Which CV has tendency to come loose?

Which CV joint has the tendency to come loose? Inner (transmission) side, outer (wheel) side, or both?

Thinking about running Stage8 CV bolts but wasn't sure if i should do all 4 CV joints or just the side that more commonly comes loose.

Thanks in advance.

Both sides can come loose but I've seen it happen a lot more on the inners. We used the Stage8 bolts on the inners only and they worked as advertised.

Thanks for the feedback Cory.

What do you do to the outers? Blue loctite, Schnorr washers, 12.9 grade m8 x 50 mm length bolts from mcmaster carr?

On the outers we just used the factory hardware from Porsche, torqued to spec. I only remember the outers coming loose once or twice over the years. The inners loosened up several times, even with schnorr washers and new hardware, until we switched to stage8. This is mostly track experience, and one of the cars had the engine and trans lowered and I think that extra angle contributed to them loosening up. There's a lot of threads about cv bolts on Pelican full of different experiences and solutions, some people get pretty fired up about it.. If you aren't experiencing any issues with them coming loose you could just try the factory bolts and Schnorr washers first. That works well for most.

I've never had one come loose myself in 100K miles of street and approx. 50 track days of use. I have had the CV's off for various engine maintenance several times and once to replace boots. Just re-installed with same hardware and torqued to spec.. No locktite or schnorr and only the stock half moon washers with two holes. Have never understood all the issues others experience.

one that is not put on properly

the bolt lengths need to be correct. there should be 2-3 threads sticking out past the flange.
ideally new washers
clean. try to keep grease off the threads
torqued.
you can get bolt lengths in 5mm along with washers at Fastenal. they come in a bag of 50.
still cheaper than buying the correct number here on pelican.

check the bolts after 2-300 miles

I prefer nordlock washers to schnoor washers. Available at McMaster Carr under "wedge lock washers."

The Stage 8 fasteners look great, but seem like overkill to me.

The 100mm CVs with M8 bolts probably come loose a lot more than the '85.5+ 108mm CVs with M10 bolts.
