Ta 22 Diff Question

[TA22RE]

Hi Guys,

I was speaking to one of the guys at Craft Diffs in Sydney and he mentioned a hilux diff that didn’t need shortening in order to fit a TA22.
Has any one else heard of this diff, and what model hilux dose it come out of?

[ONCE-NA]

Yeah its an RN2* Hilux. Its about 10mm wider though I think, so not really a problem

[TA22RE]

What year model hilux do the G series come out of? and are they the 4x4 or the 2x4 diffs

[styler]

ta22 = 1355mm hub mounting face to hub mounting face.

rn10, rn20, rn25, rn27 ?? ie early hilux 1970 -1980 ?? = 1370mm
hub mounting face to hub mounting face.
mind you, these are somewhat of a collectors item and priced to suit.

OK, so I know this subject has been done to death but I'm going bog eye'd wading through all the info.

After much fruitless searching for the elusive RNxx Hilux diff to suit a TA22 I've been offered a complete 1985 Hilux 4WD diff for $450.

Questions: will this be suitable for shortening - changing to 4 stud pattern etc etc for the '22.

Any help

If you are not going to get the narrow diff, and get a latter diff to shorten... then go ahead and do that if you want. If you are going to go to the trouble or shortening everything, then it hardly matters what you start with.

Both HiLux 4x4 and 2x4 come with the 8" G series diff. In Australia, most 4x4 have the LSD, and the 2x4 have the open centre. There are several ratios also. The diff centres that were is diesel cars have bigger bearings on the pinion.

If you get the right 2wd diff housing from the 70s ? RN2*, then it probably already has the correct stud pattern also.

[ONCE-NA]

That's probably an RN40 diff then? At 1410mm from memory it will either need to be shortened or use the right offset wheels to make it work. Changing stud pattern isn't too hard, or the mounts, shortening, especially the axels will be expensive I expect.

Pretty sure no hilux's were 4 x 114.3.
The 5 stud ones at 5 x 114.3, 1 stud is right, there is a hole directly opposite that already and just needs drilling larger to accept a stud, leaving only 2 for you to work out.

[ONCE-NA]

And most factory ratios suck for street use ie. The easy ones to find are 4.3 and greater

Hi,

keep in mind the 4x4 versions are 6 stud too! I don't think most/any of them had lsd till at least the 90's. No standard 80's hilux diff i've ever seen was lsd. Regardless, it's a factory toyota lsd so it'll be stuffed by now anyway.
