Quick question, both cars are 2000 year.
Ones an outback the other a standard liberty, both duel range manual.

Will the gearboxes be the same ratio, in getting confused reading the stickers.
One is H9-TY574XFADA
The other 55-TY574XF** (BAA I think)

Any ideas?

I'd say probably not.

You might have to see if you can mark the crown wheel and count the teeth, then do the same for the pinion shaft, then workout what you have.

If they run different diametre tyre (not sure) the diff ratio could be different or the speedo drive gear could be different.

Physically it's a direct replacement...

took a gamble, slapped it in.... no binding or funny business, so the ratio must be the same.

now i need to track down a mysterious sound under load, like a heat shield touching the tail shaft or brake backing plate touching some where.... i hate working on friends cars.
