The only time I used part time high and low on pavement was when I was testing 4wd on an XJ (selec-trac) and what I did was go into a parking lot and going 5mph or so I shifted to 4hi part time and then full time and back to 2hi and then stopped and went to 4lo. I stayed in a straight line and didn't turn the wheels and didn't exceed about 5-7 mph . There was no convenient dirt around and I was just testing it to be sure it was working ok. I didn't hurt it.

Other than that I NEVER would use 4hi (part time) or 4lo on pavement. Only in heavy snow or off road. I do have selec-trac in my KJ so I use "full-time" for everything elce.

Theres nothing wrong with that at all. Just dont turn and dont use part-time like it was 2wd.

You still where binding even though you never turned the wheels.The F/R diff are not geared the same,they may be labeled the same but they are not.The 8.25 has 3.73 gears and the front diff has 3.72 gears(though labeled 3.73's),just like like my 8.25 has 4.10's and the fronts are 4.09's.Ever actual 4wd vehicle is like this.

I doubt that most realize what you said TJKJ plus the fact that if even air pressure is different in the tires will even make it worse. I never put mine in on blacktop,( why would you???) well unless the blacktop is covered in snow or ice

You may need it in the mall parking lot to climb over that curb and get the front parking space

TJKJ, you are dealing with an expert who is personally invited by Superlift to be a trail boss due to his magnificence. Be it x-fers. tires, or "rev limiters" ( instead of fuel cut-off's). Just stop now while you can still breathe. :lol:

Are you kidding? If there is ANY snow or ice on the ground I put my 4-hi on or the rear end of my KJ is liable to come around to the front - even at low speed. Last winter I ended up doing doughnuts on the road in 2" and less of snow - twice while in 2wd. I was going <30mph both times and 15-20mph the 2nd time it happened. I was just lucky there was no one else in my way when I lost traction.

IME the Liberty in 2wd in just about any snow is very unstable and the back end will easily come around - even if you are being careful.

Yea I know, I was just saying that since he is using it for very short periods of time just to check it then it should be ok.

I wouldnt post a thread like this if I didnt understand it.

Yea, I know. I was not trying to abuse it. I was just checking to make sure it shifted smoothly and for any funny noises and only went a couple of car lengths and I could have walked faster. It was ok and it was purchased and it is fine.

Thanks, Blake.
