Topic: question for jeffy

[jackhammer]

I was on a different site, 4wd I think, and someone brought up a good and fairly common question.
-
How to identify the difference between D35 and D44 axles.
-
On the 3 or 4 forums that I frequent or the other 2 or 3 that I am just a guest you are very quick and fairly opened minded when it comes to people having there own opinions about what would work for there set up, so there for you came to mind.
-
I know this is a dedicated 4bang site but axles and gearing means just as much to us little guys, if not more.
-
Using your knowledge of different axles, what they could be found in past years-possible gearing, bolt patterns, swapability(I love making up words), ID tags and pics for the impaired(like me), and if they have disc or drum set ups.  I would lean towards an axle that was easy to swap with decent gearing and disc  rear brakes just b/c I love rear discs(easier to maintenance)
-
Just an idea, I know your probebly swamped but this would help this site since I can not find this info posted in a tech page on any other site and its almost as common as tire size question. Thanks for your time

Well, under the FAQ, there is second on the D35.  I haven't done a axle ID in a while and not for this forum.  Gearing has been covered in the FAQ also.

I guess I could dig up an Axle ID chart someplace.

Here is a great site for axle ID. - - - - - -

great site....decent prices on body parts too...can anyone describe the whole toyota rear end thing

[Jeffy]

What about them?

[jackhammer]

Next spring(snow plow cash permitting)I want to get at least 4.10/4.11 going on. I am tossing around a couple different ideas.  But with every upgrade I am planning if I can get 2upgrades for one it catches my intereast a bit more.  Swapping axles will be one upgrade while if they come with rear disc brakes would be a convenient 2nd upgrade in one.

-We had talked before about this and you recommended the swap from a manual TJ would give me the gearing desired to help push 31s or 32s and help relieve stress on the auto trans(this spring I am going to run oversized extra trans cooler w/fan and I am going to add a trans temp gauge. Hoping this will prolong the life of my current trans at least till I am forced to rebuild)

So is this toyota rear end a new wave thing or just not talked about B/C of the Jap label. Is it an easy swap,Disc brakes,Ratios?

[Jeffy]

I beleive there is a brief article un How-to.  It's nothing new.  Just most new Jeepers don't know about it and only want a 8.8".

[jackhammer]

Well it looks like the Toyota is not really for me.  What would give me at least 4.10/4.11 with rear disc brakes.

[Jeffy]

Well, you can put disc brakes on just about anything.  I forget if you have a TJ or YJ.  If it's a TJ, then the simplist thing would be a Rubicon 44 with 4.10's.  Other then that a Ford 8.8".  But you'll need to buy a bracket set of them and beaf up the housing.  (ie. you need a welder.)

In most other cases you'll have to swap in gears and add disc brakes but then the housings are sometimes cheaper.

[jackhammer]

Most disc brake kits run around 400.  I have a yj.  was it you that said a 4cyl manual is geared 4.10/4.11.  I heard 95 and up 8.8 out of explorer has rear disc.  What are the gear like and while they work with my current front end so Maybe I could do rear axle swap one year and front the next.

[Jeffy]

Yes, 2.5L Manuals have 4.10/4.11 gears stock.  And yes, '95 and up Explorers have rear discs.  But only the Limited V8 Explorers had 4.10 gears.  You'll still need regear the front though.  One problem with teh 8.8" is locks you into 5 on 4.5" bolt pattern (stock bolt pattern.)  So if you wanted to upgrade the front to a Dana 44 with 6 on 5.5" pattern, you'd be forced to use spacers that convert the bolt pattern.  (Not that good.)

So you'll want to make plans for the future now before you get locked into something.

[SMC4WD]

Yes, 2.5L Manuals have 4.10/4.11 gears stock.

Automatic transmissions have a different gear ratio?  They made a 4cyl. with an automatic??

Are we talking about a YJ or a TJ?  I have a YJ and bolted up a 9" with disc brakes for pretty cheap.  Check junkyards for a Lincoln Continental or Mercury Marquis (early 70's models).  With a YJ it's as simple as welding on spring pads.  It's 28 spline, so a few companies make lockers, or step up to 31 splines and have the axles dripped for a dual bolt pattern.

[Jeffy]

Well, first off, I claimed Jessica, get your own girl!  :twisted:    :wink:

Yes, auto's use different gears because they do not have a OD.  This goes for CJ's, YJ's, XJ's, MJ's, KJ's and TJ's.

Those 9" are of the smaller variety I believe, 28 spline.  I think they're also small bearings.  You can upgrade to 31 or 35 spline and truss up the housing though.  Not sure about the bearings.  You could get a 31 spline diff from a truck and have the axleshafts cut down and resplined.  I'm not sure if the flanges are large enough to accept a dual pattern.

[SMC4WD]

The axle flanges are large enough(I've done it).  The only bigger bearing needed should be the 'set10' bearings at the wheel side of the tube.  I would hope that anyone doing a gear change and especially a diff change, gets new carrier bearings (and pinion bearings if doing a gear change).

Up'ing to 35 spline axles require the same bearing upgrades.  ARB has a 40 spline 9" locker, but that requires an entirely new third member.

I'll talk to later about Jessica...
