Hey Guest!
PeterK said:I changed them all out on my 4A. Had to grind off the peening on the backside of the rear hubs before I could unscrew the threaded studs. They were not pressed just in on the 4A rear. I replaced them with a Dorman 7/16" stud from a late 80s Chevy wich required that I drilled out the original threaded holes a bit. The new studs are pressed in.
The font studs are pressed in and pressed out.
