When i turn, sometimes the rear end makes an odd moaning sound. It sounds like it's coming from the axle.

Is this the diffrential going out?

I had someone install new rear axle wheel bearings, but now that i think of it, im not sure if they packed them with grease or not, when they installed them. Could it be this too maybe?

Thanks!

 

Most likely you need some posi additive in your rear end fluid.

Axle bearings only need grease for assembly and until some of the rear end grease makes its way out there. It's not like front wheel bearings where they're dry except for what you pack them with. That's not the cause of your sound.

Uh, so how would i do that? is there a bolt i undo or something, and pop a funnel in and fill it with fluid? Sorry, im really not familiar with the rear-end at all.

There's a plug in it about halfway up, take it out and pour the fluid in. An easy way to get it in is a squirt type oil can like you can get at the hardware store.
