rear differential compatibility for a 99 outback?

Featured Replies

can anyone tell me what years for sure would be compatible with my 99 2.5 MT outback rear differential?

thanks a lot.

well, you have a r160 rear diff, so, any other r160 will work

just find out which  ratio you have, and select accordingly.

As said above, as long as the ratios are the same as the tranny, the diff will work.  I just bought a new tranny with a matching diff to put in my outback from a 97 impreza.  

 

what years for sure would be compatible with my 99 2.5 MT outback rear differential?

the 99 MT 2.5 cars, have the 4.11 final drive ratio.

96 - 99 ej25 cars, MANUAL trans - all have the 4.11 read diff final drive ratio. (not sure about the impreza RS)

 

so you can use any of these.

96 - 99 ej25 legacy manual trans - outback, GT, forester 

98 ej25 forester manual trans - all (probably 99 as well)

 

but you can also use and rear diff from the ej22 & ej18 AUTO trans cars, 95 - 99, 

including

95 - 99 ej22 legacy auto trans - L, LS, Brighton

95 - 99 ej22 imprzas auto trans - ALL

93 - 97 ej22 impreza autor trans - ALL

 

 

why do you ask?

because my car i bought it from a guy who had run it over a curb

and its been a journey figuring out all the damage

it needed bearings and brakes my first mechanic told me

which was ok it probably needed them anyways but the right rear wheel was

still at such an angle it couldnt be aligned, so i took it to another guy a body/frame

shop and he said right off it was the spindle.

now the rear diff has gone, and my regular mechanic doesnt want to replace the parts

hed rather just replace the whole thing. ive found one for not too much 125 or so.

and thanks everybody and esp you john i havent been on here for a while and i

see youre still the font of knowledge and help you always were.

gotta love usmb!
