Post Part time 4x4

I just bought my jeep about 2 days ago (dont even have the plates yet) and notices that 4 wheel high is only part time 4x4 ... is there any way to make that non-part time ? or is the vast majority of true 4 wheelin' done in 4 low ?

i'm pretty new to true offroading, if you havent figured that out already.

thanks,
Jeff aka Lamah

The only way I can describe it is this way. Part time is the "end user" term for 4wd that shouldn't be used all the time. Part time being not on dry pavement. The Full time 4wd on some Jeeps is for all the time situations. i.e. Foul weather. It seems kind of backwards. But, I suppose that you would be pissed if your wife took the jeep out and said "oh, but it said full time 4wd, so I thought it was ok."

What I lack, my Jeep more than makes up for it.

Well, I have a 96 and it is part time 4x4! Like Bill said its only for conditions that are not dry! Off roading is fine with 4hi you should have no problem! Now if you plan on going through deep thick mud i would go with 4Lo also if you plan on climing Rocks and stuff that would need slow speed and a lot of traction! if you are just cruising down a trail with moderate mud and water then i wouldn't worry about it!

GOOD LUCK

You have the 231 T-case. Like the others said, only use this on slippy surfaces. The case "locks" the front and rear driveshafts together to turn at the same time, so once in a while a tire needs to slip a little bit to not mess up the case. (That's what I was told anyway). 99% of the offroading I do is done in 4lo. The only thing I would see 4hi being used for is sand. HTH

well, you dont need to use 4lo if you plan on going on a two track! In the middle of the woods! you will use more gas and it puts your car under more stress to do so! 4Lo is for hard climbing and thick crap! I wouln't use it if you plan on driving on two track trails and a little bit of mud/water!

Sorry, my bad. I'm used to real offroad trails where we have it in 4lo. Good point about the 2 track trails or whatever, then you could use 4hi, I'm not used to the 231 case.

it doesnt feel like it stays engages thought. it feels like when the rear wheels slip it kicks in ... but maybe thats just cause i'm not used to it. theres a light that comes on and says "Part time" so i was assuming that meant the same as the modern ones which kick in when traction breaks in the rear, otherwise it'd say "4x4". *shrug*

also i noticed 4lo says part time too.

thanks,
Jeff aka Lamah

heh ... ok !#% i got it

part time means you cant use it on dry pavement ... full time has a differential in the transfer case, so it can be left on. i'm clear now. heh

sorry... i was confused.

I know what you mean. I was always aware that there were different 4x4 schemes, and knew that traditional 4x4 is not for pavement, but for a while I figured "part-time" meant that the t-case had some smarts and would engage only "part of the time" as req'd, where as "full-time" meant the tcase was locked into 4wd. It's a matter of convention and jargon.

Oh yeah, and the Honda CRV has "real-time" 4wd, which I guess means that it operates in real time. Cool, I guess I have real-time part time 4wd, real-time full time 4wd, and my girlfriend's car has real-time FWD...

I think I'll go eat a real-time sandwich..

HONDAS SUCK!!!! HAHA I just felt like saying that.. They are not real OFFROAD SUVS! Jeeps are the true offroad machine.

I wasn't saying anything against you CB89XJ, I was saying you dont need to use 4LO on two tracks and light mud or water!

Too bad they don't make a real 4x4. I had an 84 ATC growing up, and it is still going. Now that thing could go off-road.

It's cool man, I honestly totally forgot. I love cruising fire roads and stuff like that, too. I just got done offroading for the weekend when I posted that, so I'm not totally out of the frame of mind yet.
