Help Need a Dana 60 with ABS for an FJ Cruiser

I am trying to do some research on finding a late model Dana 60 with ABS. My query is to find out the tooth count, operarting range in volts(???) and wave pattern of several models to try and match one up with an FJ Cruiser to have the ABS still work.

I know it is a rediculas thing to do but there are several systems that monitor what the ABS is doing to make the vehicle run properly and the Active Traction Control is a great system. I know there are those out there who would say forget it and just lock it up and put in filters to buffer the signal to the computers but I would prefer to do the research and find a solution.

Nay sayers out there for sure but understand this is still going to be a daily driver for a while and I think this can be done. All I want is a strong solid front axle with ABS that will work with the FJ Cruiser.

Is that too much to ask??? I tried to search several forums but didnt find the info. If anyone could help me or point me in the right direction I would appreciate it.

You try a superduty?? The ABS is in the brakes..

 

[Isotel]

sounds like a cool idea, i dont think its been done, but try the 4runner forums..
What about using an FJ80 Axle w/abs.. Either figure out a way to flip the housing, or have a custom one built..

Or just put an ARB in it! lol

What sized tires are you planning on running??

Yeah I haven't thought of running an 80 axle, that might be the easiest way to go. I can retube the 80 housing and cut axles for it so that is no problem. Thanks for the input

Probably going to run 35s or 37s.

Is ABS that effective when running 35-37 mud or all terain tires?

Not sure I follow, does the vehicle know what size tires are on it. or is it simply monitoring how many teeth it sees?

I would tend to think that the ABS system doesnt care what size the tires are. I know there is a difference between the tire sizes and that affects the sensors reading to the computer but the end result is the same. The sensor still gives feedback to the ABS control module!! This being the case I do believe that the system would still be effective running 35s or 37s.

I would look into the fj80 axle and then maybe run a mini truck doubler to get the correct drop side.

If you run a d60 in the front with 35s or 37s you are going to have about 4" of diff clearance.

 

[Mace]

so how much lower is a D60 compared to a 80 series axle??

 

[Tim Scully]

Guys there has to be someone out there who has some information on ABS sensors and volt ranges for a late model d60 or an 80 series axle

Anybody????

I have a 2002 D60 sitting in my garage. the ABS sensors look like any other Ive ever seen. I'm not sure what the teeth count is but I pretty sure that voltage doesn't matter (teeth count either since it is either reading movement or not and teeth count should be fairly close) since the computer provides the voltage & the sensor just acts like a switch (on the superdutys anyways).

You might be able to get the info you need on thedieselstop.com forums, but That information is not something that is general knowledge on any forum and probably only contained in factory manuals. The rear Sterling that goes with my front axle has a single ABS ring on the ring gear with 120 teeth if that helps at all.

If I was going to do it over again I would have gone with an early model 60 with kingpins. the new axles have balljoints which make a reliable highsteer nearly impossible, as well as unit bearings which make 35 spline outers very difficult and are inherantly weak and cost about $250 each to replace.

Also don't forget that the calipers are HUGE and will need large amounts of fluid that your ABS system & master cylinder are not designed to deliver. As far as ABS not caring about tire size you are correct, but with that large of tires you will have a hell of time getting those things to lock anyways with stock brake componants. 80 series stuff MIGHT work but I don't think that Toyota keeps anything compatible for 5 years, let alone 10 (especially ECM's, ABS controllers, sensors & other computer related items etc..)

I know you don't want to hear it but you'd be better off scrapping the ABS & traction control & completely re-doing your braking system to handle the large axles. Atleast you'd end up with something better than a balljoint 60.

After a little thinking you could probably use a Superduty master (they come with an ABS sensor, but I'm not sure how it works) & re-plumb it into your ABS controller. This would give you the required volume & then all you would need to do would be to check the tooth count of the 60 compare to what you have stock. Then you would need some device to convert the pulses to match what your ABS would like to see (to probably match your VSS) or you could modify a unit hub bearing to have the same tooth count as you have stock.

You need to get ahold of both factory manuals & hope they have detail info on the systems.

