Help! Bolt threads in Steering Knuckle Stripped
I was doing a brake change. I went to undo the last bolt (two per side/caliper) and the bolt backed out taking the rusty threads with it. Now my truck is not mobile and really need to fix this! I only have one caliper pin bolt that will thread on the passenger side knuckle.
What are my options? Not sure if I can trust a heli-coil when it comes to brake threading.

Okay so far I have found some info...
My options look like...
1. Self tapping over-sized pins
2. Heli Coil (sounds safe?)
3. Replace knuckle at over $400
Im going to call NAPA and Lordco to see if they have the self tapping over-sized caliper pins. Also will bring a pin in with me...
Anyone know the size and threads?
Apparently this is a really common problem.

Heli Coil is good and safe but more work than need unless it is last resort.

Update:
Went to NAPA and got the oversize self tapping caliper bolt. (Part number 675-1539) The price came to $40 with tax.
Worked great! Turned the steering so I could get my head in-behind the knuckle to make sure the hole was lining up. Everything was lining up so I put the blue Loctite on that it came with and threaded it in nice and snug. Was REALLY careful not to over tighten. I didn't have a torque wrench but it says to tighten to around 25 ft/lbs I do believe.
Success! Thanks guys! Another crisis diverted LOL
