Exclamation 4 LO how bad did i screw up my jeep and what am i doing wrong?

ok well i have a 2011 mojave unlimited love it and never have had a problem before besides a few minor thing but it seems like im being hit with a wave of things at once to start if a small leak and a annoying noise while going over bump, but my biggest worry is my 4x4 right now ive never had to go into low before so i havent noticed till now 4 high has worked fine but today i tried to go into low today and this is the way i did it (started in 2h went into 4h fine slowed down to about 20km put the regular transmision into N and then the 4x4 shifter into N and slowed down to about 5km) then i tried to go into Lo but it made a grinding noise! and the i tried to go back into high and did the same! what am i doing wrong!? and then again on my home and tried again and did similar things and the only way i could recover is by being in park but even then sometimes that doesnt work some pls help, and how badly is the girding? i was holding it there but it did happen a number of times trying to go?

Don't stop in neutral. Just move it to 4L in one smooth motion, and when you're done move it in one motion back to 4H. The slow rolling should help, but it's still going to make noise. Just don't force the shifter. It's probably not messed up. Or if it is, it's not because of what you did.

Go very slow, 1 mph or less works best for me... don't leave the T-case in N long, just shift through it. Everything else you did sounds good. You more then likely didn't hurt anything, I just wouldn't make a habit out of grinding, and if it does grind let off the stick, don't try to push through it.

its a tougher shift then 2H to 4H b/c your changing the output ratio, 2H to 4H just engages the front drive shaft.

Holy crap! No don't jam anything. Read your manual. You should be barely rolling. As you are moving pull it nack into 4L, just let the gears "take" it in. Smooth steady pressure and when the gears line up it slides right in.

Smooth and quick, don't stop in N.

4H to 4L or 4L to 4H
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift
an automatic transmission into NEUTRAL (N), or press
the clutch pedal on a manual transmission. While the
vehicle is coasting at 2 to 3 mph (3 to 5 km/h), shift the
transfer case lever firmly to the desired position. Do not
pause with the transfer case in N (Neutral).
NOTE:
Shifting into or out of 4L is possible with the
vehicle completely stopped; however, difficulty may occur
due to the mating teeth not being properly aligned.
Several attempts may be required for clutch teeth alignment
and shift completion to occur. The preferred
method is with the vehicle rolling at 2 to 3 mph (3 to
5 km/h). Avoid attempting to engage or disengage 4L
with the vehicle moving faster than 2 to 3 mph (3 to

5 km/h).

If at a complete standstill and it doesnt want to go in, I let the clutch out a little with it in gear to spin the input shaft then try again. In the auto, yes, pop into drive then back into neutral.

This is a pain on sand, I go back & forth from N to D until it slips easily into 4L.

First few times I ground (grinded?) the gears and haven't done that all summer. Must need to grind/wear the gear edges down a bit at first.

The idea is to be in 4L before you need it.

Well said. I always try to anticipate the need and be ready before I need it.
