Axle Play - Bad Bearings?

Took off my rear wheels to replace my spring bushings and immediately noticed some play in both axle shafts. Do I need to replace my wheel bearings?

Also, I found a hole in the top of the passenger side axle tube. Is that for a vent hose or did a previous owner mess it up?

I have an 85 cj7 with an AMC 20 rear. Stock axle shafts as far as I know. Any insight would be greatly appreciated.

It is also apparent that the person who did the lift didn't install extended brake lines. That's next on my list.

Okay so it is a vent line. Are those easy to find on quadratec/4wd/morris4x4/etc?

There are shims nder the drivers side backing plate to adjust axle bearing end play. That is assumng the bearings are OK.

Do the drivers side shims adjust bearing play for both ends?

Yes, movement is transfered between both axles through the differential thrust block.

If there is slight bearing wear, you can remove a shim or two and check specs. (IF you still have the oem two piece axle shafts)
Outside of that, its bearing time. Keep the shims for that time.
The vent hose isn't special, its the metal fitting that you need to find that presses into the tube hole .....tact weld it in place as it probably wont stay.
