4X4 How to shift

Hello,

So winter is upon us in Minnesota and I thought it would be best to make sure i'm shifting into 4X4 correctly. I have driven 4X4 trucks with auto trans and manual trans cars before, but never 4X4 with the manual trans.

My main question is....... any special rules for shifting on the fly to 4x4HI with the manual trans?

**2012 Jeep Wrangler Sport**

-Clutch need to be in or out?
-Okay to shift into 4X4HI if your in moving while in neutral?
-Any times or gears when you would not want to shift to 4x4HI (I know my Ranger was under 45 MPH per the owners book.)

Example - I have this hill on my way home from work that I always drift up in netural to a stop sign...well tonight i realized half way up the hill that it was snow/ice covered and would want to be in 4X4 to get moving again. So I pulled it into neutral then shifted into first once i stopped at the stop sign and then drove off. Is that okay??

Any tips/advice would be greatly appreciated.

Also, not worried about 4X4LO...dont plan to use it...figure if it require 4X4LO i'm probably going to crash

You are supposed to be able to shift from 2 to 4HI and back at any speed up to 55 mph, but I don't like shifting from 2 to 4 while moving. Personal thing I guess. I just worry that I will miss 4HI and end up in 4LO causing problems. A few times I have missed 4HI and ended up with the transfer case in neutral. You can be in gear, just push the clutch in and pop the transfer case into 4HI. Easy peasy.

You can shift on the fly from 2 to 4 and back again as long as wheels are not spinning with or without using the clutch. If you are in 2wd and spinning, the two drive shafts are then rotating at different speeds, so that could be a problem. With the JK; the front drive shaft and axle are rotating all the time the vehicle is moving. So, if you aren't spinning the rears, the front and rear would be rotating at very close to the same speed so the gears would automatically mesh when you shift. Hope this helps you out.

Sounds like you did fine. I think you're ok as long as you don't hear any grinding.

Seriously though, I try to shift into 4 HI before I need it, and I do it going fairly slowly, myself. I just push in the clutch and shift it into 4 HI, as long as the clutch is in you don't need to be in neutral.

For 4 low, I shift it while rolling between 1 and 5 mph, which keeps it from grinding, which it seems to like to do if stopped completely.

I laughed at this:

because you will be missing most of the fun to be had in a Wrangler if you never go into 4 LO. Just sayin'.

Remember, when you are in 4wd, hi or lo, your turning radius increases and you may hear and feel the Jeep trying to fight your steering inputs. This is normal, you just need to adjust your driving/turning when in 4wd. It's a Jeep, not a sports car.

Welcome to the forum, and don't forget to wave!

Personally every vehicle I have owned has been manual trans 4x4... I live in Florida so the 4wheel drive is essential when going off road ... I always stop or almost before I go to lo or high range... And if there's a Any chance I'm gonna need 4x4 in any circumstance I lock it in before hand...

Clutch in or out, below 55, dont do when spinning the rear. Sounds good, thanks for the advice. Looks like I will need to use the 4x4 for sometime given the wonderful plowing that was completed in the twin cities. Thinking mud flaps for the winter months.....snow really kicks up off the front tires
