Re: 3.2 V6 Blown Diffs

I rarely go to them anyway as they are to expensive, lucky for me, me and my dad have a pretty good relationship with an Alfa mechanic going back to our Fiat days so we go to him instead and his much more trust worthy.

As for the blown diffs there are heaps of good points on this thread and it looks as if they all contribute (VDC, stress concentration & lubrication). In my opinion the lubrication is a very interesting point. It seams as if significant lubrication has already been lost after normal driving and the pinion gear is receiving very little oil and in the hot climate and low rpm it is binding to the shaft or bearing causing it to seize and with the sudden shock loading of the engine it is shattering the gear and turning it into a bullet destroying the housing with it. It seams as if the diff is capable of the power but still Alfa’s fault either way because for whatever reason it is not lubricated right. Just my opinion but I will be making sure my oil is topped up and possibly installing a Q2.

mate have a look on ausalfa.com :: Index

PLENTY of guys to prove that the diffs were an issue in Aus especially.

If he has never heard of a diff blowing, then maybe WA has just been lucky?!

Re: 3.2 V6 Blown Diffs

The big killer is axle hop.
Being an ex-tech, I saw a few and it was mainly when you slam the accelerator, if one wheel spun, it would wear away at the planetary gear shaft and eventually you would get a fair bit of knocking on overrun. In that case, if you could catch it early enough, you could replace the planetary gears or fit a Q2 diff. But if you feel the wheel bouncing when you tramp it, back of quick because rapid successive action the tyre gripping and breaking traction would be like hitting the planetaries with a cold chisel. It's a drawback of high powered front wheel drive.
Come on Alfa, let's get back to rear wheel drive like a true sporting brand should.
