What are the benefits of manual hubs?
Here is Erik’s two cents: Manual hubs don’t “override” the shift-on-the-fly. When the hubs are locked, it acts the same as before, 2wd or 4wd. When the hubs are unlocked, you only have 2wd of course and you better not try to shift into 4wd while moving (“on the fly”) or you are going to hear some gears grinding! As far as benefits go, when the hubs are unlocked the front axles don’t turn so there is less wear and tear on the CV joints & boots, parts of the differential and also the bearing and bushing in the spindle that supports the outer CV. Fewer unnecessary spinning parts means less friction which gives the slightly better gas mileage. Personally I prefer OEM Toyota (Aisin) manual hubs over Warn. Some members have seen a 1/2 to 1 mpg increase while others say there is no increase in fuel econamy. Why does my T100 ‘s brake warning light in the dash light up in the morning and go on and off for a while on an irregular basis. Member Peak’s report on this topic; This happen to me too,
