subyrally Posted May 3, 2005 Share Posted May 3, 2005 thats why they use bash gaurds on the rear diffs, they are not cast iron. at least not from the factory, not that ive ever seen on a suby.i know that the rx i have has an aluminum diff as does my impreza.

NoahDL88 Posted May 3, 2005 Share Posted May 3, 2005 the back cover is ally, the actual housing is iron, i can take a picture of the rust on it if you'd like. Quote Link to comment Share on other sites More sharing options...

Actually, they do crack just like eggs. This will save the diff in most cases but not all. Quote Link to comment Share on other sites More sharing options...
subyrally Posted May 3, 2005 Share Posted May 3, 2005 looks like im enjoying the fine taste of foot. i know ive seen all alu diffs on cars ive worked on, i guess the fact that i havent been under the cars in a while and the lack of sleep combined to make me an idiot. well, i will stand down now before i say something else that i will regret.

WJM Posted May 3, 2005 Share Posted May 3, 2005 I had investigated the use of Impreza/Legacy rear diff protectors on the RX/older EA82 cars. one of them was nearly a bolt up item. Quote Link to comment Share on other sites More sharing options...
