Replacing inner seals is pretty straight forward. Just have to pull the carrier, Which might seem scary but there is no setup of gears or anything with just pulling the carrier, just plop out the carrier and then replace the seals and plop the carrier back in.
You guys talked me into it! Going for the axle sway and inner seal *inspection* HAHA. Ordered some new seals just in case. Wish me luck! Axles will arrive tomorrow.
Last resort you can rent one from the auto part store, and the best is that you get all the money back when you return it!
