Thanks. Pretty familiar with fasteners. The issue is my pre-runner is 2wd and the torque specifications shown in Haynes manual for 2wd tacoma are not correct. The specs for 4wd and 4-runner look mostly right but some of them are clearly not correct for the stock 2wd pre-runner suspension.There could be a general torque specification list in the Haynes based of the size & strength of the fastener.
Be aware. The fastener size is NOT the hex size. Fastener size is based on the diameter of the body.
The head will show markings to indicate the strength of the fastener.
Metric fasteners have several strength designators. Sorry, I don't recall the specifics. Best for you to look this up. Then you will know in the future.
Rock62, i'm not concerned with the load rating of the bolts. I typically use Grade 8 bolts for most things even though it's overkill. Regardless, I've already put the truck back together and taken it over to local shop to do an alignment.Ok. Look at the head of the bolt. What number is stamped on it???? 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9.
