I took one of my axles apart this afternoon, one of my CVjoints is sitting in my parts cleaner
. Fortunately it is the one I planned on replacing. It has some grooves in the outer race that the balls ride on. The other one looks much better. Seems I read somewhere that I'm supposed to replace both CVjoints on the axle at the same time. My gaskets were not part of the boots, they stayed attached to the CV when I took them apart. The triangle you were asking about is stamped on the side on my CVjoint along with the month & year it was made (2/80). I did not have the long curved spacers. Can anyone tell me why I need new allen head bolts?
