Axle Width (Not Track Width)

Kris · #1 07-30-2003, 12:04 PM

Hi all...
Ive been wondering about the width of different axles offered in FSJ's.
Seems like a good thing to know since these axles seem to be popular for swaps into other (smaller) jeeps, as well as sammies, yotas and the like. Not to mention putting WT axles into NT Wagons...

I searched the forums and came up with alot of references to "Track Width" but no measurments of wheel mounting surface to wheel mounting surface (brake to brake).
The track width can differ between two identical axles as rim backspace and rim width can change the track width.

I measured the rear d44 on my 89' and it came out to 58.5". The d35 in my 87' yj is 60.5".
I measured the front d44 some time ago but lost the measurments, I think it was about 59.75.
I measured all of these with 2 straight edges and a tape measure.

So, in the interest of putting together an accurate database of axle widths, would those of you with different models and years of FSJ be willing to grab a friend, measure your axles and post your findings here with the year and model ?

Thanks in advance, and happy measuring...
kris.

Just so folks do not have to look too far, here is the link...

http://www.ttsfabworks.com/tech/WMS.html

...it's just a work in progress.

Kris,
I sure respect your ambition and desire on this adventure, I'll support it the best I can, with as many axles as I can.

I have searched as you have, gotten the same vague info, looked at other web sites, we (as the IFSJA Collective) still do not have this in print, at least not anyplace I can find.

Here are the problems I have found with this search.

A) Track Width, means very little, depends on wheel backspacing and tire/rim size.

B) Where folks measure from. It would be nice if we had WMS to WMS numbers. I believe, some of our members have measured off the rotors in front and not the actual wheel mounting surface.

You have stated all that above (sorry to be redundant), and I'll get some bad responses from members that I have asked these same questions to.

They claim it's "in the archives", it's not, not accuratly, to say the least.

So let's get the ball rolling, straight edges across the wheel mounting surface only. Any axle that can be type and year verified is a winner, others can be just listed as sketchy/nonverified

1970 Wagoneer - Front NT Dana 27 = 59" (stock drum brakes)
1970 Wagoneer - Rear NT 2Piece Dana 44 = 59" (stock drum brakes)
1976 Wagoneer - Front NT Dana 44 = 61" (stock disc brakes)
Later Scout 2 - Rear Dana 44 = 58" (nonverified)

I have 9 more axles I can measure and add over the next 3-4 weeks. 1985 NT Wag (both), 1979 WT Chero (rear), 1972 J2000 (both), Mid 70's J20 (both), Early 70's Commando (front).

Kris, if you'll help keep the ball rolling I'll start pulling down info into a spreadsheet.

We can chop this into verified and nonverified info for clarity.

Thanks,
Tad

Excellent idea.

http://www.jeeptech.com has some of the info that you are looking for.

Try this link:

http://www.jeeptech.com/convaxle/d44f.html

Under each axle type is listed their width (spring pad to spring pad) in typical Jeep applications.

I hope this helps

2ndtimearround,
Not knocking that site but that is some of the very same info that's been posted here before. I seriously question the accuracy of the data on that site, and they openly state that...

"The accuracy of the dimensions is not guaranteed, get out your tape measure".

It was a nice attempt on their part but their grid only contains 2 of the 8 blocks of information they presented, the rest is blank. I don't think spring pad distance is a big deal anyway, they can be easily changed, whereas the WMS can not.

Thanks Tad,
I will have a pair of early 80's (I think 82') j-10 axles here in a week or two.
They are d44f/m20r and I dont know if they are the same as the 82' Cherokee (RB/RBY go check...

)
I will also re-measure my 89's front axle by this weekend.

Any help here is appreciated.
We all have these vehicles so we are the best resource for this info.

Good point Tad!

I have an 81 D44 Front and 89 D44 Rear both setting in the shop now, on the floor. Let me know what you want measured.

Kris · #7 07-31-2003, 04:31 AM

Lawrence...
Measure from the wheel mounting surface, with the brakes installed. This is the surface with the studs.
It is best to do it with two people unless you have a way to clamp a straight edge (I use a 2ft level) to one of the brakes.
Then measure across the axle to another straight edge, dont let the measureing tape hang up on any part of the axle.

When measuring the front, it is best to have the tie-rod installed. If not then try to keep the the hubs pointing straight ahead.

BTW, can you measure in inches...

Thanks for your help.

LOL, you bet Kris, I was looking at that 59.4" thing about a year ago and thinking

This sounds like a very long over due project.
Thanks

I dont want this to get lost...

How many WideTrack and j-truck owners do we have here that own tape measures... ?

BTT

dana 60 from a m1008 is 69"
corp 14 bolt same truck is 67"

mcinfantry · #11 08-03-2003, 05:09 AM

dana 60 front from m715 is 72.5
dana 70 from same is 72

2ndtimearround · #12 08-03-2003, 06:34 AM

Kris:

On the D44 Rear from an 87 GW = 59".

This is wheel mounting surface to wheel mount surface.

The front D44's ball joints are too bad to get an accurate measurment. Sorry.

Kris,
I have a spreadsheet going now.
Is that dana35 a front axle?

Edit: checking how well the spreadsheet will copy and paste into this.

Well, it does not paste very well, seems the UBB code does not accept tabs or columns, it can just get converted later I guess.

I got the Honcho, and I'll pull the wheels and measure tomorrow...

mcinfantry · #15 08-03-2003, 02:54 PM

oops the m1008 is a 1986 ,the dana 60 is a 8 lug
the 14 bolt is the same truck same lug

the m715 is 6lug on 7 1/4

Kris · #16 08-04-2003, 04:55 AM

Thanks everyone...

OK, Im just bumping it back to the top...
And its post 400 for me...

kris.

**River Beast** · #17 08-04-2003, 07:52 AM

Kris,

You actually want me to work on RBY?!?!?! oh my!!! LMAO

I 'll see what I can do....

**Tad** · #18 08-04-2003, 04:11 PM

Just keeping it on the first page, guess we only have 4 members that own a tape.
Thanks,
Tad

Kris · #19 08-08-2003, 07:03 PM

btt...

Yes Todd, get to work...
How's that blender doing ?

OK,
Its a weekend again...
Are we going to get out those measuring tapes, pull off those wheels and get to measuring ?

Hmmm.
You're gonna be working on it anyways, changing the oil and such, how about rotating the tires.
Thats a perfect time to measure the width of those axles...

Have a nice weekend everyone...
kris.

Midnightwagon · #20 08-08-2003, 07:16 PM

uhm soon as i get home ill measure my axles, both old and new. but im sure this lil project will be done by then but ill do it anyways cause i wanna know!!
