The Dana44 in question is the 44a (aluminum), not the regular 44 which is
iron. The two share little in common.

There are strength issues for both available axles (d44a & d35c) and it may
well be a toss-up as to which one is preferable or superior.

I believe that both WJs in question had the factory tow package which comes
standard with the d44a and 3.73 gearing.

The 4 liter engine gets a lot of criticism on some boards in regards to
performance. It is true that it won't win many drag races but is perfectly
adequate for normal operation and towing. When towing in the mountains it
is necessary to lock out overdrive.

On the other hand it had a proven durability of several hundred thousand
miles before a major rebuild is required.

Please note that in my previous post I mentioned the NV249 transfer case.
While it also has its problems I should have said nv247 AWD case.

In any case be sure to get a 'build sheet' from the dealership (or via
e-mail). They offer a wealth of information at no charge.
