Smallest/lightest live axle LSD diff you can get?

[Norbie]

It is pretty much assumed the axles will have a limited lifespan if you put any camber on a solid axle.

[cooter]

yeah thats what i was thinking cause the solid axle would always be flexing as it goes round.

i think there was a post on PF suggesting that with the splines cut with a subtle taper you could get a measurable amount of toe/camber. But the pro way is to include a CV joint somewhere on each side (is how the super taxis achieve it as they run a live axle.

[bigmat]

i can tell you what happens when you add to much toe in you smash your gears and cause bearing problems and so forth. we just pulled hypo23 diff apart for rebuild and housing was out by some 13mm toe in. plenty of debree in there to but from our inspections the axles were not bent.

chuckster can you add light to these cv joints

cheers mat

I plan on having about half a degree of toe and camber, I figure with something that subtle most of it would be taken up by the slack of the spines. Also I don't think the axles would be what goes first, they are designed to twist in torsion all the time, I would think they could handle stress in the other direction.

i have a small t series i dont know what its from, te71 maybe. i wont be using it.
its disk to disk 1410mm 4x114.3. i think the axles are smaller than the small t series axle.
this one has a welded center. so it may be a lighter than the normal t series.

will probably have enough slack.
axles are designed not to twist.. thats how the car goes forward
but they are not designed to have cyclic point loading on only a couple of the splines at any one time, so the load on each spline is magnified much beyond what they encounter even in a stock situation.

assuming your spider gears are able to be held in the same place... otherwise they will be twisted and change their loading (probably better than cyclically loading the axles) probably such that the loading of the other spider gears will go loose-tight-loose-tight as the diff spins, so might induce a bit of chatter and wear...

if worried, put two axles in the diff centre when out of the diff housing, and push them forward to have the angle you want and then spin..

as everyone's saying id recommend the t series

i got a t series diff with r31 calipers ready to bolt on, here doing nothing.

the complete diff with calipers brackets weighs roughly 25kgs by feel

lsds arnt to expensive for the t series

cheers

fixeruperer: I don't think the TE72 came with disks at any point, maybe its an RT141 Corona diff? I hear they came with T center as well with disks.

oldcorollas: I will try exactly that thanks.

te71 (jap with efi 2tg) came with a disk brake t series diff

does this diff have to be a toyota diff? as i just found out that (apparently - yet to verify) ausy suzuki vatara's have a 5 stud diff which is supposedly lsd factory.......... small, light diff.... low ratios etc - could be a go-er??

[Sam_Q]

ah I stand corrected. The Vitara diff sounds interesting and as you say I image the stock ratio would be quite tall.

What chassis is this going into?
