what bolt for balljoint pinch?


Recommended Posts

I was dumb and used a 12point socket for the balljoint pinch bolt and now its rounded off. In the case I can get it off with a 6point and some heat, what bolt is used there?

 

Lemme guess... 10mm x 1.5 pitch x 40?

 

Can I get away with grade 8.8, or should I seek out a 10.9?

 

Thx!

thanks!!!

 

When I removed that pinch bolt, it was so tight I feared snapping it. I could see the bolt head twist but not the thread end turn, by marks.

 

I drilled into the thread end directly, as centered as possible, one inch deep with a 1/8" drill, to relieve some of it's grip. If I was slightly off and it touched the threads, that may have allowed some Pblaster to infiltrate and allow easier removal.

 

I just didn't see a ready way to recover from a snapped bolt there, so I did it as a preventative measure.

I could see, in a "pinch" so to speak, drilling the bolt completely out, and using a correct size bolt and lock nut.

 

All?

 

All Subaru bolts/nuts are 1.25 thread pitch, which I am told is "standard" for a Japanese car (Honda etc.), only in America (American made metric) do you get vehicles with the 1.5 thread pitch.

PITA if you ask me, I have to travel about 6 miles to get them, while American type metric is available to me about 2 blocks away.

Away with the 12 point sockets, I am in the process of replaceing mine with six point. I had the same thing happen to a oil drain bolt on a chev. with a 12 point but was able to take it right off with a six.

I heated the knuckle up pretty good last night but couldn't get the bolt to turn. Now I have one bad bolt head and one melted balljoint boot :-\

 

I drilled the other side last year, maybe I'll have to do the same to this side.

if I may make a suggestion - try melting some parifin wax into the gap on the knuckle...

heat the area of the pinch bolt and then drip some melted wax into that area keeping the heat applied so the wax can seep into the threads. May help.

the other half uses this method on his work truck frequently when PB just wont cut it.

 

you should be able to get the parifin wax at your local grocery store - it is used to create a wax seal when making jellies and jams. a brand name is Gulf Wax...
