Interesting find re: Front EJ driveshafts

Taken from the BC/BF Gen1 Liberty FSM
Why is the right hand side shaft 10mm longer and 2.8mm larger in diameter at one end, compared to the left side?
Also, why is the 2.0 turbo and 2.2L shafts 27mm shorter than the 1.8 and 2.0L non turbo?
The track should be the same, as should the width of the gearbox. Why the difference?

Maybe the DOJ and CVJ are longer?

Nice find the older boxes probably have a mild offset that may have never been noticed outside of the factory. From which FSM did this appear? Australia... America... year?

The FSM specifies both "Australia" and "Except Australia" models in the specifications section

I knew early FWD Liberty's had thicker front shafts than AWD but thought that was the only difference.

The lower spec models ran skinnier tyres and had the track width increased by 10mm so that the outside edge of the tyres remained in the same position.
Std tyres were 185, tyres for the 1.6, 1.8 and 2.0 (non-turbo) were 165 or 175. so that accounts for the 10mm difference on the 175 tyres.
On the 165 tyres (1.6l models) they changed the offset of the rim to +50 from +55 to gain an extra 5mm of width - I guess they decided to live with these models being 10mm narrower.
Why they didn't leave the drive shafts the same and do it all with a different offset rims I have no idea.
All this info was taken from the same service manual as the original post.

So is the track width difference in the lower control arms, or the actual hub?

hummmm, Always thought both side were the same. would it cause wear issues mix-matching?
Also, It would be cool to have something similar but on the spline count from the EA82 and EJ series, i.e 23-25 splines, allowing mix joints cv's to be made up so gearbox and hubs conversions would be simpler:)

I would guess neither. The drive shaft being longer would push the hub out and I assume the ball joints and rubber strut top mounts would take up the difference ? maybe the camber bolt helps as well ?

But the lower control arms hold the hub in place, not the shaft.

Gannon its been a long time since I've been in a Liberty/Legacy WSM but it may pay to check out the Pov Pac models some countries got with four stud hubs and smaller than we got brakes .
Some of their wheel and hub offsets could have been different and the very basic ones , say with optional roof , I think may have had 13" wheels .

it,d be slight difference in lower control arm and slight camber bolt adjustment
