front diff. problems?

hey guys..

so if you guys look at last thread you'll see that i changed my axle shaft recently.. and it was not as painless as i had hoped..

the reason i changed my axle shaft was because i was starting to hear a slight grinding-like noise along with what i can only explain as shuddering metal? and i hoped that the axle shaft i've been neglecting to change was the source of that awful noise. and turns out.. it wasn't..

so since it was time to change the diff. fluid i went ahead and started to take the cover off and didn't find anything out of the ordinary.. except i saw that there was a lot of play in the gears.

when i had the front end up in the air.. i was able to move my wheels from the 12 o'clock position to about 1 o'clock and going backwards to the 11 o'clock position. is my front end on its way out? what do i need to check/fix/change/replace?

any insights would be much appreciated.. thanks for your help!!

I would guess unit bearings before ring and pinion. Mine moves a lot more than that but I have 270k miles on my front gear setup. Get it up in the air and figure out where the noise is coming from

rotating the wheels back and forth doesn't tell you too much about the condition of the ring and pinion.
check for side to side play of the ring gear and carrier, hold the PINION yoke steady and check the rotational play of the ring gear(backlash), you'll need a dial indicator for that.
check for movement of the pinion in the bearings.
