Front Diff swap Q's

[ironoxide]

Hey, i've got a '92 Legacy tranny 3.9 Ratio. bolted to an EG33 in my '89 XT6. I didnt want to have to deal with driveshaft shortening so i took the center diff off of the xt6 tranny and installed it on the Legacy tranny. in order to do this i had to switch out the front diff imput shaft (i also brought with it the front diff). Now i am wondering what is protocol with Shimming these gears correctly. It seems to be a bit to tight at the moment.

 

Anyone with info would be greatly appreciated.

 

Thanks

I'm a bit confused; what's the ratio of the front diff? I hope it matches the rear diff ratio on your XT6.

Yes, the front diff came out of the same tranny as the Center diff, and i have not changed the rear diff. everything is as stock (other than the imput to the center diff.) Ratios

So, I have read the FSM for my xt6 and i believe the procedure to be the same (as the gearset is not all that different).

 

I Looked for a Stamped number in the ring gear and the pinion gear, none to be found, apparently that means that there should be no shims to hold the pinion gear shaft "back" from the ring gear.

 

after that i bolted the trans back together and still had the same problem, though it was reduced. I then proceded to adjust the ring gear "sideways". i got the gear to the point that it now hardly makes any noise when turning, and the "pulse" i felt while turning the input shaft is all but gone.
