Anybody have advise on solid axle swap for an 01 4runner ?? We have been told that it may be impossible because of the speed sensors.

 

Anything is possible, and I am sure one of the yota-guru's will chime in after awhile. Good luck and be sure to post some pics of your progress and finished truck.

 

It's not impossible nor is all that difficult if it's planned right. If you lose your front speed sensors all you'll lose is your abs. But in my opinon, you shouldn't be driving with the notion that abs will keep you from an accident. Safe and defensive driving does.

Now, i's too much to go into here and I'm not the best typest in the world so I'm not going to explain how it's done here. Lets just say that your sensors can be added to the front axle's or the rear axle's or there are a number of other ways to get those speed sensors working again, so all is not lost with a SAS. It just depends on how much you want to spend and who you get to do your SAS.

So.... as far as being impossible.. BS.

Now... How big is your wallet

 

Well, thats good to know. The other question I have is that we were also told that the speed sensors control the transmission. Is that true ?

The wallet is lookin pretty thin right now... We are hoping to do the swap sometime at the beginning of 2008. Just kind of want to get some ideas right now. Thanks for the reply

 

youre better off sas'ing a pre 00 or earlier. less electrics to deal with...esp with the multimode tcase. if you want to keep your abs and have a sas as easy as possbile..use an FJ80 abs equipped front axle.

 

i forget the name but somebody on here has a real nice 3rd gen sas. Look for the thread that says somthing about sas ride quality and pm him.

EDIT. i found the name. the guys is SteveO.

 

your problems that you have to deal with

VSC
ABS
and the multimode case

basically just get rid of all of that

go with the inchworm lefty or get a taco chain driven case that has the J shifter and is not pushbutton.

electronics will have to be takin our or relocated if you decide to get a diamond front with fj80 outers and whatever size diff you want since its all custom.

its a pain as I was going to do this with a d44 and just rip out everything in my 01

what are the specs of your 01 right now, are you even locked at all? any crawler setup that you have like inchworms lefty duals or marlin tacbox?

 

I would suggest saving your money and either go with an Fj80 front axle or with a Diamond with FJ80 outers if your concerned with the electronics. Thats the easiest way to get around all that stuff. If your not worried about the electronics, just go with an 85 or later toy axle and have a blast.

As far as the transmission is concerned, I'm not sure how it affects your 4Runner. I know that in my '05 Taco, when I took the speed snesors out the transmission would up shift fine and would kick down if I steped on it, but would not dow shift like it used to when going down a hill. But with the Dual case's in it I'm not worried about that.

 

Better pad that wallet.

I will recomend 80 or diamond. 85 or earlier MT axles are going to require some wheel spacing.

 

and new tcase since its passenger drop and not driver drop.

runnergirl!! really do think this through. do you really need an SAS in the first place?

 

Blake is correct, if using an 80, you would need a new case

For the amount of money getting dumped into a project like this, a new tcase is next to nothing.

Diamonds can come either way.

This swap will be interesting to watch. Please post up pictures and detailed build thread.

 

it is a 3rd gen so she cannot use a 79-85 SFA. The diff on those are PSide and hers on the 3rd gen is DSide

 

she can but just needs a new tcase, most likely is going to have to get an auto to 23 spline case adapter for a geared case.

but the 79-85 axle is going to be too narrow for this 4runner, shed need an fj80 axle or just get a diamond with 80 outers and maybe an 80 ring gear or 8 inch ring gear depending.

where are you at 01rnrgirl?

shoot up an area and im sure ppl would be willing to wrench on that runner.

you know you will be the first 01 to have a "properly" setup SAS if you do it. their was an SASed 01 but it had serious issues as it wasnt done correctly.

edit: saw your area under your name, didnt see that

washington

 

dunno if she is still watching this thread, she may have given up on us

 

SUBSCRIBED: want to see what it takes as I want to do this one day.

