Hey, so I'm doing the zj disc swap and I'm just about done. Anyways, what's the best way to get the new studs in? I stripped the one pretty bad and the other 4 aren't stripped, but I'm probably going to run a die over them to clean them up. I put six washers on the studs and then used a lug nut and my impact to pull them in. Apparently that's a bad decision. How should I do the other side and the one I have to replace?

 

they sell stud installers they have the taper for the lug nut so you do not bugger up the threads also you can use your stack of washers but use a nut instead of a lugnut that should work better an also be sure to use sum lube

 

Which lug studs are you using?

 

The zj rears. New.

 

I bought new studs when I did mine and ended up having to go to a machine shop and have them pressed in.

Had a hell of a time with them.

 

1) Make sure the knurl is not too big for the hole you are putting it in

2) Use a good quality nut...not a lug nut, I& use spacers...flat washers would be best so you don't risk cocking the stud sideways

3) Use a light coat of lube on the stud

4) Use an impact wrench so that once you get it moving (pulling the knurl into the hole), you don't have to stop. If you stop, it will take more force to get it moving again & may damage the threads

If you have access to a ball joint installer, you may be able to use it to press them in without having to remove the axle...depending on the style.

When I replaced all mine with slightly longer studs so I could use some 1/4" spacers for clearance, I used the 4 step method above....worked fine, and I only messed up 1 nut & 0 studs.

But man, that nut got really hot !!!

 

I used a large C clamp & a deep impact socket. Went in just fine.

 

All I've got is the Dewalt 20v impact. That is what I used on all of them but the one I stripped. I'll have to find a grade 8 nut with the right thread. Home Depot only had coarse thread. I wish I had the larger Dewalt impact to make this faster. The little guy is great for most things and pretty compact, but the larger one has like 4 or 5 times the torque rating in the technical specs...

 

Same here, have done it this way for years.
