Having used the pictures on the first post of this thread to replace the rear wheel bearings in my Jazz (52/2003 130k+ so excluded from extended warranty) I wanted to post my experience.
I am by no means familiar with the inner workings of a car but this was my opportunity to learn. I bought the basics (torque wrench, trolley jack) from the usual suspects on the highstreet and set off with my mission.
Everything was fine until the point when the old hub "slid off" - did it heck as like! It was stuck fast and stayed so for four hours despite my efforts tapping, hammering, lubricating and generally cursing.
I then had a brain wave which when it worked I couldn't believe I tried earlier. I took the bearing from the passenger side (which came off with no effort) and "piggy-backed" it on to the driver side one using the wheel nuts - a single sharp blow to the piggy-backed hub and the damn thing popped off!
So if you have a similar experience, and are not fortunate enough to have a "wheel hub puller" then give the piggy back method a try - works a treat
Car is running like a dream now - almost road noise from the rear (from a deafening roar before the repair).
Shame it cost me £60 more than taking it to the garage but I now have the knowledge and the tools to embark on similar "simple" repairs so should recoup the costs with the remaining time the car has left (...fingers crossed...)
