OMGHi2U 5 speed transmission/differential failure

A while ago I started hearing very loud snapping noises when turning coming from the mid/front of the car. It is worst when tight turning under power. I hoped it might be my CV axles but I replaced them with no change. I suspect my front differential or transmission has failed. My transmission also doesn't like going to first unless I am going dead slow, and pops out and grinds in reverse. Am I correct in thinking it might be differential? And is it possible to fix or replace the differential without dropping out or swapping the whole transmission?
07 turbo 2.5L wrx.
Thanks!

Step zero should be a fluid swap. Drain. Fill with 100% Redline Lightweight Shockproof. If you want to save some pennies, do 2 qts then fill with cheap non-synthetic fluid. You should then be able to downshift into first at 100 MPH. If the other noise does not magically get fixed, the cheap fix is likely a new center differential. They are cheap used and can be swapped out without dropping the trans. Front diff issues are a drama festival and you are better off swapping out the whole trans as the front requires a rebuild.

thanks for the advice. I never did a fluid swap because the fluid looked brand new, turns out it was awful and all the junk goop had settled to the bottom, but unfortunately the problem is still there. I actually noticed that on sharp turns the car feels like its braking and the wheels are skidding a little bit.

Read my post again. It is not a fluid swap. It is a SPECIFIC fluid swap. Use that fluid.

Default 09 Impreza 2.5i Hatchback High RPM?

I've recently gotten ahold of a 09' Impreza 2.5i. I am new to Subaru so this may be an over thought concern/question. Is steady 3500 RPM in 4th gear at 60 MPH normal? and if so, should I go into 5th to cruise at that speed? the car seems to want to cruise at or around that rpm. something in me just feels that is too high.

5th is ALWAYS your cruising gear at highways speeds.
