Rear not working on an 1G AWD

[my_gst95]

I recently bought a 1g awd talon and it had a probelm I was going to disregard...but it has got me thinking. Maybe I can get some ideas from you guys:

When the previous owner was driving it on the freeway, the rear suddenly stopped working, turned into a fwd car basically. Before I towed it home, I took a quick inspection of the rear 4bolt and it's axles, nothing looked physically bad, I couldn't shake either of them to indicate if they had busted. The transfer case and tranny were recently replaced.

Anyway, I'm dropping the transmission tonight to see if the output shaft spins when I turn the tranny in gear by hand. I'm hoping it's an issue somewhere in the rear because I've never felt a 1990 awd transmission shift this good. Having to do work and replace the center diff would suck compared to just having to replace the pumpkin or one of the axles.

Just thought I'd throw out the problem for some ideas of what it could be.

Thanks,

I think I figured out the problem:

When I manually spin the transfercase (the hole that the output shaft of the tranny plugs into), it doesn't spin the part that connects to the drive shaft. Would improper gear ratio's cause this or is it just a faulty transfer case?

The 1990s came with a 3-bolt rear. If you have a 4-bolt check to make sure it came from a car with the same type of tranny as yours (i.e. Manual for Auto) as they had diff ratios and would seriously f-up your tranny's VC if the wrong one was used.

Most likely what happened, toasted the viscous... Does anbody know if the auto/manual rears have different #'s on them? Or any other way to tell if the rear was out of an auto or manual car? (without taking the thing out)

The tranny works/shifts fine. I can put it into gear by hand and spin the input shaft, and the output shaft spins accordingly. I'm just not sure how the XFER case busted to the point where it doesnt spin the drivetrain and the rear. The 4bolt was swapped from another manual.

Strange... Are the splines stripped or anything like that? Wouldn't surprise me if half of the damn things didn't work from the factory! jk :laugh:
