Haynes: For problems with your transfercase, either bring to a specialist or tow the entire vehicle to the backyard.

i just needed a couple reference points to prove that "emergency drive" is not 4-low. my jeep acts like it is stuck in 4wd, (no diff) and the jeep was scuffing around in my driveway when i was using it to pull a car out of my garage.

about every five feet of a tight turn one of the tires would seem to backwards like my bronco always did when i had it in 4hi/lo.

my dad replied "take it out of 4 low"

my reply was "i aint got 4lo."

and that lead to a HUGE argument...

[1977cherokeechief]

i know, turn the knob to get it out of emergency drive, BUT, my knob is missing, and i have vacuum leaks galore...

1: make dad crawl under the jeep
2: look at the QT and the Low Range 'hat box' on the rear of it
3: identify your shifters
.....QT is the little vac circle thingy thats tucked up on top with 2 vac lines going to it. A third may or may not go to the vent cap behind it (or the vent cap may have a brass hat.
----LOW RANGE (the steel round big hump bolted on the rear of the qt) has a steel rod going to it (on top, to a steel shifter thats bolted on a shifter bolt) from the lever under the seat. It has 3 positions. Middle is neutral (will free up the driveline in that position). Up on the lever (under the seat) is low and all the way down is normal I believe) With the LOW RANGE in N it wont matter if the QT itself is in E-drive or Normal, the driveshafts will spin free now (or should). Its a nice anti-idiot feature to keep people from joyriding in your jeep.



..put the low range neutral first so you win :thumbsup:

You could act like you saved his life by being ready with a block of wood for a tire... ;)

low range on the left, vacuum shifter on the right, like Ryan says...

[1977cherokeechief]

there is no switch at all in the glove box. i need to get the one out of the j10...


that and my cherokee is the model that does not have the low range, same with the j10.

Well then..you don't have to worry about proving the E-drive is IN lowrange then do you ;)

(I know, you were referring to the E-drive as being low range for you..really what is, is not lower gearing, but a 'lock' of front and rear drivelines without the QT 'slip front to rear') (it's like..a limited slip between the front and rear when power is applied. E-drive 'locks' it 50/50)

Yeah you need to go out and get some vac. tube and re-plumb it and fix the vac leaks..so do I :o I don't think you can tell even with it jacked up if its in e-drive or not without the truck being drivable.

No Low Range? I missed that before... somewhere... Then this thread is just funny! You can probably pick one up for about $50 and you'll be happier with it than without. :cool:

you are probably right, i have only got into a situation where i needed low range once, and i am not stupid enough to do that again...:banghead: once again with my bronco, buried it so deep i could not open the doors....:D still got out, just sat there rocking it back and fourth for about a half hour, until i hit some solid dirt popped it low and wiggled my way out.... only carnage was changing front and rear diff fluids and a motor mount.:cool:


i have heard that the low ranges break easily?:huh:

[Jeepstress]

You heard wrong. You really need to read up on Flint's QT pages. It'll be the best education you can get about a QT. Don't listen to hearsay about these Xcases. Do proper research and ask questions to folks that actually run them - not folks that have heard this and that about them.

[1977cherokeechief]

i will throw up some pics tomorrow of the car i pulled out of the garage... y'all will probably laugh at it though... BUT, i am 6'1" and am really comfortable sitting it it:drivin:

[billyrb]

don't waste your time figuring out what might / might not be wrong with your QT. Just buy the rebuilt one I have for sale (which includes a low-range AND a MM Part time conversion), and send the old one to Flint ;)

MM part time kit:grumble:

the reason i like the QT is the Full time, and the awesome traction they have.

So far in the snow my 1:1 PT kit equipped is just fine.

[1977cherokeechief]

i am not saying that i do not want a pt kit, but, i would rather have the diff in the case...:thumbsup:

[fulsizjeep]

I am sure you are happy with the one speed QT but you are seriously missing out on where you can go without low range. I would consider a single speed QT just a starting point. If you want to stick with the AWD feature of a stock case, start hunting spares to keep it that way or lay down some green for a NOS one before they are all gone. Of course, this is only my opinion. ;)

[billyrb]

Flint, heck, I'll make you a deal on that QT :D

I'll keep my eye out too for low ranges locally, just in case you need spares.

We pretty much shot the holiday budget on the winch. :rolleyes: Actually, you could make me a deal on a chain, seal kit and the coupler in a MM kit. :D Seriously. :cool: The coupler is the part that sits inside the MM replacement differential. Then I will have what I need to build my our own QT similar to the one you have for sale.

We have 7 spare low range units and only one is usable. I have parts to rebuild one as well.




1977cherokeechief - The low range units rarely break. They do suffer a weakness that is really more like a fuse in my opinion. The 10 spline shaft inside wears in the same fashion as the tailshaft on the T400. Once the shaft and sun gear are worn enough, then the slack in the worn spline contribute to wear in other places depending on how heavy your right foot is.

[1977cherokeechief]

i do know that the cherokee is a fairly low mileage one, it has been sitting for at least 14-15 years, then i have the spare case form the j10, which works really good.


i do agree with needing a low range unit for the case, i think that it was kinda stupid for it be an option, esp on a big truck like these...

[fulsizjeep]

Stupid or not it makes it possible to replace the low range without removing the whole case. I seem to recall that the low range option was more expensive than the QT option itself.

There were also some Jeep configurations where there was no room to physically fit a low range on the QT. I think the 6 cylinder Wags and Cherks have the QT further towards the rear and may be one of the configs and the 6 cylinder CJs may be the other. I never had my hands on a 6 cyl Jeep with a QT to verify this.
