Question to my new installed spider/sidegear on Chrysler 8.25

RustyRatRod said
1) My bad. I thought it was a track lock.

2) No, not on an open diff, but yes on a track lock.

3) How do you know the slop observed in the video is within spec?

4) Yes, see my #1 answer.

3# I emailed Richmond Gears an ask:

Is it normal that the pinion gears not going totally tight on the shaft? it seems to be a little bit loose and wiggles on the shaft.

Answer: That is correct . There needs to be a tolerance in order for oil to get between mating components.
