To add to wit

You say

"Technically you can hold the driveshaft with your hands (rear) and the jacked up wheel will turn freely."

 

If one wheel only is off the ground...

the drive shaft will turn when the wheel is turned.

 

Aye?

 

No gravey with your biscuit either.

One word of warning, a failed AWD unit, manual or automatic, can make for some very scary handling in rain or snow, so adjust your driving accordingly

thanks for the tip....we have only gotten 1 pretty good snow fall so far and it worked great in that.....

Hey WA....i was just looking over this post again and i saw were you said the viscous coupler was a sealed unit.....isnt the coupler surrounded by a think fluid?......if i were to replace the coupler how would i get the fluid back in there?....also you are refering to removing the tailshaft houseing NOT the transfer case houseing?....how do you tell which is which?....is one behind the other?......you seem like one of the right people to ask these questions too....you do answer the majority of my threads with knowledge.... again thanks for your help.

The viscous coupler is a sealed unit. Changing trans fluid will not effect it.

 

 

this is NOT true

the coupler rides in trans fluid and is controled by fluid pressure

changing the fluid can and usually does help

 

but i have fixed blown AWD that had broken gears from towing

and trashed clutches from mismatched tires

 

and if the torque bind is noticed soon enough, and the cause repaired

can usually(75%) be cured with fluid change/flush

 

just my 2 cents

i do have 2 4eat's torn down at the moment for coupler repairs

so i might not have any clue as to what im saying

also our subaru's do not have the traditional transfer case, like chevys or toyotas, the transmision contains all these parts in one(mind you VERY heavy) conveinent chunk o alloy

i have a 5spd........so are you saying that the clutches are indeed bathed in gear oil.....i did do a trans fluid exchange about 7000 miles ago........what do you know about the Visc. Couplers in the 5 Speeds?.......thanks in advance....

Sorry, but the viscous coupler (manual trans) is a sealed unit, unlike the clutch pack (auto).

i stand corrected, i was refering to the auto

ok but the question still remains as to how to get the fluid back into the tailshaft houseing after you replace the visc. coupler? and how to identify which exactly is the tailshaft houseing?

well the trans tailshaft is at the rear of the trans

LOL

 

basicly follow the drive shaft foward and when you hit the cross member you found the tailshaft, its directly above the crossmember

support trasmission(pipe on a floor jack) and remove crossmember,

remove trasmission mount,

there will be 10-12(count) bolts going around the trans(12-14mm)

and the top ones will be a bit*h(woble socket/long extension)

beyond that i dont know

i havent done this repair on a manual

a whole bunch on 4eats mostly of the 96-99 vintage

thanks for your help and knowledge scrapdaddytatum.....just trying to figure out how to do this the right way before i get involved.......

The new viscous coupler comes with fluid sealed in it.

 

You don't disassemble the VC.

 

The only part of the trans. that needs to be removed is the very back part of the housing. There are 9 bolts holding it on. The shift linkage yoke needs to be removed. Just knock the roll pin out.

 

I'll take a picture for you.

do you have access to a lift???

thank you very much WA.....thats the kind of info. i was origionally set out for....still a broke school kid so when i start to tackle this project ill most likely make a post.....

This is a pic of a transfer case I had laying around.

 

You do not have to remove the entire transfer case.

 

 

As I said..............9 bolts, shift linkage yoke, everything eles to get to this point should be obvious.

 

Once tail housing is off, you see this.

 

 

The output shaft with the bearing and gear pulls right out.

Below that is your viscous coupler. It will pull right out also.

 

This is your viscous coupler.

 

 

Pop in an new or good used unit, reinstall every thing in reverse order.

Really a very basic easy job. No special tools or press needed.

If you buy a new VC, it will come with a new bearing already pressed on.

thanks

now i know

thanks a bunch WA that is much simpler than i previously thought......

Great pictures!!

 

Talk about "worth a kiloword"

that's a megaword!!

How did the replacement go, I am guessing this is whats failing in my transmission.

So this is a great thread to help with replacing the VC but the pics aren't showing up. Anyway to get those pics up again?

Asesapie,

 

Got your PM.

 

If I have some down time this afternoon I will take some new pictures and post them.

The VC changed in 96-97 years from a stacked clutchpack with plates and diff. To sealed VC that is unit design I have been fixing the late model ones by installing a early model one in place have to change the whole rear assembly of trans but get a better unit in the end. Jaming up when trying to backup is the snap ring on VC poped out getting between the teeth of the awd transfer gears. Makes a mess seen this many many times bad VC unit
