Rear drain plug stripped

I was going to drain the rearend while I changed out the rear wheel bearings and it looks like the previous owner rounded the hex bolt off with probably an 12 point socket. I dont have a welder but thought about taking my dremel and cutting a slot in it and use a screwdriver bit on my 3/8” wrench to try and remove. Any of you guys done or should i take it and have a bolt welded on to it?

 

I had a castle nut welded onto my front diff drain plug (that stupid allen-head one), and it worked out great. Local welding shop charged me only $20, and I felt it was well worth it. So I'd do that if it were me

 

I use an air chisel, create a dent into the plug, then walk the plug loose.

You can use a large chisel and do the same with a big hammer. You will need a new fill plug either way.

 

these are pretty soft metal so you may be able to put the next size down socket on there and hammer it on, air chisel is another great suggestion those things are a game changer for anyone who works on old or rusty vehicles. If it was exposed like the fill plug id say put a pipe wrench on there but the guard around it won't let you get access

 

I tried a 15/16 and it cant grip it. I tried hammering a 7/8 and couldn’t beat it on. I have an air chisel but dont really understand how you guys are describing to use it. Would i make a dent on one aide and position the air hammer to move it backwards like a rachtet would taking it off.

 

If enough clearance to hammer 7/8th

this might be the ticket

I will take close up pix of my set

Yeah the bolt extractor sets that ControlCar posted are my favorite things. Helped me take out 2 rounded lugs on a BMW. They are a God send. Hammer them on and then use a breaker bar to break the nut loose.

 

Pretty sure my drain bolt was 19mm

looks like the biggest one fits

Says on the B extractor

let everyone know if helps

 

I know the head of bolt is 24mm. That isnt to say the actual bolt is a 19mm. Im guessing these socket’s reference the diameter of bolt and not the hex head.

 

Dang

so will need to source Large extractor

 

7/8 is the next closest size you'll likely have in your tool box.
Technically, 15/16 is the closest. But 15/16 is so close to 24mm, it will likely just round off too.

But give 15/16 a try first, just to see.

 

I have given the 15/16 a try but it didnt work.

 

I should add, unless you are using a 6 point socket, it's useless.
A 12 point will only make things worse.

Maybe cut/file down to fit a 7/8"
Other wise, you are going to have to find an extractor or weld a nut to the stripped bolt head.

 

Take it to a muffler shop or a welder, pay the $20 and have them weld a nut to it and call it a day...save yourself the head ach

Shoot, I'd do it for free if we where close to each other..lol

 

I can get a nut welded on, heck i even got an old lincoln ac/dc welder but i have never struck an arc. Dang i need to live more.

 

Kinda like this, make a indent, then using the chisel rotate the plug loose.

 

+1 to welding a bolt onto the end. I would just get it done and move on. How much time do you want to spend fighting it?

 

Glue a nut to it

 

I got a buddy coming over in a couple days to weld a 3/4 nut on it. I tried with air hammer but not being fully committed I gave that up after metal starting moving but bolt wouldn’t budge.
