And to be clear here, it's NOT wear that's the factor with the bearings. It is leaching of the calcium in the white metal due to Eu olis being magnesium rich (That's the story and I'm sticking to it). If it were just wear they should last almost forever. That's what lubricant is for. It's like the difference between tyre wear and a puncture. Different failures.
Stretch bolts can be re used if, like mentioned, they have been measured and are in spec. I don't know what this is or how to measure it so I put new bolts in. I think I would leave it in bits and hire a car for the week personally. I don't know the physics of stretch bolts in detail but my worry would be that if re used they could actually have been tightened but within a few miles, simply come loose. If they can be tightened slightly more then the 90 degrees and use a little more stretch then perhaps that is a solution. But just doing the torque plus 90 degrees again worries me. Gut feel not science.
