Did my swivel bearings and a wheel bearing and the tracking is off. Now I'm getting a droning/whining above 50mph. Defo needs tracked as the steering is off to the left. It's going to be done tomorrow plus the gearbox oil as I popped a shaft out momentarily too. Thought id topped it up so was thinking it's the tracking and the hard PS4 rubber. At least I hope it is. Anyone any experience of PS4 on a car that needs tracked? RS 175 Cup Lux
