Swapping 92 5spd tran & diff to 95 car?

Post by dbur »

Hi,

Since my 95 Legacy wagon has a bad tranny and I have a good 92 drive line on hand I am trying to swap the tranny and dif to the 95. Both are 5spd.

I need to do the diff also since the tranny ratios between the two sets don't match.

I have both diffs out now, and though the cases look the same, there are some notable differences that could not be seen while installed.

1. The 92 diff has spline shafts that stick out in to the drive shafts which fasten with a spring pin. The 95 has splines on the axles which penetrate the diff.

Can I just swap the 92 axles to the 95 as well?

2. The rear diff bolt studs (pointing to the rear) that go through the rubber mounts are shorter for the 92 diff. They need to be longer for the 95 style mount bracket. Do these studs screw out if I put on some jam nuts and back them out, or does the diff case have to be opened to do that?

Am I going to run into anything else that doesn't match? (Haven't got the 95 tranny out yet)

Thanks.

I did the same thing on my Forester and ran into the same problems.

Use the axles that match the diff, they are the same in every other way.

I don't know if the studs are removable, I wouldn't think that they would be. I swapped the whole cover over on mine.

Thanks. I have the axles out and it looks like they can swap direct with the diff.

Swapping the covers looks like the way to go as well.

Turns out the diff rear studs backed out fairly easily so I just swapped the studs. Swapping the axles also worked out OK.

Unpleasant surprise is the 95 drive shaft flange does not match 92 diff flange. Hopefully the 92 drive shaft will swap in to the 95, or I have another problem to resolve. Would have been nice to have discovered before I had the diff swap completely done.

Don't have tranny out of the 95 yet so that still might turn up some problems. Did drain a bunch of metal filings out.
