Toyota Solid 8" Axles

[brimy311]

Figured we needed some toyota axle info :)

Axle Id


Toyota 4x4 Front solid axles
-6 lug 6 on 5.5"
-8" ring gear
-Removable center section(3rd member)
-30 Spline front shafts, they neck down to 27 spline into the birfields
-birfields, basically an early version of a CV shaft. Designed not to bind like Ujionts do when driving in 4x4.

-Trunion/Kingpin/Knuckle, no ball joints.

-Stock Aisin Locking hubs are very stout, usually only replaced for drive flanges.


Toyota 4x4 Rear Solid Axles
-6 lug 6 on 5.5"
-8" ring gear
-Removable center section(3rd member)
-30 Spline axle shafts
-86'-93' Toyota rear axles are beefier and wider then 79'-85' toyota rear axles


Stock Toyota front axle measurements for comparison:
55.5" wide, 29" spring perch centers, '79-85 Toyota trucks and 4runners, SA Hubs
58.25" wide, 29" spring perch centers, '79-85 Toyota trucks and 4runners, IFS Hubs
63.5" wide, (set up for coil springs) 90-97 FJ80 and FZJ80 Landcruisers
'86-95 IFS front end is about 58.5" wide
'93-98 T100 IFS front end is about 65" wide

Toyota Rear Axle Widths:
55" wide, '79-85 4wd trucks/4runners - 6 Lug
58" wide, '86-95 4wd trucks/4runners - 6 Lug
56" wide, '79-95 2wd Trucks - 5 Lug
60.75" wide, '95.5-up Tacomas/4runners
66.75" wide, '93-98 T100 trucks

Toyota aftermarket upgrades:

www.toyotasuperaxles.com

Chromoly 30 spline super birfields and axle shafts.


They eliminate the neck down on the shaft as well


www.marlincrawler.com

Billet Hi steer arms


Or Forged Steering arms


Factory Electric locker and Hi pinion diff:

Offered on landcruisers (fj80) are Front Hi pinion diffs


Also available is the toyota Hi pinion Electric locker


Standard Low pinion Electric lockers were available with the TRD options on Tacoma's and 4runners.

Vented rotor swap

Solid toyota front axles come with solid (unvented) rotors

By buying rotors from '81 and up Toyota LC FJ40 and fj80


and calipers from an IFS Toyota (86+ P-up or 4Runner).


You can swap to vented rotors. Does not add any width to the axle.

Rear Disc brakes

Rear disc's are pretty straight forward on toyota rear axles.

http://www.sky-manufacturing.com/
These guys sell caliper brackets that bolt on



or you can build your own

Many ppl have done them diffrently using different parts, but most us chevy 1/2 ton front rotors and calipers from chevy S10 or if you want an ebrake Cadillac Eldorado.

I know this post is old but were would a good place be to find Toy front and rear solid axles? PLaying with the idea of putting them under my ZJ.

[Haggar]

They are a bit narrow for a ZJ.

ZJ axles are about 60" WMS/WMS, Toy fronta are 56", the rears are 55" although later one sare 58.5"

If you really want a Toy axle, the late model 4 runners were 60" wide. You could put spacers on the front to get it to 59- 60" or so. My currnet front is 59" with spacers, but I've got a 62" wide custom built housing thats going under it.

Whats the difference between 4 cyl rear third and 6 cyl rear third?

All pre-'95 4-cylinder 4wd mini-trucks & 4Runners use the Toyota 8" 2-pinion differential front and rear (except turbo models). This is known as the "4cyl diff." This diff is by far the most common diff in older Toyotas.
Ten 10mm ring gear bolts, 27 spline pinion shaft.


4cyl Turbo and V6* 4Runners and mini-trucks use the Toyota 8" 4-pinion differential in the rear. This diff is known as the "V6/Turbo diff." It has larger carrier bearings, is generally stronger than the standard 4cyl version, and is a direct swap into axles that use the 4cyl 8" diff. Separate gear sets are made for the V6 style diff (only from Toyota and Precision Gear), but cheaper, more readily available 4cyl style gears are commonly made to fit- the only difference being a very slightly larger pinion gear on the V6 style gear (the actual strength difference in gear sets is debatable). The strength increase in this diff over the 4cyl diff comes mainly from the beefed up housing, which stiffens the entire assembly, keeping the gears in proper (stronger) alignment.
Although somewhat rare, there is a version of this diff that came from the factory with 4.88 gears. The carrier (3rd member housing) has a different pinion offset so that the ring gear doesn't need to be as thick. This means that no gears other than the factory 4.88's will fit this particular diff. However, diff cases, commonly called carriers (factory, LSD, lockers, etc.), for the standard V6/Turbo diff should be interchangeable (4cyl and V6/Turbo carriers are NOT interchangeable).

How hard would it be to put toy axles under my TJ....would it be cheaper/e-z-er then other opions

Talk to Nyxis, he has them. They are narrower than TJ axles, wrong side diff, wrong wheel pattern, leaf spring, etc...

Actually not even close lol. It is a TJ tub on a YJ frame with an entire Toyota driveline.

[brimy311]

I have received alot of enquiries about compatability for other makes and models. Just like any other axle, it will require work to install. They are not going to bolt into anything else.

For TJ's, YJ's they are narrower and axle drops on the wrong side of the vehicle. Alot of Dana 44's would be better canidates for those jeeps.

So what you're trying to say is my YJ is far superior than your toyotajeep.

Yep, that is exactly what I was getting at.

[jeepinboy70]

I put a set of 84 yota axles (4cyl p/u) in my 93 yj. just needed to get offsets on the rims to make up the differance. But, I also have a chevy drivetrain in it with a d300. Was a lot of fun doin it, especially when i was told "you can't do that!" lol...
I've got a detroit in the rear, open front. 4:11's. 35" boggers. I've had a couple of ring gears in the rear that I gernaded, but other than that. I love em! Goin on 4 years now.

What all is involved in putting ifs hubs on a 79-85 front axle? Im looking to get a little more width out of mine. What all would i need for parts

[aimmotorsports]

sky-manufacturing has a kit for like $200. but you still need hubs. im looking into it. seeing if i can find something cheaper though...

[Mud'N'Truck]

O ive seen that before. I thought it was somthing different like putting the whole ifs knuckle assemble on there or somthing.

[Haggar]

Or just use spacers. Either way, the leverage on your bearings and scrub radius are the same.
