Ok.

 

My huge *** 79 chevy SWB was always in FWD mode. Truck ws lifted 8-10" on 40" gumbo monster mudders healthy 350 chevy sm465 trans np 205 T case, ton axles. Spit rear shafts out like a pez dispenser.

 

driving in 4wd on dry pavement with a locked front end is hell. its hard as heck to steer man. and on dry pavement it would definitely screw something up if driven for an extended period of time.

open diff i dont see any problems coming of it on dry pavement with the rear driveshaft out. their is nothing to bind up.

 

First, you've been here since Dec 2012.. You havent been here long enough to see anything.

Second, its not ok to drive in 4hi all the time or recommended to go highway speeds.. HOWEVER, that is only because power is being sent to both axle equally. When turning the front and rear tires dont spin at the same speed, which is the problem with 4hi on pavement. (even though this was explained earlier by someone else) This problem does not exist when the rear axle isnt connected.

 

Actually I was a member on here since dec 09, so you dont know as much as you think. This is a second account. First one got banned for talking badly to a certain ex female mod. Guess its frowned upon to express you opinion in the paid members section. A forum is a place to express your opinion and my opinion is no I would never do it if you have a np 231 t case. Some may see that as the wrong opinion and that is fine bc again this is a forum. Honestly I can care less what others do with there Jeeps bc they are there Jeeps not mine. I'm simply expressing what I would do with my Jeep. But I guess that makes me wrong.

Guess the forum mentality holds true to the more posts you have the"smarter" you are.

 

Your arent wrong to have an opinion, you were wrong to tell him that it would **** up his t case. It's a fact that it won't hurt it, not an opinion.

 

don't mind all this mutter...

short answer is yes, you can drive in 4wd with the rear drive shaft removed.
yes you will leak fluid out the tail stock on the earlier models. (med-large coffee cup duck taped over the tail shaft will help, think XL Timmies).
no you won't leak fluid out if you have a slip yoke eliminator (sye).

i wouldn't be too hard on it in this mode, you can and will twist the front shaft, maybe break the u-joint).

if you have the 242 case, put it in 4hi part time.

 

But that is also your opinion that it won't **** it up. My opinion is that it will. Like I said I don't care what any of you do with your Jeeps but after wheeling Jeeps for past 15 years "I" wouldn't do it. Then again people situations are different and I understand that most people's xj's are there dd's as well as weekend wheelers so you have to do what you have to do I suppose.

 

Anybody who looks at post count to judge how "smart" someone is is a moron. No one cares about post count except people who are apparently intimidated by members who have a higher post count then them, which is stupid as hell. And you can express whatever opinions you want, but when your FACTS are false.. be prepared to get called out on it. Yeah the forum HAS changed, we're alot less tolerant of people who dont know what they're talking about giving people false information. If you're not POSITIVE your right, state an opinion. If you KNOW you're right, state a fact BUT be prepared to get called out on it and corrected if you're wrong.

 

^this guys got 4813 post count! he's a ****ing genius!^ lol jk but yeah. ill take the risk.

btw, could i just measure how much the SYE housing is and then add that length to the tcase then know how much it will stick out so i can measure how long of a driveshaft i need so i would be able to install both SYE and ds all at once? good idea huh?

one more thing. what does it mean when i put my jeep in 4X4 "part-time"? i just don't get the part time...is it cause its now all the time in 4x4? or cause it states that you should only be in 4x4 part time not all the time?

thanks for the help guys

 

Part time is 50/50 power to each axle full time is 40/60 its basically all wheel drive

 

x2, basically how a limited slip works except its front to back axle. You've only got full time if you've got the NP242. Full time lets the front and rear tires spin at different rates, part time does not.

 

Driving without the rear driveshaft was okay for me. I did it for a week or so while I was waiting for my Driveshaft to show up. Just don't beat on it. The front end will fight you a bit on turns the same it would if you are driving on a snowy road in 4wheel. One thing you'll notice is what (if any) vibrations you'll have once install your drive shaft. Even with a SYE, you may need to shim the rear end....

 

i wouldnt do it unless i absolutly had too

 

so part time would be better than full time since in part time all tires are spinning same time, same rate? like a locker would do or am i completely off?
