Which is the carrier culprit ?? AMC 20

I have a bit of slop in my spider gears. What is the most common places for wear, Carrier pin, carrier pin holes on carrier or roll pin. My big concern is the carrier holes are the culprit but shouldn't there be a little bit of play in there to slip the pin in ?? Otherwise the spider gears look clean, so does the ring and pinion

The pin should be a slip fit with no movement in the carrier. Movement can cause the retaining pin to shear, allowing the shaft to slide out. If the slop is bad enough, it can also crack the carrier. A slight movement can be monitored, but if you have definite clearance between the pin and carrier, then the carrier should be replaced.
"Slop" in the spider gears is common and will not hurt anything as long as there is no damage to the teeth and the thrust washers are serviceable.

Thanks for the reply, I'm gonna see if that roll pin is worn, looks fairly easy to punch through.

I highly doubt the retaining roll pin would cause what you are seeing. I'd bet it's the cross shaft itself. I had one worn so badly where the spiders rode that I couldn't get my Aussie locker set up within spec. Hopefully you have 2.73 or 3.31 gears so you can remove the shaft without having to pull the carrier out and remove the ring gear to inspect it (Not sure if the shaft will clear 3.55 or 3.73 gears).

I have 3.55's and it looks like that shaft will slip through the carrier no problem, I am able to get to the roll pin from the left of the carrier(punch it through)

Should be able to inspect it without issue then. The wear will be pretty apparent if it's there.

The word "pin" should be "shaft" instead.

Same thing here.

Worn carrier shaft and bent roll pin

I suppose this is what a well worn carrier shaft looks like and bent roll pin
