The many uses of 4Hi and 4Lo?

I was curious as to when you guys use 4Hi and 4Lo when out in the nature.

Right now I'm watching a mud bogging clip and a lot of these guys spin their tires for most of it (I know I do when I'm stuck in the mud). Do you ever use 4Lo in the mud or just for hill climbing?

if i know i can dig in and get some traction, i will use low range some, but in 2nd gear. if i know traction is a big question, i just leave it in high to keep the tires spinning/cleaned out. just my 2 cents...

ok cool cool. if you're towing someone out (trying to) would it be wise to use 4Lo in 1st gear, knowing you're on a loose surface and under heavy load?

Whats the max top speed for Lo range?? I often drive in 4Lo and 3rd gear when driving on trails. I find it awkward in 4Hi as i often have to slow way down for big bumps/ruts, and if in 4Hi and second gear i often have to slow down even more to shift back to first as I dont wanna bog the engine trying to start in second gear....

Is this a good idea?? transfer case sounds extremely whiny in Low range...

a healthy yota can go in any gear.. as long as your not bouncing off the rev limiter

i normally use 4lo in 2 or 3 on the trail...

but in a mud bog 4hi and then i hit the rev limiter

4 hi and 4 lo

When I am on flat runs or mud runs I run 4 hi or 2 wd. typically dont go too fast anymore to keep from breaking stuff.

In the NW the trails are typicaly vertical dirt/rock climbs, tank traps, off camber rock/root/dirt and other slow BS that you cannot go fastin anyways. So I 4 lo it go slow and gas it as needed typically I am unstoppable. Then again I am locked F/R.

I mostly like 4lo when going down hill I use it to keep slow so I am not standing on the brake pedal all the time. trust 4 lo its a comfy gear up, flat,off camber, and down you can typically keep off the gas and brake when going through a typical trail.

4 lo

unless im on a forest road i run 4 or 2 low(yes i have 2 low with the hubs locked in) its provides much more control. But im with Plumbrbob here in the NW and the trails are tight. Ill even run 2 lo on a forest road if im not going to be on it long

I rarely use 4hi...

if im in the snow while wheeling, i don't need to go faster than what 4 lo will offer me.
Same with every other situation.

I don't really bogg in the mud but ill usually use 4th or 5th gear in lo range.

I always run 4lo on trails. On roads (snow, mud, extremely loose dirt/gravel) I run 4hi.

On my jeep however, I tend to use 4lo quite a bit more as 4hi puts a huge load on the tranny and it tends to get hottt

I use 4HI on pavement in the snow, but I use 4LO off pavement in snow, and in ice, esp if it's on a steep grade.

I use 4LO most of the time for wheeling, and I have to use it to launch boats/jetskis so I don't slip on the ramp, and so I have enough power to make it up the ramp.

For water/mud crossings, I use 4LO.

I also use 4LO for parking on hills since my parking brake doesn't work.

I have always heard that running in 4 low will make the truck run hot after a while, especially here in the south. Any of you experience that?

Mostly because of the higher RPM's would be my guess. It's happened to me before. Mostly only if I'm going up a really steep long hill that I need to keep it revved pretty high(3,000-4,000RPM). By the time I reach the top, I'm ususally getting a little boilover.

When my truck had the V6/MT I only used 4hi in snow on the roads. I could never really imagine using anything but 4lo when off roading without worrying about thrashing the clutch. Now with the diesel and auto, I've only off roaded a few times but I can't imagine using 4lo! The thing is a monster climbing in 4hi.
