I don't know why it hasn't been mentioned, that I have seen, but there is a
cure for most of the "I'm stuck" issues.

Turn around and back up!. One has a lot better traction pushing than
pulling. Taking my coach skiing, I have been substantially more successful
in moving around ice and snow backing out of places than going forward with
chains.

I once broke a rear axle in a '45 Ford flatfender and the only way off the
beach in soft sand was...backward.

Try it. Most of the time it will work for you.

Helps in snow. Very little on wet grass. Once you spin it's mud and you dig yourself a big rut.

Can conform. The LSD is worth it
Best example was climbing a steep, winding, slippery campground road in the pouring rain, I could feel one side slip then the other, back and forth and the coach just walked up the hill, it would have been a trick in a one wheel wonder

TG,

I can answer that pretty clearly. There were two very good reasons:
1 - The LS part that JimK uses was not available, and the other lockers have a real bad time on the front. (My father proved this wit a 68 Wagoneer.)

2 - The traction available with the bias ply tires of the day would have made it a moot point.

And the added cost for something that should not have been needed (in their view) was not justified.

I can also vouch for the limited slip final drive. It has saved my bacon on numerous occasions. Just as Keith stated, it will tend to 'walk' up a
steep gravel hill. It feels weird to feel one wheel getting traction, then the other, and so on, but it keeps you moving.

I have also had mine pull me through a mudhole once when I took a wrong turn on the way to a forest service campground near Williams in Northern
Arizona. Without the L.S.D. I would have surely been stuck in the mud on THAT one.

We have spent thousands trying to see which co would do a LS for us since
1998.
Big problem was the Narrow housing .
We reached out to several in USA and overseas.
Shipped drawings and housings and the. Bottom line was always a NO.
Few years ago a guy reached out to us with a unit and we tried it and
started ordering them, but when a supplier that requested money up front
would not return calls or emails for over a month, I felt he had some
issues that was too risky to continue . I have been burned by people that
wanted money up front and never delivered or died.
So now we have taken that original unit and Mfg them here.
Limited Slip is not a positraction , so it does work well on the front.
After around 250-300 ft lbs of torque difference, it will slip.
There is one large pinon bearing that is very high priced and hard to
source so it is costing over$ 160 for it.

GM does not put posi in front drive vehicles because when both wheels spin you lose all steering control. Kind of a big deal.

John,
That is why ours is a Limited Slip and works on our front.
