Ball Joint Bolt Replacement Strenght

Got my FCABS, Control arms and Inner Ball Joints all out and it appears at someone during it's lifetime when someone replaced one of the inner ball joints they used (2) Triple Square Bolts instead of the standard M12's. Yes, it was very difficult to find Triple Square Sockets anywhere in down to remove the old ball joint.

My question is I looked up pricing for 2 Bolts and it's $10 per bolt, do you think a M12x150x70 from Fastenal is equal quality?

I'm looking for Grade 8.8 and Grade 10 Bolts, and I have three finish options Plain, Zinc and Yellow Zinc.

These bolts are a 1/3 of the price of Factory Bolts meaning I would replace all 4 on both sides.

Any thoughts would be helpful.

Thanks,
Joe

Re: Ball Joint Bolt Replacement Strenght

I've personally replaced many bolts with their equivalent from fastenal. As long as the size and grade are correct I don't see it being a problem at all.

For some reason, I think you're thinking of the exhaust flange bolts that are made of incolnel and cost $20.

These nuts, OE, are $1. Also, as they're difficult to get to and tighten, I think you'd want the OE nuts...especially as they seem to have a built in flange and are self-locking.

Doug, that is the wrong picture. The XI has inner ball joint that is separate from the Control Arm that is attached to the XI Front subframe with two bolts.

Here is the link for the bolt's I'm reviewing. Most places are $9 online, I'm figuring $15-$20 at Dealership.

Bolt 7 Is the Question, First things first I have to find someone to press out these old bushings!

I'm so ashamed of myself. Still...expensive bolts are the cheapest expensive gift you can buy your car.

I totally forgot where I was...just browsing new posts. Just another reason for rwd!

I sucked it up and paid $9 a bolt and bought two to replace the two triple square bolts that were installed.

All is well!
