If your wheels are true and balanced, did you over/under tighten the driveshaft capture nut ?

The brearing has four bolts holding it in place, are these all tight and were the mounting faces clean ?

UPDATE ......
Replaced the wheel bearing today with a new unit , and glad to report the "wobble" has gone ,
and the smile has returned to my face

The old unit (Timken) was found to be at fault, running slightly out of true, whatever that means ?
To be fair the original supplier exchanged it without quibble .

A big thanks to you all for your advice
