Rear end question

I'm just running around town it it, by myself, and it's whining about what it was when I got it. (not much, but u can hear it)

Anyone have a short list of bolt in rears? I don't wanna go through the r&p expense if I can replace the whole thing for less time and effort.

I've looked at Ford 9" but that requires cutting, welding and axle re spline. Way too much time, and yall all know how crazy the 8.75" stuff is, if u can find one its gonna run 2 grand to get going.

This car is just a toy, i'm not putting 20 grand in a Barracuda here. Hell I gotta pay Barracuda prices for a Valiant!

It's a bone stock 99 Durango engine with 44k miles on it, and i'm not looking to upgrade that till it breaks. Just love to drive it at all right now!
