Sometimes man... Sometimes
Are you asking me? I have a sealed hub I can not get to the inner and outer race the wheel seal or any of it if you have a serviceable hub like the 2wd with rear wheel abs then you can just do the inner,outer races and the wheel seal and call it a day for 40 bucks or so a side
I'll also second the cheap hub assemblies are, well, cheap. My brother-in-law had to replace one on his Blazer, after telling him to spend a little extra cash on the better one, he went and bought a cheap one. It went bad in about 2 weeks. He proceeded to DO IT AGAIN with the cheap one. Went bad in about 3 weeks. He FINALLY listened to me and got a National one I believe and that was about a year ago.
