just a quick question

well on my other topic i basically said something with the car because it kept on knocking when turning left all the joints are pritty new and no rubbers are broken, drive shaft is 2 months old and in good condition, so i got it up in the air and started looking round, after taking every single thing off strut on the drivers side put it all back together greased and cleaned i started on the passengers side, first thing i knoticed the wheel was really really loose my thought was bearing strait away (tho it was under 4 weeks ago i fitted a new one) the driveshaft can move say 3/4mm side to side from gearbox to bearing and the bearing casing can move, can this be the reason my car is knocking all the time while turning left? since the driveshaft is like 2 months old should i just replace the bearing?
