First of all, excuse my typo of axle, which I can't edit now.
We are running a 6-wheel drive with a 1/8 drop on the centre wheel, with AM performance wheels geared quite aggressively for 15 and 7 ft/second (calculated including efficiency loss). Performance wheels are threaded for 10-32. Each wheel had 3 grade 8 10-32 bolts in them.
About 10 minutes into driving yesterday, we noticed VERY limp chain. Upon closer examination, we found that the entire sprocket assembly had sheared off of the middle wheel. All 3 bolts had sheared. We promptly replaced the wheel with the bolts ends lodged in with our spare, pulled all the wheels off, and added 3 more bolts to each wheel.
Today I drove just as aggressivly, and we haven't had any issues (at least not with the drivetrain
). I suspect they sheared when I was braking while downshifting, but I'm not sure.
