Cool.....thanks guys

I've got 3 bolts coming which should be here next week. I'll see if they already have a stripe of threadlock on it when they come in.
Last year I had a bolt break and the other 2 bend. They ended up replacing the differential input shaft, coupler, diff seal and bolts. After waiting a week for parts, it still took them a couple of days to get the work done. Then a couple weeks later it started vibrating again.....got underneath it and saw that the bolts were backing out. Took it back to the dealer, the mechanic claimed he torqued it correctly (yeah, right!) and they replaced (supposedly) the bolts again.....anothr couple of days down. When I picked it up the second time, the service manager asked me if I realized how much more the rear tires were worn than the fronts, smiled and said: "You need to stop taking it to the track, brother" (which I never have, by the way).
It'll be a lot easier, quicker and convenient to just replace them myself this time. That way I can be SURE that it's done right, AND I don't have to worry about somebody possibly getting a wild hair and trying to void my powertrain warranty due to allegations of abuse.
