Noise in driver side axle
It's not that bad. There are a few threads describing in detail how to do it. I'm waiting for my steaks to cook, so I'll give you a quick run down.
Take off the caliper, caliper bracket, rotor, axle nut, upper ball joint nut, tie rod nut, and hub. Separate the upper ball joint and tie rod. Pull the steering knuckle towards you and you should have room to pull the axle out of iwe actuator. Replace the actuator, then reinstall in reverse.
The first side may take you an hour or two, but the second side will go a lot quicker.
