View Full Version : Replacing a center diff on a manual?

Has anyone ever replaced the viscous center diff on a manual before?
I'm having some banging noises coming from the tranny when moving in reverse and if I have to replace the tranny, i'm going to refresh or replace the center diff also, because i'm tired of spinning the front wheels everytime I crack on it in, in the rain or snow.
I mean, for God sakes, I have a rear LSD and it is barely noticable!

I'm pretty sure you have to completely disassemble to entire tranny to get the center diff out. Usually not something Joe Schmo can accomplish in his back yard. I wouldn't mess with it when you can get a used tranny out of a junkyard for next to nothing.

Yeah, the center diff is inside the main casing of the transmission.

I'd suggest buying a PPG gearset or something, and a decent aftermarket center diff, and replacing everything at the same time. The stock Subie center diffs, other than the STi's DCCD, suck. It's possible to overload the center diff in a stock car in low grip situations and get tires to spin.
