95 awd diff questions

[1stGenRocks]

Ok so I think I broke my center diff or viscous somehow.

Heres what it does
On a lift you can turn either front wheel without it spinning the other. The left seems to spin something inside the trans the right just seems to spin the axle. While doing this you can hear clicking like stripped gears inside the trans. Once in awhile it will grab and then the 2 front spin in opposite directions like normal but it doesnt spin the back wheels at all.

If you spin a back wheel forwards sometimes all 4 spin and sometimes just the rear 2 and the driveshaft

If you run it in gear while in the air occasinally the front wheels catch and will spin but most of the time just the rear. However you dont hear the stripped gear sound.

Driving it it doesnt feel like any power is going to the front. The back end spins and slides even on light acceleration. Occasinally you get a popping grabbing kind of noise from the front.

Any chance this is just an axle problem? It seems to have full power none of the clutch slipping feel that I've heard related to having a broken axle.

I'm still searching and reading but I havent found anything quite the same as mine and I dont understand how it all relates quite well enough yet to figure it out. I know I need to pull the tranny anyway to replace my ACT clutch disc that the damm spring popped out of but I want to check anything neccesary before pulling it.

I also have 2 1g awd trannies with syncro problems. Any chance I can use the center diff from one of them as long as my 2g bellhousing is okay?

any 92-99 diff is compatible

Yeah I was going to say it sounds like the center diff to me. If you flip a U turn with a busted center diff the car will jerk slightly and you will hear a clunk clunk sound. I just had to replace mine not to long ago.

Glad to see you got it fixed.

I knew i should have pulled the trans apart the rest of the way and checked the front diff too.

Still doesnt work. I can put it in the air and spin the front seperatly from each other and they dont spin while in gear. Its got a kind of rotational noise that starts at about 20mph and gets louder as you go faster if you drive it.

Not sure if it means anything but the diff I put in was from a 92 laser 6bolt/4bolt. However where the 2g diff has hatch marks up by where it bolts together the one from the laser had the marks by the gear. Is this my problem?

Ok so I did some more checking on my parts trans trying to figure out how it all works together. I'm thinking my problem may just be in the center diff since on the parts trans if the center is out you can spin the front however. Heres a picture of my broken 2g diff the hatch marks on it are pointed out in green. The other diff that i put in has the marks at the red arrow. What would the trans do if I put a 91 diff in it? This was supposed to be a 92 diff but I got it used from a friend so you never know.

I can run it in gear while in the air and its quiet, its only noisey if all 4 wheels are rolling. Whether its in gear or not.