...would still be effective running 35s or 37s.

35's or 37's and a Dana 60??? You are kidding right? Three inches of ground clearance under the front diff does not sound appealing…No reason at all for a 60 front axle if you are only going to run 35's or 37's....

I know it is a rediculas thing to do...

Probably why you are not finding a lot of info on it....



Most folks running big axles are not even concerned with a speedometer, let alone ABS.


Get a custom front housing made, or go with a Marlin set up and run an 80 axle with Chromo inners and Longs, and call it good...

ABS stuff and quality axle pieces all in one.



Good luck!

Dude, I'm going to jump on the band wagon with everyone else....there is no sense in putting that much weight and loosing that much clearance just for 35's or 37's

After it is all said and done you could prob. put a set of 'Mog's under it for what you'll have in a set of 60's BUT WITH MUCH BETTER CLEARANCE!

 

[Tim Scully]

Im going to run RockCrusher housings on the 60 so Ill probably have about the same amount of clearance as an 80 axle. I haven't measured it but the Rockcrusher housing has a good bit more clearance than a traditional 60 housing.

The point isn't ground clearance. I am looking for an answer to the original question!! Is there anyone out there with experience with 80 series ABS or Late model Ford d60 with ABS?????

I appreciate the responses and understand what all of you are saying. I am trying to find this out for a rig I am probably going to build. I have a buggy with unimog portal outer and a 9" center sections. I have another dedicated trail vehicle with d60s. I get it.

How about some help!!!

every search I did showed people specifically looking for non-ABS axles....hhhmmm

The problem with the FJ cruiser ABS/A-TRAC system is that it uses a very special, high tech wheel speed sensor. Its called a magnetic resistance element speed sensor and does not have a traditional "toothed" pick up wheel. The wheel bearing actually has a number of north and south poled magnets built into it and that is what the sensor picks up. This is why the FJ's active trac works so well. An MRE type sensor can pick up wheel speed at about 1/10th of a mile per hour, while a traditional inductive pick-up type wheel speed sensor needs about 3-5 miles per hour before it even knows the wheel is turning. Additionally the MRE sensor can determine direction of roatation (forwards or backwards) which an inductive pick up cannot determine. To my knowledge Toyota is the only manufacturer that uses an MRE type wheel speed sensor. So I doubt you will find something in the boneyard from another manufacturer that has the same type sensors.

This is also very new technology and has only been around since 2003, so an 80 series axle will not work either.

So aside from something totally custom and very expensive, I think your out of luck.

 

[onesprung60]

One more thing worth mentioning, the MRE sensors output is a digital signal (think squarewave) while the inductive type is analog. Two totally different type of signals.

I am not saying it cannot be done, anything can be done with enough time and money. But it will be difficult to do properly, and a Toyota computer is not easy to "fool" into working properly.

I wish you the best, and would like to see you accomplish this.

I spent a little time looking through some Dodge FSMs.

Apparently the techs do not need to know pulses per revolution or pulses per minute at a given speed. The WSS measures pulses or it does not. Techs don't have to diagnose problems dealing with the number of pulses. They check presence or absence of signal, not the frequency. They are given specs for resistance in the wss and air gap between the wss and the tone wheel.

The scan tool doesn't tell you pulses either. It tells you mph/kph. If you change tire sizes you don't figure the number of pulses, you input tire size.

Toyota has less info available to the techs.

Ford is always very tight with info like that as well.


So nobody is being rude. It's just not a commonly needed spec.

 

[Tim Scully]

I wasnt trying to say anybody was being rude Gumby. I really understand where everyone is coming from, the simplest thing to do is to go for bypassing the ABS all together. The GC wasnt the point though.

I appreciate the input. Onesprung, the sensor difference is probably going to be a deal breaker due to the way the sensors work. I guess short of making that type of bearing assembly for a d60 it wont work. That would be really expensive. Oh well that is what research is for.

Didn't the Ultimate FJC retain the FJC hubs to keep ABS functionality with a Dynatrac D60? Check with All Pro or Dynatrac and good luck. That's the way all FJCs should be--2 solid axles!
