Re: New 04 STi owner!

Thank you! I think rockauto sells those axles as well! Maybe I'll get PS pump and axle from rockauto for now and then maybe rebuild the OEM pump at some point.

Re: New 04 STi owner!

anyone have experience with rock auto replacement axles or PS pump that would make them recommend not to use them?

Think I'm gonna place the order tomorrow unless anyone has anything to say.

Also the "ram" section of my intake is no longer there... so now it's a hot air intake, with the snorkus still attached.. should I remove snorkus and run like that, buy new intake, or is there another option? I really did love hearing the turbo spool up in my wrx which had a perrin SRI.

anyone have any experience?

if your wondering why the ram section is gone, the PO broke the bolts that hold it in place, and he didn't include it with the car either, he prob threw it in the trash because he included everything else, extra floormats, factory shifter, and bushings, factory downpipe... or he just forget about the piece of intake... idk

Source the funnel section from the forums, it's cheap and definitely helps a ton with the IAT. Someone actually tested this on NASIOC and it was a pretty significant difference. If the bolts are broken inside the holes then you'll have to drill it out and maybe re-tap it. The GD intake is not restrictive at stage 2 power levels (possibly better designed than the GR intake) so no need for a CAI, especially if you can't tune for it immediately.

I asked previous owner if he still had it laying around...

Only reason I want an intake is for the sound lol I love being able to hear the turbo spool, all I hear right now is the loud ass exhaust lol

Hopefully diff gasket, sensor, and vent valve will arrive today. I ordered the axle and PS pump off rock auto this morning.

Re: New 04 STi owner!

took the surtrac axle from rockauto up to my mechanic today along with all the gear oil.

The diff gasket, diff temp sensor and vent valve came later on but he was already closed.

I'm hoping to have her back next tuesday or wednesday.


still have more things to sort out tho..

gauges
electrical nonsense
valve cover gaskets done the road
struts
winter wheels?/tires

and more stuff I'm currently forgetting

Re: New 04 STi owner!

ok so I am completely confused on this axle situation...

subaru parts guy told me the part number I need is 28321fe001

can anyone tell me if this has two male ends or one male/ one female?

according to the screenshot I attached for my build date, I need a male/female

Re: New 04 STi owner!

also buddy says I either can do two new flanges for exhaust or get a aftermarket midpipe because right now I have aftermarket downpipe, stock midpipe, aftermarket catback lol

any recommendations on midpipes?

Re: New 04 STi owner!

Just get under your car and see if you have a pussy axle or a wang axle.

Pussy will have a pin through it to hold it to the stub coming from the tranny. Wang axle has the stub attatched to it, and you just pop it in the tranny.

Re: New 04 STi owner!

He says I need male on both sides. I just ordered one. The confusion is on partsgeek.com it says for my build date that its should have a pussy one but he's saying I need a male... idk.

Re: New 04 STi owner!

That's the confusion. My build date says I need female but my mechanic says I need a male

What's your build date? Might need to adjust the original thread as it was never verified by Subaru. If close, there could be overlap. And/or if not original owner, could be swapped.

Re: New 04 STi owner!

Build date is 04/03.

Not original owner but I was not informed of any swaps. He barely even did the maintenance let alone but in a new trans

Re: New 04 STi owner!

Yep you should have pinned axles.

Did he pop it out without removing the pin? The stub does pop out of the differential just like '04 and a half and later if the pin isn't removed. Just a thought.

Re: New 04 STi owner!

Look back at the axle images in the build date post. The pinned axles look distinctly different at the trans diff side, the have that hat shape as seems in the images.

Re: New 04 STi owner!

I just need to find some time to get under there and change the oil while I am at it...

I wake up too late and then I have things to do and when I have free time it is already dark and cold and windy out.

So far the car is holding up good tho.. I've been beating it up the past couple nights...

Still haven't found anyone to race yet lol

Re: New 04 STi owner!

So I'm 99% sure my mechanic was right. It looks like I have the splined axles...

Here are some really shitty pics I took
Didn't feel like jacking the car up...






Also I checked oil and it was a little low, in between L and F so not dangerously low... and the car was still warm so I don't think all the oil had drained back into the pan...

Good to know I haven't been starving it of oil the past couple nights of shenanigans

Re: New 04 STi owner!

What I cannot see is the mating surface between the axle and the trans case. Looking to see what is shown in the second removed axle pic here=> http://www.iwsti.com/forums/2719619-post1.html

I going to bet a $20 that your axle is pinned based upon being built a month after mine and the fact that for almost 12 years I've slept, dreamed, worked in and been cut by various STI's. There is no way if original and never touched that that axle is not pinned.
