Help!!! Need smart mechanics here asap!!

2 problems:

1st this bolt. I finally broke thru and bit snapped. Second bit offset also snapped. I've tried everything. Diamond dremel bit does nothing. THe bolt is a 10.9 grade so its hard. I think I also work hardened it from smacking with a punch so now its UBER hard. Ive heated/cooled and nothing. I dont want to destroy beyond use or order a new knuckle.....HELP!!




2nd the chip in my hub. How would you dress this up? a little sanding to remove any weak chrome?

Looks like you are deep enough to start an extractor in there. Try applying a little heat from an oxy acetylene torch. Once its got a slight glow on the knuckle try cranking it out. I would also suggest taking it to a machine shop or auto shop and let them waste drill bits and gas working it out if this don't work or you don't have access to a torch

So you snapped the strut attachment bolt off in the upright (likely due to corrosion) and would like to extract / drill the remaining bolt out to fix the situation.

An extractor is not generally going to work in this situation. They work for torque-snapped bolts where the remaining "stuck" portion is not corroded or otherwise frozen in the piece. If you still want to go that route you need the biggest extractor you can get and a manual impact hammer might help.

If you have broken drill bits off in the piece you need to get those bits out because you can't drill them. Sometimes they can be pried out or worked a little with a small punch and pulled out with a magnet.

If you need drill bits to go through that tough stuff, I suggest you pony up for a cobalt set, that will generally cut through any standard grade bolt.

Of course you can also heat the upright like mixedgas401 said.

depending on your skill... keep working, take it to a machine shop, or get on ebay for a replacement

I guess I should have mentioned that the extractor is only going to work with some heat. It was late for me last night.

BTW I picked up a nice extractor set from Autozone. It is OEM brand but it has actually worked and held up better than my snap on set. And the drills are pretty tough too. I live in north east ohio and yes we use salt and brine so in my line of work a solid set of extractors is a must

soak the bolt in industrial strength penetrant, silikroil/aerokroil would be ideal. PB Blaster might do a little bit. You need to let it sit and soak and keep reapplying penetrant. Try filing the broken end of the bolt and redrilling from that end. Make sure you start with a flat surface though and put the punch back in the toolbox. Clean up the OD of the hub with a file or sandpaper just enough to remove raised metal, dont go crazy. Chase the splines with a triangular file, the fit with the axle is very tight. good luck-

This is *exactly* why I drilled the threads out on the knuckle and replaced the original bolt with a longer one and a lock nut + Loctite on both of mine! I dealt with this on one knuckle and it took me HOURS to drill that S.O.B. out. I wish you luck and patience in your quest to fix this problem, sir... you're going to need it.

A tungsten carbide cutter on the Dremel will work through this stuff, just takes LOTS of time. Unfortunately, the shape of most carbide cutters for the Dremel are not conducive to the tight quarters that you are dealing with here. Ran into this issue with my exhaust studs too when I snapped 2 of those... same fix, got them out and replaced with through bolts and nuts + anti-seize. Any of these little fvckers breaks again on me, the halves of the bolt(s) just slide out the opposite sides and I move on.

The used knuckle may be the best route in this situation though!
