Yes, the long 10mm hex head bolts. The factory ones are 10.9, but I actually found 12.9 ones at Fasten-all that are really nice. The only difference is they are threaded all the way instead of half-threaded like the factory ones. Hopefully they are just as strong since I used 6 of them on one side. Should be, but I am a factory part kinda guy.
It seems you always tear up a couple when you R&R an axle. Next time, I will remove them 100% by hand. The impact struggled on a few, and I guess those were the ones that the threads got worn down on. They screw in real nice when coated with oil like the manual says. I just used anti-seize last time, didn't notice the oil recommendation.
