These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

12 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • 986Forum: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Anyone have a slick removal technique? I can drill and chisel as well as the next guy, but if someone has a slick trick I'm all ears.

POST 2Original post

First some Kroil several times over 24 hours.PB Blaster or ATF second best choice. Mig weld a bolt on it ?But you need to be very good at precision welding.Hold the bolt in a fixture in the correct position about 2mm away from the old phillips head.Do not forget to disconnect the battery!! Left hand thread easy-out ?

POST 3Original post

You might be able to take a good hard punch and peck it out after the Kroil or PB Blaster.

POST 4Original post

Heat up with torch, when hot spray with pb blaster, leave overnight. Impact screwdriver. Worker for my rotor screws.

POST 5Original post

+1 on impact screwdriver, that's how I got mine out. Replaced them with stainless ones from Lowe's and I put a little antisieze on the fir next time. I got the tool from O'Reilly auto parts for around $8-10.

POST 8Original post

Take a cold chisel and whack a slot all the way up to the outer circumference of the bolt. Then, put screwdriver in the slot, angle it and hit it with a hammer so it applies force in a counterclocwise direction.

POST 9Original post

Quotes source post: 445569

+4 on the impact driver.

POST 10Original post

use a dremel and cut a deep slot into the screw head and use a large regular screwdriver. also after cutting the slot into the head be sure to tap the screwdriver deeply into the new cut to ensure a good bite for the blade.

POST 11 / ORIGINAL POSTEROriginal post

+5 On the impact driver. I've never used one before and wow! The screws came out with a few taps of the hammer, even the stripped ones! Why didn't I know about this tool already? Man that saves a lot of time and work! Thanks folks!
