5/16" bolt in a 3/8" hole for upper ball joints?

71 C-10


Just getting ready to install the upper ball joints when I noticed the Moog parts uses 5/16" bolts.

The old rivets were 3/8". The A-arms are a tight 3/8", they were powder coated. It wouldn't take much to drive a 3/8" bolt. That said the ball joint plates won't take a 3/8" bolt. So by using 5/16" bolts there's some slop in the A-arm.

Maybe it doesn't matter, thanks to a nut and cotter pin? Heck I don't know

Is this common? are they the wrong ball joints? Install as-is works fine?Thanks.

I've noticed that also, just get them tight and it's going to be aligned anyways. Once the pressure is on I don't think it's going to move

You used lock washers, right?

I believe it was in the installation specs to use the locktite. No biggie it can be redone if you so chose.

Interesting. I'll check on occasion, see if it moves. The beauty of recording the torque setting Should be easy enough to change later.

My boys showed up yesterday, and the extra 400 lbs + the engine made it easy to install stock height coils, no compressor required. Looks like I have a compressor to get rid ofI'll never use it.
