My '97 Outback (97,000 miles) has apparently worn out the rear diff- clunking in turns- I think it's a limited slip. I replaced the gear lube and friction additive, but that didn't do it. The dealer wants over $900 to fix it. Has anyone done this repair? Am I crazy to attempt it? I've worked on the drive train on my Jeep, but the Subaru AWD system is quite a bit more complex- OK, intimidating.
