97 Ferrari 456 GTA bought in auction

I had this on my Monaro, the door lock motor itself was on the way out. The car would let you know there was a locking issue by 5 short rapid beeps of the horn. I could lock it manually with the key or pushing the button down as you have described but it wouldn't have enough juice to do it electronically. A common issue on those cars as I found out, something to do with the solenoid in the mechanism. Bought a new unit and swapped it out, lots of swearing on the first one trying to get my oversized hands into the door. Second time around was much easier knowing what to do!

Completely different car of course but seems a very similar scenario.

Thank you and this makes sense - could be a good minor project for me over Christmas

lets hope Ferrari used a mainstream part

Fingers crossed!

So far the sensors appear to be Bosch as are the fuel pumps (changed last year) and I think the locking actuators. Suspension is Bilstein, so lots of German bits, which funnily enough are the parts that fail.

I concur - had mine for 7 years and the German bits failed including the alternator. I’ve never bought a German car (although I speak German and lived there for a while) and I was surprised to find so many German bits on a Ferrari. I guess they were desperately trying to improve the reliability of all the F cars at that time and fell for the PR from the German suppliers.

If I remember correctly the dodgy seat potentiometers were the same part as Jaguar XK8, so there are all sort of possibilities regarding the door locks. Great car though and well worth the pain for the looks alone.

My worst cars for reliability have all been German - Audi, Mercedes etc.
Volvos a close second.

Most reliable - Saabs, closely followed by (are you sitting down?) my 1990's TVR.

When I had an Audi A8, a Mercedes ML and the TVR back at Christmas 2014, the only one working for three weeks in the snow was the TVR.
They are actually quite simple cars, just need to be driven regularly.
Much of the TVR bad reputation comes from two things:
1. Top Gear
2. Being left in the garage for months.

Is the latter true of Ferraris too? Do regular good trips round the countryside benefit them?

[fastgerman]

Yes I can’t imagine any car being left to sit is a good thing, certainly not for the 90’s cars I’ve owned (Corrado VR6, 968 and the 456). In laws have a 1981 911 sc and that seems to be happy being left for 6 months at a time.

Potentiometer are probably from seats not quite so gigantic. I guess that’s the issue, the German parts are fine for the cars they are designed. Think I heard there is a Volvo wiper motor that controls the under bumper, rear spoiler. I need to go on an electrical course haha.

[Hurricane52]

I loved that rear spoiler - i think they binned it for the M models. Looked great and seemed to work.

Interim maintenance unfortunately needed this year…

I have a squealing (I think) wheel bearing.

Now, is this really the price of a wheel bearing??



Any help appreciated :-)

Give SBR a call. They will know if there is a cheaper option.

[fastgerman]

Have tried a few suppliers, thanks for the recommendations.

I have at least established that there is a normal looking wheel bearing within the hub but no idea what the part number is - Ferrari Parts Maranello don’t either.

The complete part above is more like £1k so hoping I can find the individual bearing assuming the old one can be removed and a new one pressed in.

[ferrisbueller]

Are there any numbers or identifiers on the part itself?

[Medic-one]

Stunning car!

Prince Bernhard, the husband of our former Queen Juliana of the Netherlands was also a big fan of these and ordered 2 of them in a one-off green colour that wasn't available for the rest of Holland.

I collected scale models as a kid and remember having the 1:18 model of this, which had the plates of the Dutch royal household on it.

He also ordered a 500 Superfast and 400i in the same colour.

I can only see 157900 for the complete hub. Can see some numbers here on the bearing but Ferrari don’t sell it separately

He certainly liked his green :-)

Presume SKF can't oblige with details, based on the image and some measurements?

I know there's some bearings you just can't buy without spending a bucket load more cash than seems strictly necessary to buy a whole new component....

[DanG355]

Scott AKA Ratarossa may be able to help as he is very knowledgeable on Ferraris and owns a 456 that he has done a lot of maintenance on. He is on YouTube and Insta but not sure how responsive or quick he is.

This. I would contact SKF directly.

[fastgerman]

Thanks guys, have emailed the SKF Uk team, will report back.

In the mean time I’m Googling away ‘ ferrari skf 157900’, which brings up some similar questions on the Ferrari Chat forums with no solution. The 348 has a bearing available but the 355, 456 and 550 seem to need the entire hub (what my current research tells me). Have asked Rardleys also who are investigating. Guess a lot of owners are happy to pay £1k + fitting for a wheel bearing…

You could ask or look on Ferrari Chat in the 456 forum:

https://www.ferrarichat.com/forum/threads/456-550-...

But the omens don't look very good I'm afraid. They seem to suggest that it is a special that uses the inner surface of the outer hub as the outer race of the bearing.
