Good samaritan loses.again

I thought they only had 2 h, 4h, Neutral and 4 low. One lever.

[MT-2500]

That looks like a Blazer
The 94 K 1500 with a 241 transfer case has one shift lever on top but two shift levers from shifter to transfer case.

[laxman21]

That's a k1500 93 p/u.


Never seen a 88 up with the lock on the shifter.


I did find this.

Starting in about 1987, the New Process 231/241 series transfer case became standard in Jeep, Dodge, and Chevrolet applications. These transfer cases are part time 4WD (Shift positions 4HI - 2HI - N - 4L). They have a relatively thin aluminum housing. They are 1:1 direct drive in high range, and use planetary reduction gears for low range with a ratio of 2.72:1 They use chain drive for the front output. The NP241 was typically used in V8 applications.

So is the selector mark differently in the cab? No 4l, N, 2h, 4h?

I do believe laxman is right i miss understood you there are 2 connecting linkages i assumed thats what you meant my shifter looks similar to the one in the photo above. Update! its in the front diff. it will not lock in!!! i mean that i took the actuator out and used a drive extension to push in to lock position i can still turn the yoke(removed the frnt dvrshft) although the axles react they do not lock almost as if a shearpin was broke or something. thats where im at. on saturday night after work

This is just a thought. if i could find a good used front diff. for a reasonable price. would that be less of a headache?all thoughts and suggestions are welcome. when my stuff is broke it really drives me crazy so i am on a mission!

Hard to say.
I would pull the right axel shaft and have a look in there and go from there.

Sorry about that.
You fellows are right.
I was thinking of the older models with the 4W and 4W lock an 4W low and 4W lock shifter setup on floor shift.

the truck has a 3:42 diff. if i can find one under 300 i believe i will go that route. but when i do this i will investigate the one thats in now. i will report my progress as i go. thanks for continuing on help and ideas keepem comin!!

[fmx_guy]

I have found a working salvage diff. for $250 unfortunately i will have to wait till after christmas before i have the time to install the salvage one and investigate the non-working unit. stay tuned!!

I had this same issue, and went through the same fears and diff hunting. When I found one, and started the change out process, I discovered a blown out CV joint. Since it is an open front differential, the broken CV joint was slipping and the other wheel did not pull at all.

[fmx_guy]

thanks for the help i will double check it.havent had the funds to really do anything was laid off for a month.i will post what i find when the weather breaks. thanks again!!!

[fmx_guy]

Ok so its almost been a year. i got the new differential ready to go in this weekend. amazingly its not too bad getting the differential out, didnt even have to take the wheels off!!!! I will report what i find in my old case when i open it.

[Blue Bowtie]

Wow. Just in time for winter. Thanks for following up.

[fmx_guy]

The end of my saga is coming to an end. While installing my new(used) differential i found that the bottom mounting casting had been broken off. My guess is that when the salvage yard pulled this they broke it off and i missed it. so i am making my own bracket. Its in place and is holding oil (no leaks yet) and i will finish my bracket tomorrow. the old differential had pieces of metal falling out when i drained the rest of the oil. i had to remove the axle tube to get it out and as far as i can tell i broke so mething to do with the way the differential locks in. if i can get the cases apart i will try to find what the weak link was.
