Suspension gurus what do you think of these readings?

[Fred@BTM]

you can spin rear discs and hear no noise but when driving the bearing makes a noise, the rear has about 400kg of load on it, that can't be replicated with the wheels in the air

Cheers fred, can't hear any bearing noise when driving but will put some new disks on. What are your thought on the slight pull to left given the readings?