 

Thanks for all of the replys. Yes, I still would like to make this happen. It just wont happen as fast as I would like it to. Right now we havent done really much of anything to it. We put the Revtek 3" spacer kit on it, bigger tires and new exhaust. We are hoping to start the SAS process at the beginning of 2008 after the tax refund comes in I will definately post pics of the process My husband is currently working on a 1983 yota pickup and we have to wait til that is done to start on the runner Thanks again

Hey, Neliconcept What kind of lift is on your runner ?

 

01rnrgirl,

I would recommend you do a lot of research. I have a limited which has the Multi-matic transfer case, and an automatic with its own speed sensor, separate from the ABS speed sensors. To date, I still don't have a working speedometer. I currently use my GPS, which is working fine. This has had no ill-effect on my transmission or any other components. Eventually I will get around to getting this fixed. I do have a plug in the tail housing of the transfer case that needs to be investigated as to whether a speed sensor in there will work or not.

As to whether a SAS is done properly, I think this is a relative issue. What I consider proper, others may not, and what others consider proper, I may not. For something to be done proper, I consider safety the primary factor in any project. When doing a large project, such as a SAS (of which some people don't have the fortitude to manage, but will be very ready to criticize others), the safety of yourself and others on the road must be at the top of the list.

I have coached several people in their SAS conversions. I have taken many measurements and passed these on to other people. Why do they look to my 4Runner as the standard? Because the 4Runner works very well. As you may have seen from my videos, I have a very well balanced rig that can travel at highway speeds in comfort, yet crawl the extreme trails. Slapping on some leaf springs is easy, and straight forward. If you keep your rear drums with the ABS sensors, you can tie the front sensors into the rear sensors, and put a Dakota Digital in there to help with the signals, if necessary. If you ditch the rear ABS sensors for a Full Floater setup, as I have done, then you will need to look at another way of generating a signal. As well, you have some other electronics that you will need to contend with. These may play a big part in what you can and can?t do. Research it before you get in to deep with your rig, and there is no going back. As I have stated before, I'm getting around to getting my fixed. Between dirt bike riding in Moab and in town, events and work, it?s a slow process.

Check out TTORA for lots of info on the SAS to get you started.
Check other boards as well for more information cross reference the information, make sure you have a game plan down pat when you start gathering parts. I would recommend you start getting the parts you need and get them prepped. Become familiar with the parts, and when the time comes to cut off the old, you are ready, and will know what you are doing when you put the new parts in.

Here is a little info on my SAS.

I'm not saying my way is THE way, but its A way. There are many different methods out there, so read up and get yourself ready for a lot of exciting work!

 

All I have to say is WOW !!! Your truck is amazing !!! Yes, I still want to SAS my truck I am going to study up and make sure I have my P's and Q's in order Thanks for the reply Now I have something to look forward to !! My husband and I may have some more questions along the way Do you mind if we bug you ? Thanks again

 

im running donahoe extended coilovers on the front and 95 LC 7 wrap coils on the rear, with n86 ome shocks. I also have a 2 inch bodylift. and I will soon be running 315/75r16 toyo mts on 5 stars with omf beadlocks in the near future. I have thought about SASing my truck but the thing is, like SteveO said, you have to figure out a signal with this.

also you can get a speedo sensor from the transfercase to the transmission if you get an aftermarket Geared case with an auto adapter so you can run super low gears (recommended going duals and use the front case with stock gears and the rear case with low gears)

unfortunatly Im going single case super low gears and i havent located a second case for myself just yet.

also if you keep the electronics just get the diamond axle with fj80 outers, thicker housing so you can get the bigger longfields for the 80 series and 80 front diff (with a diamond axle you can place the diff on passenger or driver side drop as its custom)

plan it out, get all the parts you need in stages however, dont do the swap until all parts are accounted for.

You got very knowledgable ppl here and you are in good hands. keep us posted in the research and what you think youll do.

 

Sure thing, and thanks for the kind words.
