Anyone with rear axle experience ('94 LSi)

ddmd · #1 02-16-2012, 12:11 PM

Hi all. I've run into an interesting problem with my '94 LSi. The right rear axle was making some noise so, I had my local Subaru dealer replace it. Unfortunately, the right axle that came in was different form the axle that came out of mine and doesn't fit. SOA insists that the replacement part is the right one, and that the right and left axles are different (with different part numbers). The dealer then took out my left axle and it looks identical to my right. The Dealer, at this point, doesn't know what to do. Any ideas?
Are all of the rear differentials (LSi and non LSi) the same for '92-'97. Has anyone looked at both rear axles and noticed a difference? The new right rear axle from Subaru (which doesn't fit) is definitely longer with a different spline. Thanks in advance for any help.

does your car have a manual trans swap or 4.44 geared trans swap by chance?

my source (napa) says right one is 31 and 7/16" and the left one is 30 and 1/4". these are compressed measurements.
how long is your old axle and how long is the new one?

It's an automatic but They're going to try checking serial numbers on the Trans and Diff to see if a Swap was done at some point. He thinks that it looks like axles from an outback. We'll see.

I'll see if I can get those measurements

Better yet get us the number from the transmission by the starter.

OK, I'll look for it. Thanks

Hi Tom,
That helped immensely. The Transmission Type is TZ102Z2CBA-DT, which is on the list of 4.44 Transmissions on the thread. The Serial number is 188536. Is there a way to determine the Donor Vehicle from that number and, more importantly, the Donor Differential? I can then buy the right axle for it. Thanks very much,
Dennis D

Actually, I did a

search and it looks like it's from a '97 Outback. Can I assume that the Diff. (and axles) are from the same?

it could be a different rear diff..

I'm swapping in an 04 outback rear diff and I'm having to replace the SVX-Specific right rear axle and swapping it for one w/o the two splines.

Yeah it sounds like whoever did the trans swap just swapped out the rear for an OB rear diff. Just get some OB rear axles and all will be good.

FWIW, you only need one.

Rats! Found an axle from a '98 Outback and ....doesn't fit, and doesn't look quite the same. The Transmission has the number TZ102Z2CBA-DT which, from everything I can tell, comes from a '97 Outback. I've been told that the axles from the '96-'99 Outbacks are interchangeable, but this definitely doesn't fit.
Is it possible that someone mix and matched, using an Outback Transmission with a differential from a different car (Forester or Impreza)? Any ideas?

Hocrest · #15 02-27-2012, 08:17 PM

yeah, it is entirely possible that it would be a diff from a different car. How is it not fitting?

Do you have any pictures of the diff without axles attached?
