02 Cherokee Shock bolt
 

A rear upper shock bolt broke off while trying to remove it. I have a
feeling the second bolt will do the same thing .
What is the best way to fix this? Do I drill out the piece of the bolt in
the frame and try to use an extractor or drill out the entire bolt and
retap?
Also is using an air drill any better than a regular electric drill?
Thanks

Whatever works for you, usually there's no way to center the drill.
I would blow it out with Oxy-Acetylene and thread chase it.

Dan,
All 4 upper bolts twisted-off on my rear shock project. I was lucky
and centered the drill on two of them. One good thing about the soft
bolts - they drill relatively easily. (Why did Jeep scrimp pennies on
something that certainly will need to be wrenched?) It is my
recollection that as I drilled, the remaining pieces of the bolts came
out on their own - although I may have tapped some with a small pointed
punch.

For the two which I drilled poorly, I tried two methods: The better of
the two was to slightly increase the diameter of the hole so that the
bolt slid freely into it. Then, I slipped a lock washer and nut on top
of the shock mount/weldment and tightend the bolt. That worked well
and has held tight for several months.

What I had done with the one on the other side was a bit more
labor-intensive. I rolled-back the carpet as far as I needed, using a
small drill, I made a pilot hole through the floor. Then I used a
(Dremel-type) hand grinder to cut a hole large enough for a socket
wrench, opposite the bolt's location. I put the nut and washer on from
the inside of the car. Next, I patched where I'd been grinding with a
small square cut from the adhesive-backed end of a roofing shingle,
before putting the carpet, etc. back in place. Good luck.

Oh yeah - I used hardened bolts. I used a regular handyman's 3/8"
drill.
