Rear axle. Preload on pinion shaft bearings. WHY?

[Guest]

Sorry for my ignorance...

 

Can any one explain to me what is the reason for this preload on the rear axle pinion shaft beraings?

 

Is it as important as the manual says?

Is it important for the bearings or does it have to do with the relative position between the pinion and the gear ring?

 

Thank

The bearing will just about instantly die without it.

 

 

 

I think.

Preload is important to the bearings, as backlash is important to the R&P mesh.

bearing preload makes sure that the bearing stays together and that the bearings rotate. If you don't set the preload it's likely the bearings will skate in the races, or get cockeyed. Bearing death is iminent without the proper preload.
