Part-Time, Full-Time 4?

[Marlon_JB2]

It's on the New Venture website. The Part Time T-Case can handle a lil more torque than the Full Time T-Case. No arguing that.

Actually it varies the torque split since it has a non-controlled center diff.

True, but those are the official Jeep numbers.

Becareful about that. Some will disagree with you but thats what Ive read on other forums.

I read that here, I thought.. I also thought they said that the part time has the weaker shift mechanism they said as well, using a bearing rather than a shifting fork for the gears. They said the part time is an aluminum case, the full time is a metal case, or cast iron, whatever.

Maybe I got it backwards, but, that's what I thought the other person said...

Wow, this thread took off before i could get back.. LOL

To answer the question a way's back.. Yes, mine is just the Part-Time style. But no big deal, about the only use i plan for it is snow in the winter and mud in the summer, so although Full-Time would be nice in the sense that i don't have to worry about using it on a dry pavement i don't plan on using it there anyway so i should be fine!

And thanks for all the info guys. I figured i would get a better explanation here than the manual can provide. It just tossed me for a loop when i saw that Part/Full explanation and i couldn't figure it out in the vehicle, i haven't seen one with the Part and Full on the lever.

You got it backwards.


The torque split in the 242 in a perfect conditions,meaning driving perfectly straight and all 4 tires aired up exactly the same will have a 48/52.In most cases the torque split is varied due to the center diff needing to spin one side faster the 48/52.Try this little test with a 242 Jeep,remove rear driveshaft,place in fulltime 4wd,try and move,you will not be able to since the torque always follows the path of least resistance,put the 242 in part time and you will move.

JeepJeepster are you telling me that my Command-Trac Part Time 4WD System (as specified on my build sheet) is completely useless during a Chicago snow storm in January?? Do I need to move to a more rural area that still uses the old dirt roads for it to be worth while? April/May rain storms should work.

That is what he is telling you
I live in south Louisiana and my TJ has NEVER seen 4wd high
the KJ has the NP242 T case which has the 4wd part time option
we have only used it when we got in some snow while hiking in the smokey mountains or when the KJ was brand new and had the crappy tires
once we got good tires we did not need it
even when others were slipping and sliding in a mix of ice and rain the following year when we went back to the smokies ,climbing the hills we would hardly spin
if you dont have the NP242 T-case or a shift leaver that has 4wd high
4wd full time N and 4wd low then best not to use it at all on the street

both are about the same
both have the same basic case
both can use the same SYE
the weak link is the internals of the 242

242 is about 15% weaker then the 231.It's a known issue on higher mileage 242's(XJ's) that will not shift out of 4wd anymore from a weak shifting mechanism.

I find it crazy to think that a vehicle that is terrible in rain even with the ESP would be unable to use the 4wd during the winter months on snow covered roads, yet is one of the most popular vehicles on the road. I used the 4wd in my Explorer when the snow was very deep and I didn't have time to do 5-10 mph. Even then I switched back out of 4HI to AUTO. My KJ is heavier than my Explorer was and is all over the road in the rain. If the KJ can't cut it come winter, it will definately be up for sale.

Tires are key,get better tires and you most likely will never even need 4wd in the winter.I drove anywhere I wanted in only 2wd this last winter and never had one issue(now front diff forced me to use 2wd only).I do have sticky tires though and that was the reason I had no troubles.Places where idiots with crappy tires in 4wd could not go I was going right through with my better tires in 2wd with the ARB locked.Not saying 2wd out preforms 4wd in any way but tires has a major role since they are the sole item that is touching the ground.

90% of vehicles roll off the line with crappy tires,that is reality.

The only vehicle that I can think of that comes with good tires is a JK Sahara (nice AT's) and the Rubicon...

I figured after reading post upon post about how crappy the stock tires were, that it could be a tire issue. I know 4wd isn't for daily driving on the pavement. I feel like I'm making more of an issue of this than it really is. I mean, if I am driving to work and there is already 6 or more inches of snow on the ground, I don't see why shifting into 4wheel when I encounter deep lanes or wind rows clogging up the intersections would be bad. Common sense would to be shift back into 2wheel when I can. The biggest issue is going to be finding a good tire for a reasonable price.

Check out Fire Stone Destination AT's or Yokohama Geolander AT's....

Another cheap consumericon996.gif.

A good set of 5 tires will only set you back about $500-$800.

Even a set of Fire Stone Destination AT's is only somewhere around $100 bucks a tire. While they're not extreme off road tires, they'll get every where on road safely, and take you some places off road...

I will have to check out those Destination AT's, planning on buying a new set of tires before winter. My spare is brand new and i will just leave it, yeah i know it won't match but its a brand new spare!

yeah
the JK rubicon comes with great tires
if you can keep them on the rim
I have yet to wheel with some one with a stock JK rubi running less than 20 psi and see them keep all 4 tires on the rims
one will loose a bead

If you want to spend an extra $20 or so on the set, and get something slightly more aggressive, Yokohama Geolander AT's are cool. I'll probably get these next go around.

 

[kb0nly]

Hmm, i know a Yokohama dealer near here too.. I might have to take a road trip!

 

[kb0nly]

Is anyone familiar with the Kumho Road Venture AT KL78??

Nice looking tread on them. I have a local shop that carries Kumho brand tires. I never dealt with them before until i bought my wife's PT Cruiser and it came with a new set of Kumho tires on it. I can say one thing, they perform on snow and ice and thats with the more street stock tread pattern for the car tires. I wonder if these Venture AT's would be worth trying on the Jeep. I'm not a serious off-roader, so for me something just a bit more than average street tire would be nice for the gravel and snow.

 

[JeepJeepster]

Thread is going OT but Ive also got those yoko's and they are pretty good. I dont expect to get more than 30k out of them since they seem to be kinda soft but Ive yet to have any issues with them in rain or snow. I can spin them in the rain if I really want to but thats normal. With the stock tires it was hard to make a turn without sliding over small cars and that doesnt happen anymore.

Believe I paid under $105 per tire from tirerack and $40 for shipping(couple years ago, its went up). Had a buddy put them on for around $35 and called it a day.

Those Firestone Destinations A/T's are good tires too.
