Cam Bearing or Gear Box Whir/Whine

Have you checked for antifreeze in the transmission?


When was the gear oil last changed?


What type of gear oil do you use?



BTW, posting recordings is pretty useless. The sound never comes out the same.

Not an engine problem..

 

Well if you think about it.. wouldn't an engine issue manifest all the time?

Sounds tranny-ish. By no leaks they assessed the coolant-transmission oil intercooler?
It sounds like going to have to go through it. Tranny fluid in a 360 is different than say a porsche. You have higher operating temperatures in the engine bay that will degrade the fluid faster than other cars. A yearly changeout isn't a bad idea. Might not be a bad place to start.. has transmission mount ever been changed?

 

I really don`t want to scary you, but if the noise so loud as you say, something inside the gearbox will be bad already and the oil change will not fix it, just my opinion ..

 

Way I see it.. once the tranny oil is out you can get an idea of the condition of it and metal shavings and content in it. If its a bearing in the transmission or another component that requires a rebuild then oil change is a comparatively cheap thing to work through anyway... I used Redline in mine last but I think Im going to do the Spirax route next...

 

Any update?
I would bet that is a worn differential, either the traction unit or main drive gear.

 

I would check:
1. Ebay
2. Ferrparts.com
3. Exotic Auto Recycling

You can find the last 2 online but give them a call, they will guarantee the parts will work when installed or you get your money back.

If you are interested in selling the damaged transaxle - shoot me a PM, I bet me & my mechanic could repair it, I want a spare for my 360 Challenge car, even if its not repairable I can use some of its parts.

 

Here is one for sale - I don't know the seller but may be worth some investigation.

Ferrari F 360 Modena Transmission 6 Speed Manual Gearbox 177892 183339 | eBay

Manual & F1 gearboxes are identical up to the actuating systems.

 

if it goes away, once the pedal is let go....it is not likely to be related to the driveline, right? A worn differential would make the noise under load and just rolling. It would not stop.

I have a whine in the cabin, as well. It sounds similar and it also stops when I release the pedal. It feels like an intake noise.

 

When they changes the oil did they remove and check the screen to see if any metallic particles were present? Just checking the oil would probably not reveal any as the screen effectively removes them. If it was never cleaned (probably applies to most cars) then you may find metal as I did but it was aluminum from the case machining process).

I disagree with your statement that a worn diff would make noise all the time. I just replaced one on my hauler truck. Most limited slip diff failures - and failure is a strong word, as they usually work but will not transmit torque to one side or the other- sound exactly like your video. You only hear noise while on the gas, total silence when coasting. If going uphill and holding speed- noise, flat out - usually can't hear it over the engine.

If you jack up one rear tire and leave the other on the ground, try to move the lifted wheel forward or back. Their should be some resistance. Different for every car but should require min of 5 - 20 pounds of force to get it to rotate. That is the clutch pak shifting the load. If it spins freely you diff is shot.

Can you still drive the car- yes, can you do damage to the transaxle- maybe, depends what failed. If only the clutch pack then you will be ok for a good number of miles. If a spring broke then something will eventually get chewed up. If your indie doesn't know all this, I would find a new shop.

I'm sure Ferrarri has a spec for the test above - on my GT3 - notorious for diff failures- it was either 8 or 10#'s.

Best of luck, sorry ur f car is making noises, but it's really not that bad.

 

See what I don't understand.. is if you're going to have to replace the gearbox anyway if there is a failure (and I agree.. I'd just swap it out with a used box versus open it and repair it) why not just drive it until it completely fails? Assuming of course that another part isn't killed by the bad box. Assuming its a bad bearing, will you get 10,000 miles on it?

 

Well, I may not own a Ferrari yet, but, I have experienced that exact noise in my old rx7. That video brought back the dreaded sensation I had as I was driving down the highway when I was 18 and my axle came out and wheel and axle passed me!

The next time I heard that noise was in my Camaro, I recognized it immediately and ripped the diff apart. There were broken teeth abound but it was still working. Rebuilt it and the noise all went away.

I would suggest having your mechanic take apart the diff and just have a good look around, probably the cheapest solution.

g'luck with everything

Have you checked the torque on external fasteners?

 

Not necessarily with Ferrari pricing!

I predict bearing on transmission shaft. Wouldn't you notice difference in while while on left versus right hand turns if in 5th gear if it was an axle shaft?
I imagine its a $30 bearing that costs $3000 in labor to replace.

 

My 430 developed a similar noise after the transmission was rebuilt. Wondering what veil May still lurk inside.
What did you find out about your car?
Thanks
Victor

 

Justin- The differential is part of the transaxle. The transmission and rear end are all in the same case and pump lubricated.

 

Did you ever find out what the noise was from. I have the same noise in my 2000 360 f1

 

Hello all, have a 2000 360 F1 with a whining noise under acceleration. Had the gearbox oil changed recently. Noise still present. Sounds like a bearing noise. Would assume Transmission or axle bearing starting to fail? Anyone experience the same problem.
