t0ad Posted August 19, 2006 Share Posted August 19, 2006 I see mention of replacing metal gaskets on the front and rear differentials when replacing fluids in them from the vacation pix, but I can't seem to find some part numbers. Anyone know offhand? I assume I'll need one for the front drain plug and 2 for the drain and fill plugs on the rear? Link to comment Share on other sites More sharing options...
pillboy Posted August 19, 2006 Share Posted August 19, 2006 I'm not sure (the dealer changes my diff fluid), but I think it is the same as the "crush washer" for the engine oil drain plug. It is still ugly. Link to comment Share on other sites More sharing options...
edmundu Posted August 20, 2006 Share Posted August 20, 2006 On the MT transaxle, the drain plug gasket is either copper or fiber based. I have changed my front transaxle fluid about 5 times without changing it. I just keep reusing it. On the rear diff, you just need a bit of "Blue" threadlocker for the drain bolt only. The fill bolt gets nothing. Link to comment Share on other sites More sharing options...
ct03si Posted August 20, 2006 Share Posted August 20, 2006 actually the rear plugs dont even need any thread lock i have been changing diff fluid for a year at my subie dealer and have never seen one leak and as for the front diff it is larger than the oil drainplug gasket it is made of copper and does not really crush much but you should still change it every time just like the oil drain plug and tranny plug gaskets Link to comment Share on other sites More sharing options...

t0ad Posted August 20, 2006 Author Share Posted August 20, 2006 I kinda figured I could just reuse them with a bit of threadlocker .. now, to ponder on how to fill that rear diff without investing in a pump Guess I'll try a bunch of tubing and gravity.

sgt Posted August 20, 2006 Share Posted August 20, 2006 Dont use threadlocker on the rear diff plugs, use some RTV like permatex ultra gray Link to comment Share on other sites More sharing options...

Don't bother wasting time & oil on trying to pour the oil in, unless you have a 6ft piece of hose, and pour from above, while someone holds & watches underneath. Or, do as I did, just go to your local autoparts store and pick up a gear oil transfer pump. They are cheap, $7-8 bucks, and they look like an oversized pump for hand soap, but with a 12-18" clear vinyl hose attached. You can fill the rear diff in just a minute or two, without a mess, and by yourself! Link to comment Share on other sites More sharing options...

dplacen Posted August 21, 2006 Share Posted August 21, 2006 The front diff washer is made out off copper and they dont really leak. It takes a long time for that washer to wear out. On the rear you dont need anything. You just have to tighten up the plugs. However you should always replace the washer for the drain plug on the oil pan.
