    Just finished replacing OEM axles and installing aftermarket UCAs. Fairly simple, but a couple points to take note of. When doing a "two-for" like this I suggest doing one side at a time to avoid a minor snafu. Jacking up one side at a time will help keep front Dif fluid seepage to a minimum. When you jack up symmetrically you will loose some from Dif fluid, up to a cup and a half. Regardless of which side you start on, having that side elevated slightly will minimize the amount of Dif fluid that seeps out when you pull the axle out and stuff the new one in. I suggest you tackle the drivers side first, it's by far the most time consuming of the two. The second point is to be careful on the axle nut cotter pin covers, they don't always fit over the aftermarket nuts, even the ones supplied by the aftermarket venders. You have to make sure the cotter pin finds purchase before pounding the dust cover back on even though you torqued it to 203 ft/lbs.
