I needsa new diff. It grumbles, loudly, when I let off the throttle.

04 WRX, 5 speed, 140K on the odomter, car is a daily, some action here and there (absolutely no redline launches from a stop etc. though), don't expect to break 350 wheel horse after all planned mods and tune.

I am the 4th owner, and previously have had to deal with snake in grass problems from the previous drivers. Looks like another scaly is saying hi now.

Should I rebuild or replace?

Recomendations on where and/or how to go about doing that?

I just had to rebuild the rear diff on my 03. Spider gears took a crap, so I decided to throw a limited slip in it. I went with the Cusco 1.5 RS. Car drives great now, but slow tight corners it is loud as hell. It doesn't bother me too much, but she hates it. I tough about buying a used one, but you never know what condition it is going to be in. I'm in Santa Clara if you want to see what it sounds like.

At a glance the Cusco looks about $1300, and I haven't that kind of coin at present :[. Might be cool to check out nonetheless. I'm in downtownish San Jose.

Is the noise from some kind of dog gear setup in the dif? I find I don't know much about some parts of the car until I want to upgrade it or it goes wrong haha.

I'm down for a cheap/workable solution for now, hence the used/rebuild question.

any reason why people are opting to buy Clutch Type LSD's instead of a Helical / Torsen type like Tomioka, or Quaife, Wavetrac? not available?

Ye olde unabomber FAQ seemed to point to a Torsen differential for most applications, and others as more akin to coilovers. Look how many get coils just because.

Just replace it

For reasons of cost, convenience, or both? Not challenging your response, just curious why.

Anyone got a diff laying around ?

Cost mainly.... You can find a wrx diff for fairly cheap... <200 dollars.... Unless you can rebuild it yourself and not pay mechanics rate.

You can find a few diff's for sale here or on nasioc. For reference I sold an r180 sti diff for 300 and that's about the price they go for. A wrx diff is much cheaper

I'm not sure what you decided to do, but I just switched over to the Cusco LSD oil after the 500 mile break in and it is quiet and smooth now.

Nothing yet, though I am gonna get a (hopefully) low milage diff to swap in sometime soon. Bills are killing me, had to pick up another job.

Good to know though. I had some issues previously with diff clunk (independent of any wear issues so far as I knew), which poly bushings and heavier fluid helped a lot with.
