i noticed this when I did my wheel bearing on the passenger side and when I went to torque the axel nut. Shifter was in park. I assume my wheels should not be able to move. My passenger side axel rotated when I went to torque the axel nut. This shouldn't happen should it? By chance could this be a broken spider gear? 89 corvette with 3.07 Dana 36.

It will turn but should have some resistance. This is a test for the posi clutches to see if they are worn. Mine need about 60 ft lbs to break loose.

Oh ok. There was some resistance. Was a little worried. Car drives ok. Just had to be sure.

I had someone hold the brakes when I torqued for my rear bearing, you can porb use your p-brake if it's good.

Was the opposite (driver side) tire off the ground?

The torque for that nut is much higher than break-away torque of the posi

I'm aware of that. But there seems to be some missing information here. The OP said that the trans was in Park (locking the driveshaft, and therefore the pinion and ring gear/case), and the RH axle (halfshaft) rotated (clockwise/forward) while tightening the outer spindle nut. But unless I'm having an "end of a long day" bit of fogginess, if the passenger side halfshaft rotated, that would rotate the RH differential side gear. When that gear rotates, it causes the two spider gears to rotate, causing the LH differential side gear to rotate (in the opposite direction of the RH side gear), causing the LH halfshaft and rotor/tire assembly to also rotate, but backwards.

If both rear tires were off the ground, then things make sense. If the LH tire was on the ground while he was tightening the RH spindle nut, then there's something amiss.

Just trying to understand what the OP was doing.
