quadratrack versions

[massimiliano]

Hello,i'm from Italy,i don't write a lot but i read ...when i can:D .I am building an xj with quadatrac sj axles but there was a discussion with my friends about quadratrack version;was built only wide track or also narrow track;i have measured my rear axles and it is about 61",there is someone who can help me?Thanks.

QT D44 axles came in both narrow & wide track.

What was the donor vehicle?

Here is some axle information another member has collected.

Make sure you carefully follow the measuring directions at the bottom of the chart. Your current given dimension of 61" is not on the chart.

I got these axles from a friend 3 years ago and he told me they were from a quadrtrack,infact the rear axle has an offset differential to the passenger side,but he can't remember if it was NT or WD;my question was:does exist two version of quadratrac??Because i probaly have a NT and about 61" i have look at the measures a little "quickly"but enought to know it is a NT.Besides i can't measure front axle because is it dismantled.thanks for the cart it is interesting.

The Borg Warner QuadraTrac has same dimensions whether used in Jtruck, WT Cherokee or NT Wagoneer and Cherokee from 73 through 79.

For 80-82, there was a New Process 219 that has left hand front output and centered rear output. It was also called QuadraTrac.

I was talking about the axles mounted on the quadratrack versions,not the tranfer cases,however is the same probably jeep has built both NT and WT cherokee quadra.

OK

There was a variety of right hand differential axles used with the QT rigs. Did you get what you needed then? The chart Tad posted is pretty complete. I have a 76 Cherokee WT that I could measure this weekend.

From 75->79 There is no differance between axles used in Quadratrac vs. Dana-20 FSJ's they were all the same and all offset to the passanger side.

From 75->79 There is no differance between axles used in Quadratrac vs. Dana-20 FSJ's they were all the same and all offset to the passanger side.That is pretty generic. There are narrow track axles and wide track axles, some with slight offset rear for D20 and some with more offset rear for QT. I can say from experience they are not all the same, even if you are just talking about D44s.

(MY ERROR I READ BOOK WRONG !!, SEE NEXT POST BY ME)

For Dana 44 rear axles used in FSJ's for the years 1975 -> 1979 there were 3 different widths, (NT, WT J-10) with two different mounting patterns, (Wag,Cherokee and J-10) but there was no "Quadratrac" offset version, all were offset, and were offset the same irregardless of T-case.
Check the parts books, back your data.

(1974 did have had a Quadratrack offset axles, as did CJ7's)

Funny thing I did notice, the WT and NT Share long side axle shafts, so that would -> WT had less relative offset than NT axles.

[fulsizjeep]

That is interesting bit of info. My data is in experience so I bow to you and your data. I can say this without a doubt: The rear axle of a 74-79 J10 is wider than a 74-79 WT Cherokee.

[mdill]

Ok I had to look closer, and I did mess up reading the book,
Jeep listed out the axles as WHT and WMT after 75 and there IS a differance in the Quadratrac axles (i.e WHT with hydomatic -> Quadratrac after 75, WMT i.e. with manual tranny -> D20 case)
For 74 Jeep listed the axles as With/Without Quadratrac.

My bad.

i have seen that manual/d20 d44 axles have about a 3" offset vs 6" on a bw1339 jeep. but that doesnt really matter, in fact none of this really matters, as long as he has good u-joints it wont care what angle it is. from 1941-1979 all jeep axles where passenger offset, some more than others.

[fulsizjeep]

no problem Mike, I am bad at least once a day :D

[janie]

I am bad at least once a day :D

Krista said it's more like 9 or 10;)

[Lindel]

Krista said it's more like 9 or 10;)


No, just once, ALL day...;)

[fulsizjeep]

No, just once, ALL day...;)yep, that just about sums it up!

[mdill]

OK we are both right/wrong as far as I can tell from the parts book. 74-79 (For 75+)

All J-10 axles Quadratrac, or not are the same
All WT axels Quadratrac, or not are the same
NT axles are different depending on T-case.

NT (Quadratrac T-case), WT and J-10 all share the same left shaft part #812-4034

NT (Non Quadratrac) and WT share the same right side shaft. part# 812-4080 25.24" long

NT (Quadratrac) right side has a unique shaft #812-4084 22.78" long

J-10's right side have either a 30.25 or a 29.25" shaft depending on year.
(76+ is narrower) (?? whatever it is a Jeep :) )

NT (Non quadratrac) left side shaft is a unique #812-4081

That should make it clear as mud :)

Thanks for posting that info Mike. Good stuff.

I had always read that QT J-trucks had a different offset than D20 J-trucks, but every one I had seen had the same offset. So it looks like the different offset for W/T axles is a myth?

J-10's right side have either a 30.25 or a 29.25" shaft depending on year.
(76+ is narrower) (?? whatever it is a Jeep

A couple years ago I was looking for a passenger side rear axle shaft for my '79 J10 with a D20. I think it has a 29.25 shaft, and I had a hard time finding one. It seemed like all that was around measured 30.25.

[Jeepguyp]

knew I was gearing this up.....:D


OK... J-10 trucks STAND ALONE. 1 (wider than SJ) rear 44 only(late 70s). Yes, earlier years had sumthn a bit different.

DONT CONFUSE J TRUCK AND WIDETRACK SJ -- NOT SAME

SJ (wagon, Cherk, and Cherk Cheif) are another animal. my 77 Cherokee Cheif and my 77 Wagoneer have an IDENTICAL rear.

[mdill]

All WT Cherokee axles are the same offset, from the parts books they were designed using parts bin engineering. They were born by mating of
QT and Non-QT NT axels, (QT left and Non-QT right)
All J-10 Axles shared the same left side as the WT Cherokee, but had a longer right side.
So the offset of the WT Cherokee axle is halfway between the QT and Non QT NT axle, the J10 axle has less relitive offset due to the longer right side.
