LoMax 205 Lowdown

Rebuilding A JB Conversions LoMax 205 T-Case

- Will Morgan

THERE IS LITTLE DEBATE OR DOUBT THAT gear-driven transfer cases have been a popular swap for hardcore wheeling rigs, and often they have been the choice for builders over chain-driven designs for good reason. Of the gear-driven options, the NP205 has been one of the most commonly used cases for serious off-road enthusiasts and builders for multiple reasons, including their sheer strength; the ability to add doublers to cure the inferior, factory 1.96 low range ratio; and there’s twin stick options and plenty of aftermarket support when it comes to finding bearings and seals for repairs or rebuilds. It’s a time-tested case that has proven to be one that can take a beating out on the trail and still hold up through time and, occasionally, neglect.

Our JB Conversions LoMax 205 had begun emitting a growling noise and vibration that was getting progressively worse. Our 205 is fine while under load, has an ORD twin-stick on it that functions properly, and is without issue until we are on the coast-side or remove the load. At that point, the demon within comes to life leaving us to wonder: Will we make it one more mile or will we hear the dreaded “bang” that off-roaders hate and fear most? We figured that instead of waiting until it craters on the trail, it would be smarter to take a proactive approach, get inside, see what’s going on, and fix the problem.
