I there any difference between disk brake wheel studs and drum brake wheel studs? I am about to buy longer ones for the rear and I found a set that are the length I need, the correct knurl, and thread size but they say fits most disk brake applications. I don't feel like there would be a difference as long as the knurl size is correct but just want to make sure.

Cruiser (and anyone else interested), I pinned down my backfire. MAT sensor (aka IAT/ACT) went out. It's currently unplugged, and I'm driving in open loop without backfiring.

Check the impedance on your gear. Probably everything is 8 ohms.

Repost:
So I'm upgrading my rear brakes to discs next week and I just want to make sure I've got all I need. So I have backing plates, calipers, I think there called axle studs ( connect the backing plate to the axle), and the prop valve from the donor, and new lug studs, fluids, and gaskets.
Also will I need to do any modification to the hard lines on my jeep to get them to fit in the prop valve or connect to the soft lines on the calipers or is it just screw in and go?
Thank you guys.

Whats a tried and true way to tell if my excessive camber on the passenger wheel is from bad ball joints or a bad hub? I would just replace both, but I dont have that kind of money at the moment for both.

Jack up the tire, pull ebrake and shake. The wheel. If its a bad hub, you'll have wiggle. Shake it vertically not horizontally because you may think you have play when it's just the slop from the power steering box.
