Hi I was changing drivers side driveshaft when putting hub on and tightening bolt it snapped right by the thread what can I do it's the bolt with washer on

As I recall, the bolt is at least 100 mm of thread (but does the thread start deep down the hole making none of my suggestions possible?) how much is left on the bolt head?

If there's a lot of thread and it's loose maybe pressing a screwdriver onto the bit that's left will turn it out?
If it's been left, with Loctite then that probably won't work.
We are now into bodging...
If it has broken off deep in the hole, it's not engineeringly adviseable (as is none of this is)  but you may have to consider cutting another bolt shorter to get the torque then rotation required (45 Nm then 80 degrees) if there's enough thread to ensure it is tight.
Assume you used the new bolt already so old one would be the only option?
Otherwise at higher bodging level, and if broken where it can be seen, can a hole be drilled in the bolt swarf cleaned out and a stud extractor used (left hand thread to turn it out or worse, try to stick a drill with epoxy (won't work if any gets on the threads!)
I have had one bolt that was loose and it caused a clonk when taking up the drive, re-tightened with Loctitie.
At the very worst, it's either try the best to get some tension on it or another drive shaft?

Hopefully someone else can wave a Magic Wand on this?
 

I was thinking about a stud extracor but I've been told if it was tight enough to break the bolt in the first place it could break that too

How easy is it to take off tripod bearing and put on another shift it's the inner CV joint

Agree about the stud extractor but, if desperate and accessible you could always try it, very gingerly?
If the bolt snapped on tightening the bit that's left may, just may, be loose (you haven't said how much of it is left inside?)
Alan discusses the inner joints (if yours is the same design):

Not quite sure what you mean:

If you mean the inner joint is faulty, you'd need to check you can be certain to get the correct replacement part to fit to your existing inner joint?
If you want to remove the outer section and fit a different one into the tripod joint (if that's the design), I'd not be comfortable with that as the two components would not have been running together so may likely fail after a short time - your choice however, it just needs fixing, somehow?

If there's definitely nothing that can be done to get the bolt out, could you get a new/replacement  outer joint (as it's splined, that wouldn't cause a problem), repack it with grease, burp it to the correct dimensions before clipping the rubber boot and fix it that way?

There are "cheap" driveshafts on e-Bay e.g.:

This probably won't help you anymore but maybe others in the future. I had exactly the same issue, I had not checked the torque I found on the internet (45Nm) against Etis. Stupid, stupid as it is only 20Nm. So the bolt snapped, but there was about 5mm sticking out still. It was actually pretty easy to get it out. I did heat things up with a heat gun to counteract the loctite that was on the bolt, then put on my vice grip at a 90 degree angle to get it out.
