Thanks Dave, nice to know these tools work.I have a bearing press tool as described in post 7. It struggled on one side but gear oil on the threads and bolt bearing surfaces got the old bearing off. The new bearings went in fine and the job (while hard work) was really no different to a using a hydraulic press.
I fitted the bearing into the hub carrier, then fitted the (new) hub into the bearing. I got everything from Shop 4 Parts.
