Re: Rear end noise
depends on the noise. clunk, whine, squeak, groan, whirring, clicking etc etc. list goes on and on. could be brakes, u-joints, bushings, bearings, posi, gears. not being a smartass, but its impossible to guess with what you've described.
only turning left and right helps, try to drive it a bit more and do a few things when its making the noise. at really slow speeds; go to a large open parking lot and gently apply the brakes as your turning. if you can, do this while braking with your left foot. Imagine trying to just make the pads touch without actually slowing the car down. does the noise change? do the same and accellerate slightly. any difference? does it do it in reverse? as we rule out some things; we can have you drive it differently and figure it out.
But to be honest, its probably easier to go to one of the bigger chains that offer free suspension evals (sears, belle tire, etc). have them rule out suspension issues, u-joints and axle play as the cause. Once they do that, and dont find the problem; your in for a rear cover removal and inspection at the minimum. Or a rearend rebuild/replace on the $$$ end. from that point, you can go cheap takeout swap at home to a big$ aftermarket rear. the choice is yours.

BTW, auto or manual trans?

Re: Rear end noise
These 10 bolts have 2 common bearing failures. The outer pinion bearing fails due to housing flex (leaking pinion seal is a good indicator of pinion bearing problems). And the axle bearings often fail due to low fluid levels. It sounds like you have an axle bearing that is bad. You will need to replace the axle seal, bearing, and axle on the affected side. Or you could save a little money by going with an axle saver bearing that allows you to retain the stock axle shaft.
