Does the Rear Axle require 80W oil?

Featured Replies

How does the rear axle get lubed on a front wheel drive Subaru?

 

Thanks in advance!

You mean rear differential? It takes 80-90w Gear oil. 2 plugs on the bakc of the diff, one drain, one fill. Fill until the oil just reaches the bottom of the Fill hole.

a half inch rachet will fit, if i remember alittle less than a qt ,will fill it up ,

Always assure to loosen top plug prior to draining rear diff... that way you know you can put oil back in once drained...

Oh yeah, if I take the oil out and then can't get the other plug loosened I'm in trouble. Anyone have a picture handy? (I'm not asking anyone to shoot a shot, just if someone has already shot it).

 

Can I use that synthetic stuff? I think it's called jolt or shock??? Should the car have been driven prior to draining the oil to make sure it all drains, and if it's 100 degrees out, does that make up for not driving the car prior to draining the oil?

Can I use that synthetic stuff?

 

I have run Amsoil gear lube in all of mine (EA82 3ATs), never had a problem in almost 20 years.

yes the plugs can be fun to get loose, try some blaster on them first , a half inch braker bar with a pipe , should do the trick

Front wheel drive only subarus would not have a rear differential, correct?

Correct.

 

FWD manual trans uses Gear oil for the whole thing.

 

Automatics, the trans(rear) potion uses ATF, the dipstick/filler tube is on the left side of trans. The differential portion of the trans(front) uses Gear oil, dipstick on the right side of above the axle stub.
