Default front differential drain plug

Is it pretty hard to loose the drain plug of front differential?

I used a T70 bit and a torque wrench. Even the torque is at 70 ft-lb, I still couldn't loose the plug. It surprise me a little bit considering the tighten torque is supposed to be set at 32.5 ft-lb.

Does the drain plug follow the normal "righty tighty lefty loosey" rule? Any suggestion PB-blaster? or 18" breaker bar?

Btw: Any one knows the part-number of the gasket used on the drain plug?
My dealer couldn't find the gasket for me.

Re-use the washer.. it's a good copper one.
Standard threads. Sometimes they are tight.

And you really should never use a torque wrench for loosening, it damages them.

Exactly

Expect to apply 2,3, or 4 times the torque to loosen.

You will need an 18" breaker bar and good leverage to loosen it. Ramps are great here.

Re-use the copper washer.

I thought the torque on the front diff plug was supposed to be about 51 ft-lbs? Oil pan is 32 ft-lbs and AT drain plug is 19 ft-lbs. Unless there's a lot of difference between the 08 OBW and the 09 Foresters.

Newest front diff washers aren't copper any more. Just did the wife's car front diff last night and the washer looks for lack of a better term, odd. Its metallic, but not a chunk of steel.

Well, I guess aluminum is cheaper than copper.

Any opinions as to whether or not I should I retorque, replace, or leave alone the aluminum one on the front diff that I over-torqued?

I might break it free and retorque it to make it easier to remove next time. But I would leave the washer alone.

Thanks, if you think I can get away without replacing the washer, I'll give it a shot.

I've leanred with hers that its a tad over 5 cups that come out when I do it on the ramps, and I wouldn't be worried about reusing the stuuf that I just put in.

Actually, the stuff that had 15k on it was just about pristine. Makes me very happy that hings are wearing so good.

No issues reusing the crush washers as long as there is no debris on the mating surfaces. I wouldn't do any thing more then break it free and then retorque it. Again, my only reasoning in doing that is to make it easier to pull out after the next XX,000 miles.

I agree. By the time that aluminum corrodes I'll probably need a blowtorch. I'll retorque it tonight. Should have looked to see the torque for the different type washer, just didn't think about it.
