Hi i just bought a 1992 LN107 SSR pickup with 3L engine I have manual locking hubs , and a selector lever with H2,H4,N,L4 can anyone tell me how to operate the 4WD ? chamara
Hi garagedoorman well that's what i did, when in L4 , vehicle move foreword very slowly. steering difficult H4 did make driving bit difficult , with speedo jumping erratically. also there was a bit hum , possibly from front diff is there any special sequence ? some say use reverse to engage L4 thanks chamara
H2= high range 2wd, what you would normally drive in with the hubs unlocked for best power and economy H4= high range 4wd, with the hubs locked in you use it for normal driving when road conditions warrant using 4wd L4= low range 4wd, same as above but the gear ratio is lowered so best used for slow speeds and crawling around. The front hubs are manually turned to lock or unlock, unlock and front wheels just freewheel, in lock position front wheels are locked to the axle so they have power to them same as rear end when transfer case lever is in H4 or L4 position. No need to back up to unlock hubs after turning the lever to unlock, only do that with most auto locking hubs, not the manual ones. You should be able to shift from H2 to H4 and back while moving at normal speeds, depressing the clutch makes it shift a bit easier, to shift into or out of L4 you need to either be stopped or moving very slowly as it will grind. Simple system to operate, and plenty tough. Have fun
nook didnt mention some usage quirks. best to not drive it in 4wd on pavement like surfaces, or high traction. this could lead to premature wear or grenading your tcase. there is no differential in the 4wd transfer case, so 1 wheel from both alxes is always turning at the same rate together. if one of the two has a different distance to travel around a corner it will put pressure on the tcase and eventually go boom. dirt,ice type surfaces are ok. harder steering is normal, as is a gear type whine.
Also, when you are turning you will feel it inthe steering wheel, kind of like a tug-tug-tug. Like ShoNuff stated, Do Not operate in 4wd on dry pavement,, bad thinks can happen. And even with just the hubs lock and not in 4wd you will feel it in the steering. Find some grass somewhere, maybe your yard if you have enough room and try it out to get a feel for it.
