Well, changed the offside front. Bearing was worn. New Meyle bearing fitted, 19mm hex drive, nuts torque and managed about another 100 degs rotation. Went for a spin, noise still there. Ears deceiving me.
Sod it. Think I need to change them all.
During the course of changing all the bearings it was found to be the nearside front. I was convinced it was the rear!
And smug points go to MJ. When I first messaged her about the noise issue she said that the front nearside bearings are the first to go, I was convinced otherwise. Note to self - don't bet against MJ
