On the gd it's a 30mm nut, but I'm not sure if the gr one is the same.

 

30mm, hmm. it seemed like the 21mm was just a bit small id guess of hand 22 or 24 mm would fit. though its hard to tell since its so recessed

 

It is indeed a 22mm.

 

ouch 140 bucks for this thing, that's an expensive mistake.

any with a GR that can confirm the larger nut size for this thing?

 

Throw me in the "snapped sensor" club. I am soooo pissed!! Oh well, live and learn. Anyone know the torque specs for that sensor? My service manual said 44.3 ft/lbs but I am living proof that is WRONG!!! I did not even get close to 44.3 ft/lbs before I felt $120 slip through my hands.:tdown:

 

Mine has a paint mark across the sensor to the housing (form the factory). I was about to snap it too I think before I chickened out of tightening it to spec. So I just lined it up to that piant mark..

 

I'm glad I'm not the only one that did this, I felt like a complete idiot today. I also didn't have a deep 22mm to get to the larger drain plug so I used the 19 to get the sensor out and when I put it back in I was also torquing to the wrong spec apparently because it snapped really easy

Luckily I found a plug to put in place of the sensor until I buy a new one. I guess I'll have the rear diff temp light staring at me for a while :lol:

 

What size plug for the sensor is it?

 

German specs: goodntight
or strip it out and then back it out half a turn

 

I fell into the same trap. Gonna see if I can glue it back together :/

 

They should have made a note in the specs that the sensor requires way less torque than the bolts. Hopefully you can glue yours back together...mine shattered into a bunch of pieces

 

It was a while ago when I replaced the rear diff fluid, but I can't recall doing anything other than unplugging the sensor; I didn't touch it otherwise...hmmm

 

You may want to recheck.

The oil level should be to the bottom of the temperature sensor hole, not the drain hole which is lower.

 

Just curious, at what mileage are you guys replacing your fluid? I'm getting close to 15k and was thinking of doing it then. TIA

 

I replaced mine at 17kmi. It came out looking very dark.

 

I broke mine too when installing Perrin rear diff cover. The cost sucked but it took like three months to get it. I just threaded the busted off end in with some sealant to hold me over.

 

I tried to do that with mine but my sensor cracked on the threads and I didn't want to risk it. Luckily, I found a nice little plug from ACE hardware in their misc bolts/screws section. It was in a box labeled automotive plugs. That has worked out for me until I grab another sensor. Just make sure you put some loctite on the plug if you use my quick fix.

 

Has anybody found the CORRECT torque for the temp sensor into the nut/well? I didn't break mine, but i did remove it instead of the two pieces as one. Can't believe the service manual doesn't even list them as separate parts!

 

I just replaced my rear diff (and tranny) oil last week. You need a 22mm deep socket for the fill plug, not 19mm.

 

I think this is where some people are running into problems. I didn't have a deep 22mm socket so I used a 19mm to remove the sensor instead. And I would assume the sensor torque is something like have of the torque the plug calls out...it's VERY fragile.

 

definitely go out and spend the $5-10 on the 22mm deepsocket if you don't have one so you can undo the primary plug.
that sensor is ridiculously fragile and costs too dam much to risk breaking it.

 

I just snugged the sensor into the well with a normal size 3/8 handle and when i checked the torque it was ~ 30 NM. So half of the well nut torque should be good.

 

OMG.. So i thought i'd do the nice thing and replace the rear diff fluid before selling my car and I do the same f***ing thing! Ugh.. how long will it take Subaru to get me this part?!!?

 

If your local Subaru dealer doesn't have it in stock, shouldn't take more than a week to get it. I've ordered all kind of things from local dealerships and it's never taken more than a week to come in if they had to order it.

 

Damn. No Idea

 

So iwas just changing the rear diff fluid and really wish I read this thread. I over torqued the sensor and it sliced right off. The threads from the sensor are still actually in the bigger bolt. I am going to buy a new sensor but im not sure if I can get the old sensor out of the bigger bolt. Any ideas?

 

Why don't people avoid removing the sensor all together and remove the bolt it's in? 22mm deep socket should do it.

Edit: Just saw you have a GD. That'd be 30MM wrench that you should use.

 

How hard is it to change out your rear diff fluid? I've never done it... (or had it done)

 

It's super easy. There's a couple threads that have pics in the How To section but it's basically just taking the two plugs out of the rear diff, drain all the fluid, then put the bottom plug back in and fill the fluid until it starts coming out the top hole and then plug the top hole up and you're done.

It's a pain getting the fluid back into the rear diff so I bought this small $10 hand pump that screws on the top of like any fluid bottle and I just use that to pump the fluid into the rear diff.

 

It's easy if you take the time before hand to have the right tools.

 

I ordered a new sensor, cost me $160 from Subaru. I don't know why my dealer charged me so much.

Anyway, the sensor comes with the bolt that it screws into. So you replace the whole assembly, not just the sensor.

 

I ordered a new sensor, cost me $160 from Subaru. I don't know why my dealer charged me so much.

Always ask if they can give you a better price. Especially if you have a general idea of what it should cost.
All the part's guys I ever dealt with either tell me they'll give me the normal price up front, or if they quote their high margin price I ask them and they usually will drop it.

 

What size sockets for the GD?

 

no... I just did a search... didnt notice the GR section...

ignore the tard in the thread :-D
