Spicer 23-2 differential backlash question

[bmorgil]

Pabutler1, that is a great question. I would think that if that much backlash is present, there are one or more bad bearings, or the ring and pinion are worn, or both. The best way to do this in the field is first to do a good visual. The ring and pinion should show no signs of wear. There can be a real good polish where the mesh is occurring, but no indentations that you can feel with your finger tip or thinning of the teeth. Next you have to set it up. You measure the lash before you take it apart to try to get it as close to the way it was as possible WITHIN SPECIFICATION. It still needs to be assembled within specification. The assumption is made that when you check it before removal, it is within specification. If the axle has any kind of damage or bad bearings, this is seldom the case.

So if it is .024" either a bearing is badly worn and/or the ring and pinion is. If it looks good in visual and passes a good inspection for wear, go ahead and set it back up. If it is a bad gear set you will not get a good pattern. All this said, what is the intention for the vehicle? Parades or hard use? Send some close ups of the ring and pinion and the carrier bearing races.
