Default Front transaxle (?) seal question

Sorry if my nomenclature is a little off - I'm still getting used to the geometry of this whole thing.

I'm taking care of a few odds and ends on the 95 Brighton we picked up a few weeks ago, including changing the front driver's side CV axle. (I got a Curt hitch from the junkyard too yesterday for $30, so I'm pretty pleased with myself at the moment.) When I pulled the CV axle off the transmission/transaxle/whatever's output shaft, I noticed a little leakage, and the outer metal portion of the seal came off with the inner CV, so obviously that seal's going to have to be replaced too.

My question is this: Is there anything weird or difficult about doing that seal? The reason I ask is that it isn't even mentioned in Haynes, though they go through procedure for replacing the rear side gear seals.

Wait - I take it back. I see now that what I thought was part of the transaxle side gear seal is actually a "baffle plate" pressed onto the inner CV housing, right next to the roll pin. What confused me is that the two CV axles I fetched from the junkyard yesterday (from a 95 2.5 w/auto) don't have them pressed onto the CV, but the assembly I just pulled from my 95 2.2 w/5speed does.

Is this baffle plate just meant to keep road crap from flying into the seal?

Are they used with standards but not with automatic transaxles?

Definitely just a dust shield for the axle seal. Not sure about the AT to MT difference I have rePlaced axles in manual foresters that have them. More commonly included. Possibly older part design won't. Probably won't notice a difference.

I would try to refit them if i could as they are there to protect the seal from dirt which will most probably cause the seal to leak further down the track.

It does sound like the very end of the axle came off, those are just kind of punched on there and not welded so that happens sometimes.

If you really do mean the seal around the output stub shaft from the differential, those are a little tricky. There is an o-ring behind the retainer too. You have to turn that retainer off, counting the turns, because it has to go back the exact same number of turns or the backlash will be incorrect.

Thanks very much. I'm going to take another look at this today and see whether the baffle plate can be transplanted to the new (used) CV. And I'll look at the TSM re: the seal, since Haynes doesn't address it.

If you do the seal in the front diff itself, get the right seal for the side you are working on. On some soobs they are different depending on left or right side.
