how much play should there actually be in the pinion yoke?
side to side = none
in and out = none
rotating = 360 degrees
with the rotating part, what if the tires are on the ground?
Yeah it will still have play from the backlash between the ring and pinion.
A detroit will have tons of rotational play, an open or gov lock will have much less.
Seriously, how much? Great question, because my 14 Bolt on jack stands with a Detroit locker, I can turn the pinion yoke from the clock positions of 10 to 12 before the locker engages and both axles turn. Then other times, It's right on the with no slack.
detroits are like that. I can turn my pinion over 90 degrees some days. It is called dynamic backlash.
in the front I can turn it about 90* and in the back about 3/4 in
thats with stock 10b, is there a way to make less backlash?
Yes but you need to measure yours first.
Off the top of my head a 10 bolt should .006 - .010
haha so u mean my dana 60 rear pinion shouldnt slap back and forth cuz teh bearings are so wrecked out?
The pinion should have a little bit of "play". If you measure back lash at the yoke it should be double what it is at the ring gear. For example, if it is .008 at the ring gear it should be .016 at the yoke. If there was so much backlash it would be a problem and you could most likely tell when you are driving.
