<VV> Loose axle

[Doug Mackintosh]

Hugo, the wheel bearing allows angular movement since the suspension arm/bearing mount does not stay in alignment with the axle shaft as the suspension arm moves. As a result, when the tire is pushed upward (e.g. when the car is resting on the tires) the axle assembly can rotate about the wheel bearing which will push down the differential end of the axle. So I think when you rest the car on the ground it may push down at the differential end and make the slop disappear. Not sure how much force there would be at the differential end, but likely enough that you would not be able to push it with your hand.

Alignment? What alignment? Are you saying thew rear wheel alignment
will change if there is no engine or drivetrain in the car? Because the
weight of the car will push upwards on the outer end of the axle shaft
and downwards on the inboard end? Is that your point? I see what you
mean, but there's a double taper roller bearing at the outer end, isn't
there, that I would have expected to hold the whole lot in alignment.
Why doesn't it? Or is it a self-aligning bearing? That might explain why
the tapers look the wrong way round? But then again, if it's
self-aligning, it shouldn't be exerting any force in ANY direction. This
all seemed so simple till I started thinking about it!
But when I grabbed it earlier, I was pushing more forwards and
backwards rather than up & down, as I was reaching under the car to do
it. I'll try it again tomorrow with more force & see if I can get
anything to move.>>
