next step in removing the torque tube to get to the bellhousing is disconnecting the CV bolts at the rear axles. You’d think this would be easy, but triple square bolts are quite evil.
You only need to disconnect the 12 at the transmission side, and I succeeded in removing 11/12 and disconnecting the passenger axle. What you see here is the stubborn 12th: rounded out and stuck with the driver side. Gonna have to cut the head off this one.
In the meantime, let’s quickly look at the wastegate actuator I removed this morning.
Fun fact: the 930 and 931 share the same wastegate. This was the cause of my exhaust rattle, the bracket supporting it to the torque tube was at least. It’d failed and because the only thing left holding the wastegate was the J-Pipe connected to the exhaust header. Below you’ll see the original and broken zinc chromate coated next to my replacement.
At least until I get that last axle bolt out, I can unbolt the torque tube from the bellhousing and accessories from it as well. That’ll be “Step 3” later in the week.

The axles/bolts on transaxle alfas are very similar, I’ve stripped out plenty, luckily never bad enough to cut them off (and they’re mercifully for hex wrenches), but I have used 8 foot long pipe as leverage to get them to move before! I u sually put new bolts in, but with yours being such a weird head are new bolts readily available ?

I’ve only needed a ratchet and socket to remove these. A “ problem” with this design is that they’re exposed to grease and if not torqued properly are prone to backing out. That’s how the first bolt came out. Fortunately these are sold in spades still, they used this bolt from the 914 to the 968 and I think maybe the 986 Boxster as well. They’re less than a dollar a piece so until the day comes that I get annoyed enough to replace them with grade 12.9 hex Allen heads, I’ll use these and add loctite.

Wow, guess I shouldn’t be shocked that even when an Alfa part can be replaced with stock hardware, Porsche parts are more readily available than Alfa parts! Al fa parts sellers charge $4 for these bolts, but they really are just the correct size Allen/hex head bolt. A nywhere with a good metric selection will have the right size, but a good metric bolt selection is harder than it should be to find

I recommend checking out Bel-Metric for fasteners and hardware if ya don’t wanna pay dealer or parts supplier prices. They have literally everything and even more.
You can very easily get lost there.
