Jay, I have been using a digital camera but who would have thought that all the lock nuts were different. The owner before me really messed things up. | ||

Re-use the original fasteners (unless they are damaged, then replace with new of same) --- the cone-shaped ones that were installed. The cones are needed for clearance. Clean everything well (use gasoline, brake cleaner, etc.). A little Loc-Tite on the threads will be sufficient. | ||

Tommy, do yourself a favour and buy a cheap digital camera and take lots of pictures before removal. I'm doing this on my restoration and it has been a life saver! The spare parts manual is inadequet in many cases but You can always refer back to the pictures that you've taken. | ||

For this application which fastenerer would be the right one to use ?? Nylock or the conned shaped ? As I was removing the shafts all the fasteners were mix n much !! | ||

Absolutely: LOCKING FASTENERS on rotating machinery --- always, no exceptions...Only a fool would not use them. In aircraft and spacecraft we go so far as to pin all the joints for shear strength as well -- not necessary on your axles, though... | ||

Get all new bolts,disassemble clean evrything spotless, regrease,imperative to use spacer washer washers on left side,then an excellent nut is a steel (SELF-LOCKING AT END THREADS)nut not nyloc aircraft get them at a industrial fastener shop in evry state they go up to 12.9 in strength... | ||

Ferrari and Porsche axle shaft bolts are completely different and fasten in different ways. Ferrari axle shaft bolts (CV Bolts) are 10 MM vs 8 MM for Porsche. Ferrari uses a special type lock nut and a raised lip that captures the nut, preventing turning. When properly torqued, Ferrari axles Bolts are tighter than the gates of hell and will not simply loosen on their own like the inadequate porsche fastners used on the 944T's. | ||

No, but the 308 does make enough vibration to loosen the axle bolts. I also recommend one drop of blue loctite on each bolt. It's always a good idea to clean threaded fastners, BTW. To answer an earlier question: no, the flanges are not threaded. | ||

The 308 does no have enough power to damage any axle bolts. Go worry about something else. | ||

Lawrence, Were you using regular nuts or lock-nuts when the shaft came off? | ||

I've heard of some people deliberately reversing halfshafts to increase CV joint life. I know with Porsches it is recommended that the bolts be replaced when removed. The holes should be cleaned (I'm assuming the flange is threaded) and Loctite be put on the threads. This is what I did the last time. The first time I did it, I had a half shaft come completely apart on my 944T. And the worst thing about it, it happened on the drive home from Road Atlanta. The road was clear on I-81. So I floored it. As the car accelerated past 100, I heard this huge wham sound. I simultaneously depressed the clutch and let up on the gas, and looked in rearview expecting to see clouds of smoke thinking I blew the engine. There was nothing. Pulling onto the shoulder I noticed the engine idling normally and all gauges normal. I blipped throttle. Engine was OK. Got out of car and looked under it. Driver side halfshaft was laying on exhaust line completely detached from tranny flange. I learned my lesson about the bolts. Had this happened on the track, it would not have been pretty. It was not pretty anyway. | ||

The axles are the same on both ends. It makes no difference. | ||

Peter, Brent, thank you both for the help. What about the joint. How can I identify which side of the shaft is facing the transfer case? Both sides look the same. Peter on that picture the end that you are showing is attached to the hub or the case ? | ||

Tommy, I did my gearbox seals a couple of months ago. The reason you need the washers on the outer side of the in board CV joint is because they shorten the length of the bolt so the end of it doesn't hit the bolts on the gear box as the axle spins around. | ||

Tommy, maybe this picture can help you:  That was Ed Gault who came across the washers on his joints. I never had them on my joints, just those crescent-shaped ones that two bolts pass through at the same time... | ||

I removed the axle shafts on my 82 308 with out marking the joints (which side faces the hub or transfer case). Both sides look the same and painted the same color. Is there any way of identifying them and if not what kind of risk will I be taking if they go in the wrong way?? On a previous discussion someone had mentioned that the left inner shaft joint has washers between the nuts & housing. They had mentioned that it was very important to put back the washers. I have looked at the spare parts catalogue and it didn't show any washers in the assembly. When I removed them some bolts did have washers and some didn't on both sides. Any help will be greatly appreciated |
