Probably means CL nut torque needs to be checked prior to every event. Hmmm....I seem to recall checking wheel lug torque being on every standard DE event inspection form.

Visited the dealer today to find out why I have not received recall notification... My car was built during the stated build dates...

As it stands, cars that had their hubs replaced under the earlier campaign AB01, now have the upgraded hubs fitted and will NOT have their hubs replaced again. So basically, if they changed your hubs last year and you have been torquing to 600Nm, as far as they are concerned you are fine and start logging your track kilometers.

This campaign is to pick up all the guys who own cars in the specified build period and who didn't have their hubs replaced with the upspec part under AB01...

As for the log book requirements, I don't know when they are going to notify the rest of us but it is very real...

Based on "track kilometers" logged:

Every 7000km: Rear hubs, bearings and CL nuts (approx AUS$3500 parts plus labour)

Every 14000km additionally to above: Rear wheel carriers (bearing housings), front hubs and bearings (Approx AUS$6250 parts plus labour PLUS cost of rears above which need to be repeated!!! That is $10k parts plus labour)

Every 28000km additional to above: Front wheel carriers (bearing housings)- (Approx AUS$8000 for the 2 carriers plus labour PLUS the cost of the 14k km maintenance... That is AUS$18000 for parts plus labour)!!!

As somebody senior pointed out upon reading these requirements, this is Porsche's f%*k up and they should have the decency to either (i) cover these costs and greatly reduced prices (ii) offer a free conversion to 5 lug for those intent on tracking and a subsidised set of wheels (iii) Redesign the hub and bolt to work within the current wheels fitted and recall all cars for a new fitout that has realistic service life (30-50k km etc excluding bearings which are wear and tear items)...

EVERYBODY there felt that it was ridiculous that the cost of such a grave mistakeon their part should be passed onto the customer like this and that we should start thinking about writing letters to PAG, PCNA, PCA etc to voice our dissatisfaction with their handling of the whole situation. Until Porsche introduced "technology" into the wheel fitting system, the most the motorsport team would see with previous generations of GT cars was a noisy bearing which is a wear item.

Yes, but remember that Porsche Motorsports, as well as every serious race team has time/hour limits on certain parts replacement, as well as certain specific maintenance intervals, and certain time/hours/laps where parts are removed and inspected sometimes even with xray,magnaflux, etc.

Here is one of Porsche Motorsports tech bulletins, complete with recommendations, for their Race Cup car GT3's before Daytona. Note it has sections specific to CL, wheel hubs, uprights, etc etc. Most GT3's these days with CL's and even without, should have similar schedules for misc suspension parts.

^ right on. i always wonder why my running cost was much higher than most others running GT3 street cars. turns out not many ppl replace wheel bearing, hub, axle, wheel studs, wheels on a regular basis.

VIN number is squarely in the middle of the recall. Will try calling the porsche recall person, I have a feeling I will get shuffled back to the same Don Thomas who is very happy to send me the same letter denying any coverage and any help repairing the vehicle.

Note, I now have real solid estimates on repair costs, about $40K. Might come in less but I suspect when all is said and done it will be about that number of the car to be as good or better than before.

Also, Porsche is not telling me how they are going to deal with my car for the recall since it is a bit broken (hell if I am going to put new replacement parts on just so Porsche can replace them effectively). So the question boils done to what condition can the car be in prior to the recall. No answer on that.

Looking at the cost of these for the future, the hub in the US is $407 and the bearing $68.00. It could be worse.

DC640

is this a exact replacement of existing bearings and hubs or will it be newly designed parts? im thinking Porsche is covering their rears by replacing them so that at least they are saying we did something. if it is nature of center lock design that is flawed to begin with, Porsche made a huge mistake by putting these on GT/Turbo cars instead leaving them as 5 lugs. Yes I understand if you use them under heavy track conditions, one should replace them as normal wear and tear maintenance but tradionally 5 lug design in past Porsche didnt have these issues.

We won't always have the favourable dollar position to fall on with regards to pricing... And its not just the hub and bearing either... They require the CL bolts changed, a whole lot of bolts that hold the wheel carriers in place and the wheel carriers themselves every second hub change. Those front wheel carriers are $4000 each!!! Thats at least $2000 each from the US not to mention the huge freight cost to haul them half way around the world... We pay double the US price... So what? At the 28k km mark you'll pay US$9500, shipping of $1k or so and $5k labour... Doesn't make it sound like much more of a bargain to me....

The we ****ed up but you must pay policy does not sit well with me... Especially when all of a sudden the maintenance costs make servicing a Ferrari like servicing a Toyota Corolla by comparison!!! Not cool!

The hub slightly changed in mid 2010. When the original recall was done to change CL nuts, hubs were inspected but not changed on all cars. The purpose of this recall is to change the hubs on those that were not changed after the first recall. My car falls within the recall period. The first recall saw mine changed... They will not be changing them again, same will go with all those cars not affected by the first recall (like MY11 cars)...

As pointed out by someone at the dealership today, cup cars have CLs to allow for fast wheel changes in racing and timing out plus maintenance are a given. Your average customer does not need rapid wheel changes, nor was this system able to provide that so they should never had put racing systems (ie CLs) on street cars... A recipe for disaster when you decide to fix something that was never broken, get it wrong then don't want to admit error and pay to do good by customers! All this talk of cars now needing to be maintained like race cars because they are so fast is bull**** because 5 lug wheels have not been lost on GT cars in the past 10 years and they've been driven just as hard!!!

gstahl, if they changed your hubs originally under AB01, I doubt you'll have much leverage as you would have had the later hubs on your car... If the dealer didn't change the hubs back then, you may have leverage against them on the basis of failure to update your hubs to the revised units or a claim against the dealer for failure to detect signs of wear and perform the recall correctly... Just an opinion based on the info I received for myself today...

sfo

AB01 was only about the centre lock wheel bolt, not hubs ..

as least this what is says on http://www-odi.nhtsa.dot.gov/acms/cs...2V558-4048.pdf

911rox

Incorrect! AB01 was about replacing the CL bolts, correct! But dealers were required to inspect hubs, wheels and rotors for signs of wear and to replace accordingly...

My hubs were done... Other guys here had rotors, wheels hubs replaced also...

ps. That letter suggests we were advised about service intervals during the AB01 campaign. THat is rubbish! We were told how to grease bolts and how to torque them off the ground. To date I have not seen any documentation from Porsche on the new proposed service intervals except for on the campain handout I was given at the dealership today... Thats all just lies from Porsche to the authorities to justify it's position. Maybe some litigation would remind them of the facts and their shortcomings in handling the situation....

Ouch. Tracking a GT3 just got a whole lot more expensive. Rear carriers/hubs/bearings/nuts and front hubs/bearings/nuts every 8400 miles. What is that? $15,000? Maybe $20,000? Whewwwww
