Drowning and vibration

[Milex]

Hi everyone, and a happy new year to all, I have been getting a load drown and vibration in the front end of my rx300 , it came in at 45 and got worst upto 60 , I was thinking all sorts worst case scenarios, final drive , engine mounts etc . 

Then I thought I’d better get some of the advisories done from last mot, so off I went and ordered up lower ball joints, inner outer track rods and rack ends discs and pads ,after fitting the ballpoints took it out for a spin and hey presto no more drowning and vibration , just a slight wheel bearing grumble on turning left , so all I can think is that the joint was a lot worse than it was and was amplifying the grumbling wheel bearing
