I have a 98 tracker 2 door.  I'm just making sure that all the 89-98 transfercases are the same.  I would assume so but just thought I'd check to make sure.  Found one with gears and plan on swapping the whole thing. Thanks

No, there are some slight differences, early 89-90 cases have slightly smaller (thinner)
gears, and is why the 4.24 gears do not fit into the case. The real difference is the
front cover, not the body of the case, but you might as well swap the whole case

There is also a version that has a different output spline count, some are 26 and some
are like 12 or 16, and have a square shape to the spline, like an American made spline
on a full size truck

Other than that, the gear ratios are the same, and the cases will interchange, but if
you want the lower gears or don't get the driveshaft from the lower spline count donor
you might have issues later

As wild said, the output shaft spline count changed in 96.  So you will need a tcase from a 96-98 trackick, to be a direct swap for yours.

So if I get both drivelines I should be fine.  thanks

Or swap yokes on the driveshaft, might as well put in some
good new joints too, stay with name brands or OEM

It is just the rear output shaft spline that changed.  All front output shafts are the same.  So you could either get the rear driveshaft, or just the slip yoke portion and put it on your rear driveshaft.

Sweeet thanks everyone
