Recently I rebuilt a milano tranaxle and did some extensive gear lightening along with swapping in two extra plates in the lsd. Life was good for about 3 or 4 weeks then the diff started making awful bangs going around tight corners. One of the spider gears had broke into 8 pieces and its shaft had cracked in half! This car has a very light rear flywheel and solid clutch so shock loads are higher than normal, but since I dont do hard starts Im wondering if this might be a weak area. Has anyone else EVER heard of this before? Ill upload some pics when I figure out where the camera cord is.

Here is a picture of the destroyed spider gear and shaft. First time Ive ever seen this in an alfa. Looks like someone was doing drag starts or donuts or something. You cant really see it in the picture but the solid gear has two hairline cracks through it. So do the other two gears not shown. Im wondering , did the gear fail and crack the shaft or did the shaft break and cause the gears to go south.

This use to happen to 2 litre standard alfetta diffs without lsd, when you start to put a lot of torque through the diff dont be surprised if you start
breaking crwon wheel and pinions

Did the Alfettas have four gears like the milano diff?

nope all alfetta non lsd diffs have 2 spider gears

haahh dude,
that is the shit stain of the gear box. at least you can still make out the parts of your spider gears.

tomp: Can you post close up pics of the actual fracture surfaces of both the pin and the gears?

I find it hard to believe that the gear "leftovers" split the pin like that actually, most likely the pin broke due to fatigue and that cracked the pinion gear. What did the side gears look like?
