Ok weird stuff on my 90 awd talon.

[AL92]

I got a 91 talon auto.It would not move forward or back at first thought trans was gone but then we put it up on jacks and driveshaft was turning but bad noise from passenger side rear axle. Close ispection shows sheared off rear axle. So ok understand thats one reason car don't move. But now have both front wheels up in air and back wheels.
I go to turn the front wheels on my 90 talon and if you turn one front with both in air and back wheels in air with broken back axle only one front turns.

Now on my 91 talon awd with back wheels on ground and good axles when you turn one front wheel the other turns. Is this only cause the 90 talon has its back wheels up and broken axle or does this point to broken front axle or mabye pooched viscous coupling.The car was obviously badly abused before I got it to shear a back axle on a stock auto car. But anyway its my race car.

So if I put in that replacment back axle the car should at least be rwd?


And it that normal for both wheels to not turn when you turn one on the front with back ones up in air ?

Never drive an awd with only front or back wheels working.Big no no.
You will screw up something else.
I would take a look at your front axles.
Im not a transmission expert but im pretty sure the viscous coupling only holds the output shaft in place for the rear tires.Do not quote me on that.
Somebody please correct me if I am wrong on that.

Not sure if this matters but my 91 auto awd has abs and thus has no limited slip.
You could not get both in 91. My 90 as far as I know has lsd. So mabye thats why the wheels don't both turn on the 91 auto awd.

The car is not a street car its a race car only. trailer to track and home. It will be running 1/4 miles not street driving .Still want it to have working awd. So will replace viscous or whatever and will take another closer look at the front axles. Maybe one is broken.
