I have an 82 toyota 4WD and want to upgrade to the wider rear axle with bigger brakes. What years have this rearend I need? Is there any years that are most desireable? Thanks for any info

they went to the wide rearend in 86 with intro of the ifs

All of them are pretty much the same. Very subtle differances. Stay away from the '90's erra 4runners, because they use coil springs, and a different e-brake setup.
The Taco axles are even a little wider, but the housing seams to be a bit weaker.
Good luck, you'll like the wider running gear. I doesn't seam like much, but it feals much more stable.

If you don't want to be bothered by the wider track of the 86+ V6 rear axles, look for a 86-87 axle from the turbo trucks. It has the G292 rear diff (v6 housing/2 pinions) and 10" brakes. Same width as your current axle.

If you go for a wide one look for a 86+ v6 axle coded G294 as the diff is not only a v6 style but has 4 pinions, versus two.

Is it possible to install the 10" brake setup on a pre '86 (8" brake) axle? Is there a kit out there to do it? Or am I better off looking for a complete axle somewhere?

I've heard the 86+ 10" brake assemblies will bolt onto the earlier 79-85 axles. I also heard that T100 and Tacomas have 11.50" brake assemblies and these will definitely bolt onto the 86+ axles, if not the earlier ones.

So why not just look for the larger ones to begin with? I may be mistaken about the width of the turbo 86-87 truck axles. They may in fact be 58 inches wide too, but the two axles I saw installed in trucks definitely were G292s.

I did it. for the most it's a bolt on deal. have to pull the axle bearings to change the backing plate.
the problem is the drum has a bigger hole for the bigger hub on the newer axle. I have a shop make a spacer to fill the gap. I like it . I mite have gone with the 11"s if I have knew about them at the time butt the 10"s saem fine for how I use it now. I tow a camp trailer and have a cab-over camper too.

will those 11.5" assemblies fit a 15" rim?

WHITE_TRASH · « **Reply #8 on:** Dec 10, 2004, 12:18:20 PM »

Yup thats what they were designed for.

kjishikawa · « **Reply #9 on:** Dec 10, 2004, 07:32:16 PM »

cool I'll have to look out for those, hard to come by here. I have an IFS rear but the backing plates are all rusted out. Today at the salvage yard a guy showed me a 10" backing plate and the hookup for the parking brake was different. Instead of levers for the cable there was a rubber tubing connected sraight into the housing. How are you guys connecting the parking brake to this?

gmrwizard · « **Reply #10 on:** Dec 10, 2004, 07:45:51 PM »

I am going to have to start looking for an '86+ axle. I priced one at a yard in town today, like to fell over, 400.00 pluss complete. Did come with a 6 month waranty though.

reklund5 · « **Reply #11 on:** Dec 10, 2004, 10:32:18 PM »

You should be able to find it a little cheaper than $400....

Where are you located? I've got one here in NM that I may be willing to part with.

Central Calif. Thanks for the offer
I think I found one but got to go WAY BACK in the hills to look at it tommorrow.

reklund5 · « **Reply #13 on:** Dec 10, 2004, 10:59:47 PM »

Dude- WAAAAYYY back in the hills is where the good stuff always is! Those mountain guys hoard all the cool stuff and usually sell it cheap!!!! I've found all sorts of cool stuff like that around here!

Good Luck

Yah your right. Momentary brain fade. WAAAYY back IS usualy WAAYY good.

If you go for a wide one look for a 86+ v6 axle coded G294 as the diff is not only a v6 style but has 4 pinions, versus two.

I keep pondering over those "G" codes. Where do you find them on an axle that is not in the truck?

79coyotefrg · « **Reply #15 on:** Dec 11, 2004, 09:12:13 AM »

dude, if it has 6 lugs its an 8" or 'G' 3 ribs on the side of the 3rd is a 4cyl, 4 ribs is a v6 or turbo, i dont know if theres a number on the housing or not

I dunno about that. The two '86-87 turbo inline 4 trucks I looked at, with axles in them, had the G292 code on the plaque on the firewall, 10 inch brake drums, and v6 diff housings.

Look at the pics to see a visual difference in the v6 housing and the inline 4. There's more ribs on the v6, in the background. I'd look for a G294 v6 axle from a 86+ truck because it has 4 pinions versus 2 pinions.

See the other pics.

kneedownnate · « **Reply #18 on:** Dec 11, 2004, 11:25:27 PM »

Dude, Glen's completely right on this. The G code doesn't designate whether or not it's a v6 or turbo axle, all it means, and I mean ALL it means is that it's an 8" gear set. G=8", 29=4.10 gears and the 2=open diff. If you find one ending in an odd number it has the factory limited slip. If you need to know what gears are in a stock truck(or car) gimme the code and I'll tell ya what gears it has. Trust me on this one, I know, plus if I don't I call my brother who works at a Toyota parts dept. and ask him. Nate

You are correct. Nothing tells you it's a v6 or turbo inline 4 diff except you see it in the original truck (and read the firewall/doorsill plaque) or you look at the ribbing on the diff housing. I focused on G294 versus G292 because I wanted the 4.10:1 ratio. If you want a different ratio the codes will be different. Of course the last digit 2 means open diff with 2 pinions and 4 means open diff with 4 pinions.

G254 is 4.56:1 ratio with 4 pinions
G144 is 4.88:1 ratio with 4 pinions

Note that on a 1983 or older truck the pinion flange will not bolt up to your existing axles. In 1983 and older trucks the bolt pattern is 56mm x 64mm. On 1984 and newer trucks the pattern is 60mm x 60mm. In addition the bolt size is different with 8mm bolts used in older trucks, and 10mm used in newer. Since both differentials use 27-spline pinion shafts the flange from the old differential could be transferred to the new differential. The code given is the axle code and is available on the firewall of older trucks, or on the driver’s side door pillar of newer.

Marlin sells a pinion flange drilled for both patterns, or you can have any competent machinist drill the second bolt pattern on your flange using a dividing head on his Bridgeport mill.

A slight bit off subject. Who can make custom length rear axle shafts to fit a custom rear housing design?

I'm not sure where you're getting that info - but all IFS axles, 86-95, are the same 58" wms-wms. The Turbo axles are the same width as the rest of the IFS axles...

I'd already corrected my blunder... Good to see somebody else is alert too.

kneedownnate: Just to make sure, I pulled the code for my 3rd (G282A). The truck is an 86 4x4 auto. I'm assuming it's 4.30 geared. Just making sure...

That what the code equates to. Only way to be sure is count the teeth on the ring and pinion gears, do the math. Ball park method is jack the vehicle and rotate the tire and see how many times the driveshaft turns to a 360 degree revolution of the wheel.

That sounds like it's out of a 90's 4 runner. The one that came out of mine was the same way.

Does anyone have one of the 86 up axles near Sacramento? I live in Roseville, about 20 min north of sac. Really need one of these soon, thanks.
