Okay, I checked my notes.
The limited slip was made by ZF and was a rare option for some VW
models. Generally not offered in the US as far as I can tell.
Quotes I got a year or two ago were about $850 used when you could find
them - double the cost of installing a locking diff in a 2wd trans.
I think we are in agreement that which is better depends on what type of
environment you are going to run in.
Limited slip is only going to transfer, at most, 25% power to the other
wheel. Where a locked diff has 100% to both.
The other thing to consider is that since the limited-slip is controlled
by clutches, they will wear out over time and have to be rebuilt.
Limited slip has the advantage of always being "on" where the locker
must be manually controlled. Also, you can't run on dry pavement with
the locking differential unless you want to wear things out in a hurry.
Of course, for the gadget inclined, having an extra knob and light on
the dash with the locking differential would count as a plus.
The consensus of the people I asked, was that a limited slip was a
better option if you felt you were going to hit occasional problems,
mostly in regular driving situations, where a locking differential was a
better choice for extreme weather and road conditions. For example heavy
ice or snow, sand. The Quaife is the best of all worlds, allowing 100%
power and is "always on". It is also the most expensive option. (However
up until last year there was not one available for the Vanagon
transmission. Versions for the type II were around $1,100)
It all depends on what you are going to be doing, and where you are
going to be doing it and how much cash you have to burn.
