Hey LC Fam!
I have a headscratcher going on. The 88 FJ62 I bought about a month ago is going through some mechanical rehab. A lot, as it turns out. I have some conflicting mechanical parts on the rig, or so I think, related to the transfer case / front diff engagement of "H4". What drew my attention to this "headscratcher" is that the "4WD" dash light stays on all the time. Here are he facts. The dash has a "H4" switch, which is meant to transition the rig from H2 to H4. My original 88 owners manual explains this clearly. The owners manual also illustrates that the manual transfer case shifter has three positions. "H2" - "N" - "L4". see picture attached. Here is the twist. The knob on my transfer case shifter has 4 positions. "H2 - "H4" - "N" -"L4", see picture attached. As far as I can tell, the shift lever allows for all 4 positions. Finally, the rig has manually locking "Free-Wheeling" hubs as I assumed all FJ60 and FJ62's have. The locking hubs are "new-ish", which the previous owner told me he had replaced.
What am I missing? Why the redundancy of the "H4" switch, and the manual "H4" shifting? The local Toyota service manager suggested that this model had an option of Auto-Locking Hubs, and that someone had replaced these with manual locking hubs at some point, which does not sound right to me. I have never seen an FJ62 without manually locking hubs. My owners manual does not reference this as an option, and I have not been able to find anything online that points to auto locking hubs ever existed on an FJ62. What the what!!?? Any ideas???
