I've read how hard these are to remove and replace.

Has someone actully done that without the aid of a machine shop, or is the consensus that a machine shop is critical?
 
KVH-

Not positive, but I think the 4A may just have pressed in studs so it may not an issue for you. I haven't worked on them myself, but I have heard of several others who did not use a machine shop for working on the TR3 or TR4 rear hubs.

If your studs are the same as the TR4 and are peened on the back side, I'm not sure a machine shop will do anything different than what I did myself. I ground off the peened material so the stud could simply be unscrewed and a new one screwed back in. I of coarse did not peen the back side of the new stud, only used lock tite and have not had any issue. I did this 5 years ago and check the stud every spring to make sure it is still holding well.
 
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.
 
KVH -- I suppose the task becomes more difficult if you need to separate the hub to get at the backside.

I have a hub puller if you ever want to try your luck with it.

Peter,

Just to clarify, is your TR4A IRS or not? It's possible there could be a difference. Mine are both IRS but I never had to change a stud on them (I did shorten them on my original one to convert it from steel to wire wheels).
