I have replaced the entire front end of this truck, all ball joints/upper control arms, sway bar end links, inner/outer tie-rod ends and connector.

After about 3 days of driving, an alignment, normal stuff, I started hearing a slight rattling and turning felt off when turning the wheel to the left. Heard a slight squeel too, so thought maybe the brake pad clip had gotten damaged somehow. I jacked up passenger side, just out of habit I wiggled the tire and it moved. This is not good. I removed the tire, discovered that one of the 3 bolts is now missing. I have to drive on a lot of dirt roads to get to and from work/home. My problem is, this is my only vehicle. I don't have another to take one of the other bolts out and go looking for one to match. I need to know what size so I can go get some and replace all 3 of them with new ones.

Please help!!!

Oh, 2002 S10 4WD with 4.3 v6. I don't know if it is a zr/zt or whatever the other available options are.

It's a metric bolt. If I remember right they're M10-1.5X30

What about the thread pitch or whatever it is called ??

 

[oldeerslayer]

That's the 1.5 part.
from the Bolt Depot

The thread pitch is the distance between threads expressed in millimeters (measured along the length of the fastener). For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm.

10mm is the diameter and 30 is the length

Thank you. I am not great with metric

15mm socket fits the head of the bolt, if you haven’t removed them yet.:

Mine are 18mm bolt heads

Maybe that's why they loosened up? Possibly not the corrected hardened bolts that GM used. If mine were coming unscrewed I'd buy 3 GM ones even if the price is a bit steep for peace of mind and then torque them to the correct spec with some blue Loctite on the threads.
