newkid17 · #1 11-24-2008, 11:32 AM

ok so i found out (thanks to you guys) that my pinion bearing in my front diff. is bad... so i was wondering if it is easier to replace the whole front diff. or to replace the pinion bearing only? and if i was to replace the whole front diff. how do i do it. does the tranny have to come out?is there a certin front diff. that i would need or will anything out of a subaru fit? i know that the diff. comes befor the tranny so i am thinking that there is enough room to squeez the front diff out without taking the tranny out. i really do not want to take apart the front diff. just to replace the bearing unless that is alot easier..?

i could really use some of your guyses expertees.

The trans will have to come out.

And make sure to change both the ring gear and pinion gear. They are a matched set and both need to be replaced or else premature failure is likely to happen.

ok so what if i was to just replace the whole front diff.? or is that pointless?

I believe the differential has to be one out of an svx unless you want to replace the rear diff as well.
Someone correct me if I'm wrong as I can't remember for sure if the gearing is in the transmission or the front diff. If the gearing is set by the trans and not the front diff than there are a lot of options for replacing the front diff.
