This is really beginning to piss me off. I've had a second axle bolt failure, this time on the other side. Apparently there is a group of engineers and analysts somewhere in the engineering staff at FORD that has no idea of Fracture Critical Parts, Single Point Failures and redundancy of fracture critical parts. If a single bolt fails and renders my vehicle as unsafe to drive, then there should be redundant fasteners. FORD you need to conduct a Failure review board and determine the root cause of the bolts shearing and issue a recall and have the affected parts replaced. I'm not sure how the design of the axels on the Explores are designed but I have read that those axle bolts fail as well. As soon as I finish this post I will be writing to NHTSA to submit a compliant.
