Driving down the street Saturday to save my Kid who ran out of gas and when I backed off the gas pedel to stop the rear end made a loud scream, I lightly got back on the gas and it went away.. but I had to stop for the light so I took my foot off the gas then it went boom !

Screach and ground to an immediate halt...luckily not towing the trailer and the person behind me was able to stop..

Had to get it towed home...just a few blocks, looks like the pinion nut came loose and then came off.
I had to change the Power loc unit about 40K miles ago, when it blew up..and left parts everwhere, so I guess it was only me to blame...
Looks like everything is trashed, I think even the housing is junk.
