Been battling a shaking steering wheel under braking for awhile. Most of the time it is minor, but sometimes it gets worse. Already replaced all four calipers as the front passenger side had sticky pistons and pulled hard to one side under braking. Still have a shaking steering wheel some of the time, so moved onto the discs or rotors I've had in the corner for awhile. Was also worried it might be a loosening wheel bearing, so dug in while the weather was still nice and had some time.
One drive flange was RTV'd while the other had an OEM gasket. Found out my lock washers have been abused and re-used many times by prior mechanics. Both of the tangs on the thrust washer were pretty beat up too, and have some noticable gouging I can feel on the faces. Lock nuts have the usual cuts and dings but nothing terrible so going to reuse both sets. Local dealer doesn't have any of this is stock but will have it ready by 8am tomorrow. Should have pre-ordered these just to have on hand but didn't really plan this right.

Haven't done this job in a 20+ years, so help me out:
Should the thrust washer be able to rotate in the spindle threads when torquing the inner lock nut to 43ft lbs?
Should the lock washer be able to rotate when torquing the outer lock nut?
I think the answer is NO to both, so hence ordering all new stuff. The inner tabs on my lock washer and thrust washer hardly engage the channel in the spindle, allowing these to spin/rotate when applying torque. But tomorrow when I got to button all this up, I want to be sure I'm doing it right.
Also wasn't expecting to find Timken bearings. With some discoloration on the inner surface of both. Nothing I can feel with a fingernail, but wondering if this is something to worry about or possible reasons for this.

Spindles seem OK. No wear that I can feel with a fingernail
