N00b Axle Qs: Upgrading from T283 to F series live axles

[irishtwincam]

Currently own a JDM import 1984 AE86 with T283.

Looking to upgrade the axle to F series painlessly in the coming months

I'm aware the panhard rod needs to be fabricated.
Spring perches may need to be moved, also shock mounts may need moving.


-Main question is, Do the F series 4 links line up with the OEM 4 links?

Welding in washers to reduce/enlarge bolt holes sizes not withstanding?


The following axles seem to be the best of the bunch to go for.
Disc brakes to begin with, can easily swap CWPs and TRD/Altezza LSDs drop in.
A 1410mm wide one would be handy too.


-Can someone confirm these are the right axles to choose?
-How common are they in Aus?-
Who breaks and would be willing to ship these axles to Europe?

F082: Live Axle 7.5 inches, 4.111:1, 2 pinions, open (non LSD)
4x114.3 Solid Disc Brakes. 1365mm to 1410mm wide.

From: Corona - RT104
Comments: GT model corona. some have LSD

Both of those axles will work, but both are rare as hens' teeth. You'd be better off going with something more common, like YR22 Tarago.

Nothing will come close to fitting your car though, you'll need to cut the mounting points off the AE86 axle and weld them on the new axle using a jig. Any decent engineering shop will be able to do this.

My mate picked up a celica supra axle for his KE70, the 4 trailing arms seemd to line up with the axle, except he needed washers with smaller hole welded onto the axles 4link mounting brackets.

I never got the chance to measure the distances between them but it looked ok at a glance. I figured since most of these cars (coronas celicas etc) came with T or F series axles as options, then the 4 link mounting brakcets would be the same distance apart, with only the panhard rod really needing fabrication in the links department.

Spring perches and shock mounts aside, the 4link mounting brackets on the axle casing should line up on most/all F axles where there was a T series option in that family??

You need to talk to Mark (AE25). From his website -

Entered 'project bengal' drift day last monday with fellow ToyCrazy members. Mad mish as usual. Have bought and installed a TT132 (or RT132 Corona 2000 GT) 'F series' 7.5" disk brake diff. It measures 1415mm wide and has 10" solid disks and calipers identical to jdm ma45 celicaXX (has #1402 on caliper). Axle bearings are same as te71 ie dac453572 and backing plates have same bolt pattern to housing so parts can be swapped from T series 6.7" disk brake diff and vise versa. Many things bolt up like sway bar same as te71, shock mounts in same spot, bottom diff links in same spot, diff links are same length, te71 handbrake cables bolt up, diff air vent and brake lines in same spot.. The differences are: spring perches are a smaller diameter and sit slightly wider. top links are wider by about 14mm ea side, the diff link bolt holes on F series diff are 14mm compared to te71's 12mm, so i'm making up custom nolathane bushes with 12mm bolt one end of diff link and 14mm bolt on the other. The panhard rod is roughly 40mm out from te71 diff so have temporarily shortened an MS112 Crown panhard by about 15mm to make it 1835mm long, also had to narrow the panhard's chassis end 'eye' to fit the ke70. Am going to make an adjustable length panhard when time allows. I'm also making offset and adjustable length top links instead of cutting and moving the top diff mounts. At the moment I've pulled the top links out wider to bolted em up which has effectively shortened them and has pulled the diff pinion angle upwards. The new top links will fix this problem.

Later on he moved the top mounts and swapped the spring mounts.
