The other night when I got home from work I had noticed a few small oil spots where I park. A quick wipe of the finger and smell told me it was transmission oil. I finally got underneath it today to assess the situation and realized the half shaft bearing is completely toast and allowing the axle to slide in and out of the transmission. I know the bearing is pressed on the axle and I will need to replace the whole axle in its entirety unfortunately. But do I need to replace the bearing housing that wraps around it and bolts to the block as well? What OEM parts site should I order from to save me a few bucks? I also can't seem to find any posts or videos with any sort of insight on how to do this job, or removing an axle in general. I'm way out of warranty so this ones gonna be on me so any kindof guidance would be greatly appreciated! Car is a 2013 ST with 70k miles. Thanks guys!
