Preparing to remove studs

Keep in mind, once you get studs out do not use a tap or a die to chase the threads.

Ford used a higher tolerence thread in the block and you will reduce the thread contact area.

I use a 90 degree scribe and hand clean the threads.

Right on a standard tap will over size the holes. You can take a old stud and cut 2 or 3 slots in the thread with a thin cut off blade in your hand held grinder. That will clean the threads well.
 
1. I purchased an inexpensive stud remover from CARQUEST that works with an impact wrench and have never broken a stud since. For studs that are rusted to a smaller diameter you need to be a little more diligent with reduced air pressure to break the rust lose.

2. I, like George Miller, use old fasteners but I just grind a small angled flat spot on the end and use that with penetrating oil to clean up threads. Case in point, I had some well rusted up backing plates that I used this method on the break adjusters and with a little work I was able to turn the new ones in and out by hand.
 
James G I saw that chart on penetrants compared to the 50/50 mix of acetone and auto trans oil,I always use the 50/50 mix and have had great results.

theres a lot of good info here regarding prep with penetrating oil and tapping. Welding a washer and nut to the broken off base works really well. The one thing I have not seen mentioned yet is a tool made by Snap O

n for removing studs. Its a threaded collett with an outer sleve that you can attach a socket to. Then use an impact wrench. I find I have broken fewer since I started using this tool.
