I feel pretty stupid

[mr.black]

I want all of you to remember this is my first jeep. My j4000 has a full time 4wd setup with a handle for low range under my dash. Is this Quadratrac? Would it have screwed anything up if I towed it for about 3 miles around 25mph without taking out the driveshaft? is this a good setup? should I get a different T-Case? PLEASE HELP ME!!!

[BRUTUS]

uh oh... not for certain it is bad but I think it depends on the tcase whether it is locked or will slip. Did you tow it on all fours? or did you have 2 on a dolly?

and check your pm's!

[mr.black]

all 4's

I did

[mr.black]

A buddy has a dana 20 with brand new twin sticks for sale, i'm thi nking about doing it

[KaiserMan]

I see that you list a SOA as a future project. Stock 73's are already SOA front and rear. Has someone swapped in a 74 up spring under front axle and springs?

[mr.black]

yes

[BRUTUS]

There you go... I just replied to your PM but that is cool.

Have you run the J-truck since the tow? I have a feeling you are alright then.

[KaiserMan]

Nice upgrade with the disc brakes and all. You wouldn't have happened to have gotten the original front axle when you bought the truck, would you?

A D20 with a twin stick would be a nice swap, I've never cared for full time 4X4 myself.

[BRUTUS]

I agree with the Kaiser on this one. I am not really a fan of the full time 4x4. Chains should be for timing! Gears are where it's at!

[Stuka]

3-5 miles at 25mph wont hurt it. Longer distance at higher speeds will. An automatic cant be flat towed unless the drive shafts are dropped or the t-case has a neutral (the QT doesnt).

Nothing wrong with chain drive t-cases, so long as the chain only drives the front output. The QT has both outputs driven by the chain.

[KaiserMan]

Stuka's right, there is nothing wrong with the Quadra-Trac. It's a good unit with proper maintenance.

I'm just partial to part time, cast iron, gear driven transfer cases.

[mr.black]

How often should you lubricate the t-case, and do all jeep dealers have access to it?

The 63-73 trucks are SOA, sitting outbound on posts that sit 1/2 way up the frame rails.
They actually sit a bit lower than a 74+ front hanger mount truck.
An SOA on a hanger mount rig gets him the big lift, not off those posts.
It will not matter if he has a swapped in open knuckle axle if it is SOA on the original posts.

[KaiserMan]

Um.... are you talking to me? Cause I'm pretty sure we both know that I'm familiar with post mount rigs and the differences between the 73- and 74+ front suspension.

I'm not asking if someone swapped in an open knuckle front axle. I'm asking if someone swapped in a spring under configured axle and it's appropriate springs and hangers. Which he answered with a yes.

Since I know that all 73 Trucks are (stock) SOA with post mounted springs, I assumed that someone had deposted his truck and swapped in a SU front end, and asked the above quoted question to be certain.

Yes, thats exactly why I have a 1 ton and have to do an SOA on it. It did come factory SOA.

[Tad]

Thomas, no offense intended, I just misunderstood your question/reply.

But now I'm really confused (which happens a lot).

Are you saying you have a front Dana60 (that's what most would consider a front 1 ton axle) and have to do an SOA on it?
Or is it just an 8 lug, spring under front axle that someone installed?
Some pic's would really help.

EDIT:
Never mind, now I see the other post.

Sorry, I put to much attitude into that last post.

An automatic cant be flat towed unless the drive shafts are dropped or the t-case has a neutral (the QT doesnt).
I beg to differ Stuka. I flat-towed my 78 Cherokee Chief almost 200 miles at highway speeds with the QT in N and both driveshafts in without ill effects. There is a N in a 1339 QT; it is not labeled as such on the low range but when you are between high and low range, this is N. The owner's manual even spells this out; you can flat tow with the QT in N and the transmission in park. Even the older cable-shifted low range has a N; I was able to get my J4000 for dirt cheap because the DSPO had pulled the low range cable (he thought it was a choke cable!) and it broke while the QT was between high and low range. When the tranny was put in gear, it went nowhere and made a nice grinding noise going back into park which he thought was because of a bad tranny.

[BRUTUS]

Mr Blue to Mr Black, I just had a thought... if you switch to a D20 tcase, it has a centered output shaft whereas SOME of the qtracks have an offset (to the passenger side) output that corresponds to an offset rear diff. Something to think about before making the D20 jump, as you might experience awkward rear driveshaft angles on your ujoints.

[J4GRAND]

Actually Mr. Blue, the rear diff on a D20 rig is offset to the passenger side too, just not as much as the QT. Several here have used the QT rear with the D20 and vice-versa and had no problems except maybe with gas tank clearance.

How often should you lubricate the t-case, and do all jeep dealers have access to it? The FSM says that the QT fluid should be changed every 30K miles. It only takes 2 1/2 QTS for each change so I usually do it once a year. BJ's Offroad carries the QT fluid or you can make your own homebrewed fluid with 3 QTS 30W NON-DETERGENT motor oil and 8oz of limited slip additive.

I learn something new every day! Thanks J4 :D
