You say it's pulling left but I've no idea what wheel bearing you just did. Should I assume left.
You now say a audible wheel bearing sound again. You never told us this before. What does this sound like, oscillating, steady, varying with speed, grinding?
You may have junk bearing kit. That is why Kurt
@cruiseroutfit was recommended to you. He's a tursted vendor here in mud, with only the best products.
You've not stated your year. I looked at one picture you posted from FSM which looks like 2004. Is that what you have?
You've not stated if your rig has any mods, what tires etc.
A lot of this can be covered by a signature listing your rigs particulars. See signature of those trying to help you, it tell what and how set up.
Hub flange nuts will not have anything to do with pull, unless you left off.
Wheel bearing would have to be extremely loose to cause pull this soon after servicing.
Most people don't properly set breakaway preload, leaving wheel bearing loose. What did you set breakaway preload at?
Did you grease axle needle bearing and bushing?
Any chance brake pads are rubbing?
What is condition of front drive shafts?
What is condition of Steering Rack and mounting bushings?
What is condition of TRE's?
What is condition of ball joints?
What is condition of UCA & LCA bushing?
Low tire pressure, variation in tread pattern, alignment will and is most common reasons for pulling.
In 2003 the series 100 Rack and pinion steering was changed to Variable Gear. This takes special adjustment to set up steering. This will certainly cause pulling, if not set up properly. Sorry you'll need to look-up yourself I'm just to tired at the moment.
