Mine are stock and are bolt with washer, I bought the truck new in 02 from the toyota dealership. The only time the lower ball joint bolts could possibly have been replaced was during the ball joint recall, it's possible that they replaced them and used the wrong ones. I'll check with the dealer soon to see what part# is for my truck.The stock bolts do not use a washer.
That's good to know, so the flange bolt might be a upgrade to what I have.A bolt with a washer will be a 10.9 bolt. About a a 150k psi tensile strength. A 12.9 will be higher, roughly 170
The recall addressed a specific manufacturing defect. The majority of the failures are due to lack of maintenance.I’d want to know what the failure rate is before I gave up on an entire generation of Toyota pickups. With all the first gen Tacoma’s out there, I can’t imagine it’s very high. Toyota has a recall to replace the ball joints, I’d like to think that would take care of the issue.
