Rear diff

#1

1997 subaru outback the rear wheels do not pull “spin” only the front, can any one give me any advice

We are assuming you have front drive only ? In discussing this before, my 97 manual had a viscous coupled mechanically controlled center diff. Any problems would involve maintenance of differential or parts failure. The automatic had an electronically controlled, if that’s yours, it could be a fuse or maintenance issue or parts failure. I’d check fuses first if auto and work from there. Get lucky !.

yes it is only the front and it is a auto, thank you for your reply


#4

Is there a fuse in the FWD receptacle under the hood? If so, remove the fuse and see if the rear drive works.

Inserting a fuse in the FWD receptacle disables the rear drive.

This only applies to Subarus with automatic transmissions. The manual cars are different.

i took the fuse out and the rear wheels engaged, what do i need to do to fix this problem or what is wrong?? thank you for your reply


#6

Let me guess.
Did you just buy this car?

If that is the case, then it is likely that the seller was trying to cover up a problem with the viscous coupling. That repair can cost several hundred $$ if it needs to be done.

Does the car have matched tires? If not, that is the likely source of possible damage to the viscous coupling.

yes i just bought it, the tires are a match set, but the front tires are worn worse than back ones that is why i knew the rear wasn’t pulling. but i knew when i had it on a muddy road and almost got stuck,only front tires pulling, but pulling the fuse engaged the rear… abought how much does it cost to fix myself… again i thank you


#8

I think you did fix it. Now get 4 new tires to make sure you don’t break anything.

my question is why won’t it engage in by it’s self, is there a bad sensor some where. thanks for your reply
