Ok. Thanks. I was looking to upgrade the rear end, but I'd still like to keep my 4.11. Seems that most 1.8's are Geared much taller. The dollars all start to add up if you do it right. I was considering, perhaps hardened gears? I mean, I'd end up buying gears and an LSD For the 1.8 anyway... thoughts?

That would be nice. I passed up a 1.8 diff carrier stub shafts and axels for $275 Shipped a few weeks ago. Now that I'm looking, I'm kicking myself.... That was a good deal. Just have to keep looking. Now that I know a 4.3 is what I need, I'll just have be ready when one pops up. Are these fairly common? How would you know by looking at it? As of now, I'd have to take thier word for it. Thanks.

i recently noticed a "woo-woo-woo..." sound that happened when my car was rolling in neutral and was amplified when engine braking in gear. The sound disappeared however when accelerating in gear which was strange, never the less i jacked my car up and found an oil leak permeating from where the pinion seal was on the diff. I think the reasoning the sound got worse is because of the amount of oil that leaked over time.
I took it to a mechanic i trust today and he told me that my car has the 1.6 LSD (the seller must have provided a fake copy of a reciept for a 1.8NB LSD, an enticing factor when i bought it a couple of weeks ago).
The mechanic also told me (without looking into the diff) that with the amount its going to cost in labor that i may as well buy a 4.1 diff and axles used in the 1.8 instead of replacing the seals on my current 1.6 LSD. i like the LSD, especially fun in the wet but my car does have a 1996 1.8L engine in it.
is the mild power difference between the engines enough to warrant the spending on a new diff and axles when i can simply replace the seals for $130 + 3ish hours of labour if the current gears in the diff are in good condition?
this is the closest thread i could find to match my question, if someone finds another thread with my predicament id be happy to read it if linked below.

I'm not very good at distinguishing if it is a 1.6 or 1.8 diff however they said it was a 1.6 diff because it was smaller than the 1.8. I thought a model number imprinted on the diff would be a better determinant than the size however i didnt look into it because i was at work when the mechanic called. I thought the size of the diff would be a better indication to the gearing inside but im mechanically noob so i just took their word for it.
is there a tell i should look out for?

The 1.6 VLSD is easily identified externally, as the stub axles have a unique flange where they mate with the CV joints:

The 1.6 open diff has star-shaped stub axle flanges on both sides:

The stub axles on the 1.8 diff (open or Torsen) don't have the extra four ****:
