Go LSD or stay stock?
My differential pinion bearing is whining at 10+MPH. Took it in and the local shop (great guys, btw) and they quoted me a used diff replacement ("low mileage", 6mo warranty) diff "green-seal" improvement, boot seal replacement, general cleanup, fluid replacement, etc for about $985 (The diff was about $385, other parts about $150).
Asked if I brought in a new LSD and he quoted me 4 hours (~$100). thinking about $1700-2000k for the LSD diff...
So $2100-2400 for the LSD or $1000 for used, stock???
should I bite the bullet? Is the LSD that much of an improvement? what would you guys do?
