Default Rear axles help needed.

I'm putting the LSD from a LGT into my impreza L as part of my swap. Turns out the Legacy axles are longer and don't fit through my hubs and the ends are to thick. I've read that you need LSD specific axles but I don't see any differances between the ends of the axles that go into the diff. I test fitted my L axles into the diff and there wasn't any problem. Below are pictures. If I can't just use my L axles is there any reason I can't take the two axles apart and make a hybrid? Moderators if this belongs in tranny please move.
Thanks,
Joshua
Green and clean is the Legacy

Where did you source the axles?

The 91-94 Legacy Turbo Axles I have coming look a little different:



I had originally thought the male axles would work, but the axle stubs were not in the diff I bought. I got it all sorted out with all Legacy Turbo parts as shown above.

I ran stock L axles in an R160 lsd for while without issues. There are some types that don't work. There was a big thread on this about 1 year ago.

Sorry the axles are MY05 LGT axles.

linsavy,
I'll search for that thread but sounds like I should be fine.
Thanks,

also important are the spline counts i have a good post in this forum some where
00-01 RS axels as well as most of the first gen foresters have what you need i found mine in a 98 forester

do you need the abs rings?
non abs axels don't have the notches

Ahh, ok, I would think you will be fine using your axles in the 05 diff if you are getting the L axle to "seat" in your LSD. I misread your problem as being at the diff not the hub. My 98 GT axles seemed like they fit at the diff, but I knew something was off. In my recent discussions it seems as though the newer style R160 VSLD works with the "non-LSD" axles.

^^^ If that's the case and I understand correctly, one can use non-VLSD axles with the newer R160 diffs?

I have a pr. of good 98RS axles if anyone need them. The hub ends should have no problem sliding into the L hubs.

I don't have ABS so that won't be an issue. So my rears it appears is all set. Now I'm starting to worry about the front axles I am planning on doing the tranny and engine tomorrow. I know on the L tranny it's held in by pins the LGT tranny it wasn't. Will my L axles bolt up to the LGT tranny? If not will my previous idea of a hybrid axle work?
Thanks,
Joshua

Is there a difference in the splines at the front hubs?

I know the STi axles I have will work with the 98 GT hubs, so there may be a lot of cross compatiblity in the front axles.

Storm, I dont know this for a fact, but a few people on this board have used their old axles successfully. I cannot comment more than that, as mine would not work. I have no newer VLSD to check. I believe there is a thread or two floating around in which a good description of all the diff. combos is given.

whats the bolt pattern on the LGT wheel? is it a 114?

its bigger splines? thats why it wont slide into your hub? it is a R160 though, correct?
you can easily hybrid. or use your existing axels - are you sure it wont fit up? looks the same to me. you are keeping the impreza hub though right? mutilink rear would be wildstyle though-

take pictures of the front axel inner/outer from the LGT. be cool to see what it is. good chance it fits right in, although if its too long and female trans you might need a GDB 05+ front axel.

if the LGT runs a R160 and a 114 hub, it might very well have a SVX axel (or lengthened SVX axel).

The legacy wheels are now on my impreza along with the brakes so the bolt pattern is the standard subaru on not the upgraded one of the STi. As far as I know it's the R160. I am keeping the Impreza hub, it actually is that of an MY02 WRX from when I went to rear disks the first time. I'm doing the front today so I'll get pictures, it is a female tranny I know this for sure. I'll post pictures today and I'll probably have to hybrid the axles.

actually this might be a bigger proublem
the LGT tranny has no speed sensor the car gets its speed from the abs module

I saw this in the wiring diagrams. The tranny still has a place for my mechanical speedo hook-up so I was planning on using this. I dont' see the ECU using vehicle speed anywhere unless it's getting it from the can input? The stock gauge cluster translates the mechanical into a electric signal so I can always try and use this electric signal if it turns out I need it, even though it might have to be filtered through something to give the right voltage. I'll play it by ear unless someone already knows the answer.

i believe it is on the can bus.. and the ecu has no vss input .. so the ecu may very well freak out when it sees no signal

I'll know soon enough. I was thinking of looking at the ECU pinouts of an STi ecu or a forester ecu, I wonder if the would work if I'm not able to use the Legacy one, or if I could even just get it reflashed to except certain values from my gauge cluser to tell it speed. The will be a way just I might have to pioneer the way.

i think the 04 forester ecu is the way to go ... no imobilizer, vss input, maps for all sorts of things...

i would actaully wager that a fxt ecu would run a 2.5gt w/o mods . not perfectly but still run

jaxx you using a R160 Viscous on your car?
becouse if your talking about forester rear axles fitting in a r160 Vis. it would make it 10X easier to get those, and i would be happy

I looked at the Sti MY04 and MY05 ecu pinouts yesterday and they are slightly differant. Than each other. The connectors are the same shape so they would both probably plug right in but not all the pinouts match up. The MY05 is almost exactly the same as the MY05 LGT except it has a vehicle speed sensor wire and doesn't have a few other things like "can". I don't see immobilizer wires to the ecu either but I know the MY05 sti has one.

This may be wishful thinking but the speed sensor on the sti goes to B135 #26 which is not being used on the legacy. I wonder if I were to pin in my vehicle speed sensor wire to that spot if it would read it. Thats probably a far hope. But I don't see why it wouldn't work for me to pin it that way and use and sti ecu and then the corisponding key for the ecu immobilizer, or have the legacy ecu reflashed with sti software with appropriate maps for my mods.
