I had all my fluids changed at an independant shop, transfer, diffs, transmission, rad flush all synthetic with the correct additives and it was about $450

Whilst at the local dealers (Jim Lupient Isuzu, Minneapolis) for a warranty issue (as yet unresolved diff noise...long story) I had them repack the weel bearings because it was on their fixed menu pricing sheet at $129 which after reading a how to post here sounded like a bargain. They did say when i picked it up that they might have to ammend their menu pricing though

Dealership incidentally have been great to deal with.
