Default Wheel bearing/front hub assembly

I'm not sure if this is a prime suspect or it is something also but when I driving the car and have my left foot rested on the floor I can feel some periodic knocking which is gets faster with a speed. My car also pulls to the left when moving which I dont remember happening before. How hard is to replace the whole hub assembly? I can pick one from RockAuto for about $110 each. Do I need to do both sides at the same time or just the bad one enough. Also, there is about 10 different ones I can get in a price range from $98 up to $270 for AC Delco one, which one to choose? Thanks.

The typical symptom would be a humming that correlates to speed.

A knocking may be a CV joint on the axle or some other thing.

I have had the same thing and found it to be the tie rods. Inner and outer were replaced on my 95 pass. side. That did the trick for the knocking on the floor for me. Keep in mind there was very little play but the knocking was horrible.

Sway LInks Anyone? Stick yer head under the front end and look to see if the sway bar is still tied in on each side or if the "pin" is broken. May account for the slight pull and is the cheapest place to start.

Clanking or jingling...I forget what that thread was titled..but it was perfect for link noises.

Well, now it makes it even harder. If the hub assembly is out of suspicion than I would lean more towards the tie rods. Sway bar links were replaced just this summer, one of them snapped because they were really rusty and a metal was very stressed. I replaced both of them and steering feel improved quite a bit, now its feels kind of wobbley again, but a little different compare to the broken sway bar link feel. I can for sure tell something snaps or clunks when you backing up and making a left turn (left if you look forward) simultaneously. It is not a CV joint, because it never clunks in any other forward turns no matter how hard I turn. And the CV boots in good condition with no cracks. I guss I might have to jack up the car and take a wheel off to diagnose it any further.
May be in the first post I didnt described simptomps correctly, its more of the ticking I can feel with the left foot than cluncking, its not loud and can be barelly noticed, ticking however doesnt have a very linear pattern, this is very confusing.
