First off I have a samurai , should be about the same though , Im not sure ... The directions werent great but if you dont get in a hurry, and look over something ,its pretty easy ... I put mine together with one gear backwards so I didnt have 2 hi or 4 high only 4 low , I thought it was the shifting , I took it apart again put it back together, and it still didnt work ... so I thought either I done something wrong or they forgot to send me something , anyway I tore it back apart and looked at every little thing I put on , and it was so obvious that the gear was upside down ... I felt like and idiot ...
Anyway the most complicated part , I think was the shifting rods , they are held in by spings a a steel ball be careful , when removing the rods the balls could fly out . I went to the suzuki dealership to get the rear seal for the t-case and they guy there gave me a digram of all the parts inthe transfer case and it showed me where those steel balls went .. I was glad even though I had already figured it out . it gave me peice of mind ... I did lose one of the balls flew across my car port and bounced a few times , took 2 Hrs. to find it ...
Mine is a Calmin it makes no noise and I have more power now than I did before I got the big tires. made a big differance ... I had a friend that got one of those T cases with the 2 low and we went out rockcrawling one day and he couldnt get it to go into 4 low and he tried for about 30 minutes . come to find out they have a diff shift pattern than the regular one , and he didnt know it was diff ... thats the only trouble he had , and it was all in the shift pattern .
If you need anything let me know and Ill help as much as I can ..
