Since my axles are toast, what happens if I cut them off at the transmission, remove the end from the knuckle, and flat-tow my Fiero 50-something miles on the highway?  My theory is that the wheels won't fall off, but will turn, and that the transmission won't overheat, and won't leak.

The knuckle or hub end is the critical part.  The end of the axle holds the hub together.  If you have to rent a dolly get one for the rear wheels, too.  Tell them you're towing a Grand Am or other vehicle.  Most won't rent a dolly to tow a Fiero.

Will the wheel fall off, without the axle?

Very possible.

The knuckle is attached to the shock and the tri-links.  The tri-links position the knuckle front-to-rear, side-to-side, and vertically.

Hmmm.  The rear hub fits into that, but would seem to only be held in by the axle nut.

Oh, well.  I can drive it.  As long as I don't get on it hard, the axles probably won't come apart.

We discussed an acceptable method of towing an automatic was to start the engine and put the selector in Drive.  Strap the steering wheel to the 2 armrests.

The nut is torqued at 200 lb.  That holds the hub together.  If you leave the stub end of the CV joint in place and remove the axle from the outboard CV it would keep the hub together.

So, just cut the axle at the CV joints, basically?

Only 200 lb?!!!  Oops.  I torqued them a bit higher.  Well, they stayed tight.

Oh.  If the selector is in Drive, it wojld seem that it would be working the against the braking of the tow vehicle.  My Fiero likes to wander up to 40 MPH, unless I tap the brakes, or start up an incline.

I think that if you cut the axle at the CV, the joint itself will flop around and possible cause some damage.  It would need to be disassembled so that any part of the flexible portion is removed.  To do such would require disconnecting the rear suspension from the cradle and swinging it out as if you were going to replace the axle then bolt it back to the cradle.  This is the only way you could get the axle out of the transmission, and when you do, fluid is going to spill out the seals. 

In this exploded view, you would leave the HOUSING intact and remove everything else.  The nut on the end of the threaded stub compresses the hub against the flat surface of the housing, keeping the proper load on the hub bearings.

I think I could cut it in place, leaving just the ends.

If I could disassemble it here, I could replace the axles here, so no need to move it somewhere else.  I drove it about 300 miles, as is.  Of course, it probably got worse as I drove it.  Another 50 miles should be OK.

If you can do it on a surface road with a lower speed limit would be best.  Of course, with a dolly you could tow it with the rear wheels up.  Just leave the ignition off so the steering is locked.  Take it slow in case you have any play in the steering.  Don't want it to start to whip on you.

I meant I think I'll just drive it.  It drove about 300 miles like this, so another 50 miles, if gently driven, may be OK.

We'll find out tomorrow.

It drove the 56 miles, no problem.

When you replace the axle, consult my hub replacement thread for torque specs.

Well, when it comes to how hard to do things, you can add that any hard is too hard to hit your head on corners.
