XT6 drive train

[XT6 NOMAD]

Hy new to sight not to subbies. I have a 90 XT6 off/on road. aka(XT6 Nomad) wondering if anyone knows if the rears in them are limited slip or anything special about the drive train?its an automatic 2.7 it seams to hold the road like a electric slot car! even in the snow....I have driven subs for a long time and never had one hook up like this! and a controllable slide! yah:headbang: We get alot of snow in northeastern Vermont and we run the power lines, back roads and my race track on the front yard. You wouldn't think I was a 46 year old man. would yah? anyway im building this one up the old school way. we used to road sign skid plates cut fenders, heavy springs/struts, lift kits and tires.

There aint nothing like being up on a mt top in 12 inches of snow and not worried about it. any help the train would be appreciated. Krazy Man.

The fsm's show lsd's were available but ive not seen one yet on the xt6's I have and have checked out. Youll find a sticker on the back of the rear differential and if its never been disturbed there is a tear off of sorts that will expose it, it will either list a ratio or say lsd.

i've owned like 2 dozen XT6's and seen lots more, never seen one with LSD. but supposedly they were an option.

 

yours won't be LSD unless you're insanely lucky.

 

but any EA series LSD isa direct swap, i've got like 3 of them. and they are always the 3.7 gear ratio variety which means it matches the 3.7 final drive of your XT6.

 

they are a clutch type LSD and take a special fluid (or additive). they are locked up until a certain point and allow give. they're my favorite style of the easily avialable subaru LSD's.

 

check out subaruxt.com, most folks are members there and here, but we're all XT owners. let me know if you have any registering issues.

Hello XT6 Nomad and welcome to the site. A gentleman from the Subaru-SVX.net site (TomsSVX) converted my XT6 to have LSD. He was attempting to convert the XT6 to a 3.70 gear to 4.44 gear. He matched up the SVX CV axle to the XT6 CV axle and found they were the same.

I have no problem pulling the valve body out and transfering it to the new trans. The TC is easy.

Just an update on the rear... THE CV'S ARE THE SAME SIZE!!! This means I will be able to fit an SVX carrier into the 4.44 rear diff to allow him to utylize the LSD!!!! Very cool... parts are running through the parts washer now. Then the CV's will be rebuilt with SVX guts as his XT ones are toasted. SO this is very cool. Been wondering about this since he prompted me with the job a couple years ago... Looks like it is all coming together

So if you are looking to do this, it can be done. I can't do it but guys like Gary and the others here could probably do it blindfolded and asleep.

 

 

Hey Gary,

Did you notice any difference in the way your XT6 drives with the LSD installed?

Hey Gary,

Did you notice any difference in the way your XT6 drives with the LSD installed?

it's great in the mud and snow offroad for what i do, i can tell it helps on occasion. easier to pull another vehicle out when on slick surfaces, easier to start in really sloppy stuff without starting a rut, etc.

 

as for normal driving and performance i've never noticed any difference at all. but i don't push the limits when it comes to handling, performance, and suspension so i wouldn't know what to tell anyone about that. i think i've *heard* folks say clutch type LSD is bad for certain kinds of driving because it increases "pushing" or something, but again that's just from memory and not something i'm familiar with.

I haven't looked at the rear-end yet. Its scary on the pavement, it was pushing bad it felt like it i was on the edge of maxed out on the pav. I was passing a slow car so I wound it up and figured out quick its bad on the road. I think its because the electric power steering ( its going out) is making it drive hard on and off road.

I was walking all over it doing some snow wheeling in 16 to 20 inches of snow up this sweet mt. trail. This is why I know its not a normal subbie. Does C 10 chassis mean anything? I herd that the XT is the only one with it? Thanks for all the help. what tag am i looking for on the rear-end? Damon

There should be a silver tag right on the rear diff (if it hasn't fallen off) that will say LSD on it or it will give you a gear ratio. Also welcome aboard I also live in VT! Just north of Montpelier!

Stickers fall off.

 

To see if you have a LSD:

Jack the rear wheels off the ground.

Rotate one side by hand.

If the other wheel turns the same direction,you have a LSD.

Damon - sounds to me like the car might have torque bind. That's a problem but would actually give you excellent snow traction as it causes the rear transfer clutches to be "locked" together giving you full-time locked 4WD front to rear.

 

You'll want to figure this out quick as torque bind can cause damage to the drivetrain and cause the clutch hub inside the rear extension housing to shear off.

 

Torque bind would experience issues on pavement, mostly a binding around sharp turns on dry pavement (steering wheel turned to full lock), and possibly even wheel chirping if the binding causes one tire to slip......and probably poor performance - like pushing.

 

There are two failure modes for torque bind - the duty C solenoid or the transfer clutches. The good news is they are repairable without removing the transmission.

 

you can install the FWD fuse in the FWD fuse holder on the passengers side of the engine bay. if the car doesn't go into FWD then your Duty C solenoid is shot. If it goes into FWD then your clutches are sticking.

 

The C10 chassis means next to nothing functionally speaking, certainly won't help here.

 

I've driven XT6's for 18 years now and they really are excellent in the snow if you throw good tires on them. It doesn't make any sense to me, maybe it's just because I've owned so many, but they seem better than any other model in the snow (all things being equal, like tires).
