Rear axle making weird noise

[julianramirez1005]

I’m not quite sure if I should post in 60s or 80s forum but I’m getting a weird noise from my rear axle from 80 series. It’s also accompanied by some grinding while on the road. The axle turns freely and I’m fairly certain the e brake is not seized. I took the calipers and rotors off and as I turn the hubs by hand they are making a weird click/clunk as I turn them. I would assume it’s not supposed to make a noise at all and should turn quietly and smoothly.

I’m not sure what air lockers it has but it has them. I did blew some compressed air in the port and they lock up as intended.

Gonna pull these apart and maybe do wheel bearings and rebuild soon. But I just wanted to ask y’all’s opinion of what this noise is.

I have spare front and rear diffs from a fj62. Are the third members interchangeable?

that doesn't sound right, you are correct. I am sorry I don't have an answer for you, I am confident one of these guys will know what that sound is. Does the sound remain the same when the locker is engaged?

Bump to the top.

Every open differential axle I've ever played with has sounded like that when turning the hubs by hand with no wheels on them. The spider gears are pretty notchy/clunky straight cut gears, and are very loud as a result if you start turning them. Normally when both wheels have traction and you're traveling straight, the spider gears inside the differential are not turning at all.

This is really good to know. Fingers crossed that I'm just paranoid
