    I just broke a drive shaft of my 456 GT -94 so need a replacement.

    At eurospares they seem very pricey to me, almost 500 GBP.
    Would anybody know what other cars possibly use the same part??

    Or is there a way of changing the axle only as CV's seem to be fine?

    Any info appreciated!

    Thanks for your reply,

    Just got the part number, it is
    # 165072
    which is a successor of a part
    # 143103
    so either one would do.

    Checked it with the dealer as well, their price is quite excatly the same as Eurospares.
    According to Eurospares pages it is the same part as 456 M GT and 550 Maranello, so if someone has one lying around with CV's gone but the shaft still OK....

    ööh, yes and no, I was surely accelerating hard but wasn't doing anything extreme.

    very interesting problem. Don't understand how one would damage that part without other damage, which makes me believe something else may have gone bad during that stress too.

    However, there are other dealers in Ferrari parts but with this true problem: just the 165072 drive shaft is a very difficult part for a parts company to recoup on if one doesn't buy the entire train etc. parting out sub parts in the shaft area is not a money maker. They would have itty bitty parts left over and with no market.

    You might be forced to buy that part and feel unless you find a TOTALLY destroyed 456 [they come along sometimes, seen them at Ferrari salvage in Sacramento, CA]
    you will be waiting until the snow melts in Greenland....say about two - three years [sorry, had to joke a bit]

    Feel for your problem, not having been there in a Ferrari, but will try to keep my eyes and ears open in this area as Bay Area has one of the highest concentrations in the world if certainly not in North America.

    Might also try RiffleDriver on this site as he is very experienced in these vehicles and 'might' come across one for you, but he is VERY practical, and would probably tell you that time is money, and waiting for a drive shaft to 'fall out of the sky' is like waiting for Greenland...again. to melt. [BTW, email/PM me for his NEW contact address, as he does not frequent this site as much]

    keep trying here. though. rik

    Maybe a '93-'94 348, or a '95 355. I had a look at the parts catalog of you car and your have shaft look very similar to those on the late model 348 & 355's. The boot on the wheel axle side is sealed. The only question being if the lengths are the same, and they just may be???? But you'll have to find out for sure.

    Try giving Michael a call at Ferrari service. Here is the website http://www.ferrariservice.com/ He may have a used one lying around.

    Thanks Very much for you both!

    I have now a couple of requests going and waiting anxiously for the replies.

    The 348 & 355 seem to have different part numbers, but does that mean that they are different parts??? how does Ferrari do this?

    Yeah but you would be amazed the amount of stuff that can be swapped between cars. For example some 348's were running F40 half shafts (the Michelotto prepped LM cars if I remember correctly). Also, the later 348's (the spiders in particular) are running the same style half shaft & sealed outer CV joint as the 355's. So that is why I suggested the 348/355 half shafts. Like I said, I do not know for sure if they will fit, but it's worth looking into. If you find some off of a later 348 you really must make sure that they are the correct half shafts. The 348's ran two different half shafts. The early cars used the half shafts that had the same CV joint on both ends, pre '93 if I'm not mistaken, and as i already stated the later model cars ('94) had one side CV joint that was sealed (the end closest to the wheel). So make sure you get the one that has the sealed end.

    One thing that I think would make it a whole lot easier for you is if you have the half shaft completely out of the car. This what you can take it with you and match it up to the other half shafts. I wouldn't be surprised if they were the same thing. If that doesn't work try pairing them up with parts off of a Porsche. Ooooooh, I said a bad word.....Porsche....Hahahahaa:D. The 355's and the Porsche 993's are running the same style Brembo front break calipers. You may get lucky and find the half shaft matches a P-car???? Maybe a 928???? Especially since you are in the land of the Autobahn. So get the half shaft all the way out, so that you can take it with you and compare it with the others.

    Good luck, and let us know how it turns out.

    actually, not a bad suggestion. Porsche does have many similar parts.

    You never know.

    One of the guys found that the O2 sensor for our 348's is the same as the O2 sensor on a Volvo 850. It's nothing more that a Bosch unit. The CV joints are made by Lobro, which if I'm not mistaken is a German company, and they make LOADS of CV joints. I bet if he looks hard enough he can find a new one at a NON-Ferrari price. ;)

    wow, now if only I could get the prices down on my Volvo...they seem to charge an arm and leg too for almost anything: what's next, MG for Volvo swaps....

    good news on that O2 though....perhaps should start some cross thread or relation db on such.

    I am getting this issue sorted. Going tomorrow to Belgium to pick up a second hand drive shaft from a member of this forum, Kinnie who gave me a good deal on a complete part.

    Thank you all very much for your help!!

    Best regards,

    Erkki

    PS: sure hope that the issue is sorted with the new part and there is not something else broken as well...

    Sorted.

    Man, those screwes holding the shaft at the gearbox were tight! a couple of them went round when working on them. I couldn't find similar ones anywhere so have that now back together with the old screws but have ordered new ones from the local Ferrari dealer.

    They requested me to fax a verification of the order... for 6 screws costing about 1,50€ each! and the lead time is about 2 weeks.....

    Thanks for the update.

    Yeah the allen bolts sure are on tight aren't they. I had to use a big breaker bar with a cheater bar on the end of it to get mine to come lose.

    Finally got the new screws from Ferrari.

    Would anybody know how tight shall I tighten them?




    BTW: when getting the old screws out I had the bonus problem of keeping the parts steady when loosening the screws. That was because the axle was broken we weren't able hold everything still from the disc either... until one of us thought of putting the gear in and hand brake on.... DOH, so easy it can sometimes be.
    Hopefully this helps someone someday.

    don't know on the torque, but you surely used some sort of loosening oil on the bolts?
