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?

Interesting. I'll check on occasion, see if it moves. The beauty of recording the torque setting
![]() 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 of ![]()
