Vibration or wobble diagnostic

[dagger]

Alright so as of late my car has gotten a worse and worse vibration or wobble. It only seems to happen at low speeds and gets worse with more of a load, either that be more weight in the car or more throttle. At higher speeds (40mph+) you can't feel it at all. Now I pulled my passenger side axle (the side I believe the wobble/vibration to be coming from), wheel bearing and such and a few parts I had questions on. Lucky for all of us I have videos and a few pictures.

Ok two videos, first is the wheel bearing. The sounds heard in the video are louder than in real life which is why I'm glad you'll be able to hear them.

Wheel bearing:


Axle (I was twisting the axle to get the sound to happen):


Now this is the outter end of the axle and I just saw the blueish tint to the metal and didn't know if this was normal?


While I was here I saw my lower ball joint, looks like hell....

Well I ended up fixing the issue, not sure which part fixed it but new axle, wheel bearing, and lower ball joint and its all good now. We'll see how well it holds up ha ha ha. Biggest pain was the lower ball joint, I had a grinder and air hammer, didn't do jack. Drill through with a smaller drill then follow through halfway or 3/4 with larger drill. I did not go all the way through because it left something for me to use the air hammer against and knocked them out easier.

The blue on the axle is from the heat treating process, judging by the video on the wheel bearing, it did not sound good, should be smooth and quiet, and I wish the factory would have just bolted the lower ball joint into the a-arm in the first place.
Your issue was probably a combination of all the parts you replaced, with the axle
probably being the highest contributor to the "wobble"

Thats what I was thinking. At first I wasn't going to do the lower ball joint because I didn't want to deal with it but I stopped being lazy and got the $30 part. lol.

Also the blue ring I saw on the other one when I got it, figured it was normal. Just know that nothing should be heating up that much.
