4.88 gears or not

[LCReunion]

I think that I just thought that it was the 4.88s that was making my truck less great to drive at speed on the highway. Turns out a it is just the LC that ain't so great to drive at 90! In my defense, I have never driven a stock 100 series.



I should have added this above, but if the poster is working in a budget, I would toss the transfer case under drive gears into serious consideration. They should be much less expensive out the door, but won't offer the benefits off road in low range that the 4.88s would. Or that an aftermarket rear locker would. I rarely need my rear locker and I almost never need the front locker. I am doing pretty hard trails too.

SO many factors to how a 100 series(or any vehicle) drives at 80+ on the highway: weight up high or low? suspension appropriate for weight? Tires are a huge thing. Stock LC with Michelin LTX MS tires is about as good as it gets, for a big SUV, on the highway at speed. But a lifted one, fully loaded, with a bunch of weight up high(RTT, etc) and 35in mud terrrains, better have the suspension really dialed in or it suffers. Regarding the transfer case underdrive: go back through this whole thread(and others) and you'll find that it is only a little cheaper(the $505 in the link is for the 80 series, it says there are additional parts needed for 100's and that is what I ran into when I was considering it) in the end, less mechanics are familiar with it, and there is a whine that some are okay with and some are not. It can still be an option. But in the end I really liked being able to refresh my diffs, verify clearances, gaskets, fluids, etc. And no whine.
