·As this subject comes up from
As this subject comes up from time to time, I thought I'd post some information I've gathered through the years....
Virtually all Ferrari from the 246 Dino through the BBs use the same CV joint and boots. There is no need to replace an axle assembly if you have a bad joint. Usually, due to the heat of the exhaust headers, the inner joints fail first. Typically symptoms can be vibration from the rear of the car, noises on acceleration, clanking type noises on turns...or the obvious CV joint grease all over the headers.
Once you've got the axle out, it doesn't take much time to clean, disassemble and inspect both joints. The joints are the same as early Porsche 930 (1976-1986?), BMW 6-series...LOBRO PN-C.153.15.87.002 or BMW PN-33 21 1 205 840. Sorry, but I can't remember what the CV boot (kit) crosses to. I don't believe its the same as the BMW...
There a "C" clip which holds the joint on the axle. Once the clip is removed, the joint can be pounded off...
Although the joints can be sourced from most Porsche suppliers, I purchased mine from Rutlands.
Joints are typically less than $150 each, boot kits around $30....and far less than the $1100 or so Ferrari gets for an axle assembly. As axle balance is not an issue, there's no good reason not to replace individual joints..

David
