Just wondering if the comment I heard today was true or not. I was told that if you pull both axles out of your rear end install one and turn it your rear end will no longer work until you re-align the gears. The reason for me asking. I pulled both axles to replace bearing and seals. When I installed each axle I spun it to be sure the rolled freely. Now that I am done I realize the output does not turn. I have no history on this rear end it was a spare so I have never used it.

One other note this is NOT a Posi.

I don't think there's a danger as long as the center section cross shaft was still there, like it shold be on a pontiac axle, but I could be wrong. It happens on c-clip axles since the center section shaft is removed... side gears and shims fall out.

spin the driveshaft yoke and one or both axles should turn. If you're spinning an axle, the yoke may stay in place -normal.

Thank you I rotated the yoke and sure enough the axle did turn.

One new question the drawing shows a gasket I have a metal shim but not gasket does any one what thickness to make the gasket?

Rule of thumb would be .005 less than what it would take to fill the gap so that there is pressure to hold the bearing. Any size within reason that is smaller than the gap would work.
