hello,

With my 4Runner up on jackstands, no matter what drive mode it is in (2 wheel drive, 4 wheel drive, locked, unlocked, reverse, etc.), only the Lefts wheels rotate.

The Right wheels remain NOT rotating AND I cannot rotate either Right wheel by hand.

Although it is common to see only 2 wheels on one side rotate while in 4-wheel drive mode, I am surprised the Right side wheels cannot be rotated by hand.

Why are the Right side wheels unable to be rotated by hand? Shouldn't they spin freely by hand?

The only thing I did recently was rotate wheels front to back and back to front for more even tire wear. Until I did this, all 4 wheels rotated while in 4 wheel drive mode.

The jack stands are not touching the wheels.

Are the Right side wheels locked for some reason? Why?

Any help in explaning this situationo is much appreciated.
