Is the EA82 D/R viscousily coupeled? I took the sedamn out yesterday and after a few hours of wheeling no more 4wd. No noises to indicate damage just stoped. Any thoughts?

AFAIK they are not viciously coupled. It's all gears. I have never heard of one losing 4WD, I have heard of gears not working and I had one that reverse died, but never broken 4WD. Hmmmm, I dunno? Maybe the linkage broke and it looks like you're in 4WD? That's weird! Hopefully someone else chimes in! Good luck!

Did it loose the front or rear drive of 4x4?

I have heard and been warned of stripped outputs on these. I have also heard of people running these in 4x4 as an RWD for years with success. I'd lock it in 4x4, and then get under and try to turn the driveshaft.

our old Subaru we had years ago would just pop out of 4wd

You may have broken a CV in you're rear axle. Even breaking one on an open diff will cause all rear drive to be gone.

 

My second guess would be a stripped rear output. it is only about 1/8th in nubs that engage via the 4wd shift collar. not much really, they can strip

 

But check both rear axles first. Put the car in the air, hold the inner CV cup from underneath, and have someone try to spin the tire. you may find one of the joints will just be broken inside, and spinning.

Cool, thanks for the feedback. Ill check it out soon. I hope its something simple. I have a spare trans but im hoping its something simple. What confuses me is there was no pop grind or anything indicating 4wd is gone. Hopefully its just the linkage or something. Ill update later.

 

Thanks again.

Yep. it was the right rear CV joint. I think it did it here:

 

Too much droop with the new rear coils and 4th great slinging mud and water may have done it.
