Changing to right hand threads

I find the hammer method the easiest. Saves the chance of an axle seal leak. I use a BIG hammer and just tap them out. Use a socket and/or a stack of washers along with the lug nut to draw the new stud head back down against the axle shaft flange. Try your local tire store. Some have a good stock of replacement studs and nuts.

This method worked for me. It did not take a ton of force to get them out. Just be patient and go straight.

As was also mentioned, the length of the stud will come into play. If it's too long it won't fit out the back side. Same goes for installing the replacements.
