That's not entirely true with Jeep 4-wheel systems. NV231 (Command Trac) only has 4-hi part time, which is no good for pavement (2004 Liberty most likely has). There is the NV242 (Select Trac) which has part time, and full-time 4-hi .. Full-time 4-HI was designed for pavement 4x4 all-time.

Personally I think the labour charge seems high, but if they were draining your t-case and noticed excessive metal flakes (could be from high 4x4 usage). They decided to crack it open, along with both front and rear diffs to check for mechanical issues. Just speculation, but I know personally jeep 4-wheel systems can be troublesome (PS: I love my jeep quadratrac system in the snow! )
