Hi all , as most know L series cars have positive front camper std which is a cornering and tyre wear problem . I'd like to make extended front control arms to get the camber neutral or a tad negative (0 to -1/2) but drive shaft length can be a problem .

 

What I need to know is which other shafts say from Imprezas or Legacys have the same splines either end as L or XT turbo ones and how much longer they are . It has been suggested here in Australia that there are a few variations in Liberty (Legacy) shaft lengths and something like 20-30mm longer than L/XT ones .

 

Thanks in advance , cheers A .

Why not just elongate the top bolt holes with some form of "lock" and adjust the top in?

or rig a camber plate?

 

changing from +1 degree to -1 degree will not need longer CVs... it's not a whole lot there...

 

Ohh and camber is typically not a huge tire wear issue... not in such a light car anyhoo.

all EJ series shafts have the same splines on the outer ends (as other EJ shafts), which is quite different to the EA. so yes, newer WRX sedans have longer shafts due to a wider track, but the axles will not work with an EA 4-lug hub.

 

all Ea82 shafts are the same length.

 

 

I'm with the king here. strut tops are virtually identical (interchangeable anyway) between EA82 and EJ. so you can get camber plates for a liberty/impreza and put them in your RX, although you may have to drill 3 new holes to get them oriented correctly.

Well I was talking to a Subie nut in another state earlier (original Mr CrossBred) and he said that we have Liberty gen1 cars with the same splines both ends as the L turbo ones . When they were getting aproval on their brake kit they actually had longer Liberty shafts in it with std length arms and they just didn't bottom out at the DOJ inner end .

 

I'd like the wider track for other reasons so I'll have to pull a few shafts , remove the DOJ and compare lengths .

 

Also with the right spline axle the Liberty and turbo L outer or CV joints interchange .

 

Just need to find how much longer the "correct" axles are so we can play with arm lengths to get the camber/caster right .

Chux I'm stunned..lol

by outer ends do u mean the outboard joint that slides into the hub, or the outside splines on the axle shaft?

 

Concerning the ea stuff, I have seen two general lengths for L-series shafts one for automatics and one for manuals (there are actually four lengths as the larger diameter axle shafts are generally shorter than the smaller diameter axle shafts) oh and of course xt6 axle shafts are different lemgths as well

outer splines, as in the ones that slide into the hub. so an EJ axle could not be used with an EA hub.

 

I've never noticed any difference in axle length. swapped all kinds of combinations (FWD N/A 3AT, FWD 3AT turbo, 4WD D/R, 4WD 3AT). granted, I've never measured any of them....so I suppose it's possible....

 

also, XT6 hub splines are different than EAs. so those don't help.

I'll have to quantify which part I call what .

 

I see a front drive shaft as three sub sections , firstly the gearbox end joint or DOJ , secondly the axle shaft , thirdly the CV joint incorporating the hubs stub axle .

 

Also yes I do realise that the L turbo and Liberty CV joints are different but share the same female spline size where they locate over the outer end of the axle shaft .

 

Now from what I can tell L turbo and early Liberty/Legacy gearbox male stub shafts are both 25 spline so they both must use the same identical DOJ . If this is the case then the splines at the inner end of the L turbo and Liberty/Legacy axles must also be the same .

Now provided the spline size is the same at the outer end of the axle then it should accept L turbo or early Lib/Leg CV joints .

 

This is the combination I'm looking for because essentially I wind up with a longer axle that can use L turbo CV joints now and early Lib CV's later when the CrossBred kit goes in .

 

I'm just trying to find out how much longer the early Lib/Leg axle shaft is with the same spline sizes either end as an L turbo axle shaft .

This is not true. ALL EA82 axles are the same length. There are a total of 4 variations of shaft diameter and joint size, but they are all the same length.

 

The only thing that makes an EA82 axle not interchangable with any other EA82 axle is the spline count on the inboard joint, where it mates to the trans. Either 23(all non-turbo, 3at turbo) or 25(MT turbo, and 4EAT turbo)

The latest information to hand is that RX (L Turbo) and a couple of variations of early Liberty/Legacy front axle shafts have 25 splines at both ends - the male ones on each end of the axle shaft itself .

 

L Turbo shafts have 3 rings to identify them .

The 25 spline Liberty ones have three similar ones , or a second variation has a fatter shaft which tapers down before each side rubber boot . The second type has one ring in the middle of the shaft .

 

At least now I'll know what to look out for .
