Gears & Axles - Newbie HELP!!

Lately I've been getting a differential grease smell coming from my car (when it gets hot) and a click noise from the rear passenger side (shaft) when I let go off the gas pedal or when I stop/go.

I also checked the rear passenger side to see and there's grease from the inside of my rim...broken axle seal?

Thank u in advanced!

The click noise went away after re-filling the differential with its appropriate fluid.

But that doesn't solve the axle leak of course. I've noticed autoparts don't seem to carry that axle seal replacement. Is this something to be ordered online and if so, anyone know where I can find this part?

its good insurance to replace the axle bearing while your in changing the seal.
in a lot of cases the bearing has worn and let the axle push on the seal..(leak, leak) , something to think about when you start to work on it.

oh yeah i bought my axle seals and bearings at the local orielly auto parts.

save time and to it all at once they are everywhere and for very cheap and not time consuming to that's a plus as well.

Also at O'reillys or Autozone they lend tools and you're going to need a 3 jaw puller with slide hammer and a seal/bearing driver kit. These tools will make the job much easier.
