"If at first you don't succeed, try, try again"
Or as my Dad used to say, "You ain't using a big enough hammer!"
I had a go with the angle grinder approach. I wasn't sure it would work as the only discs I have are for stone I think, but I set about the bearing race and it did start to wear away.
So I kept at it until the metal started to get very thin. At the back it's a lot thicker so I just cut a fair bit away. I'd manager to create a "lip" in the race, so whacked it every now and then with a 4lb and chisel. Nothing, so kept grinding.
Then one hit made the race move slightly. A bigger couple of knocks moved it further and started to move it out from the back of the stub axle. Now I could get a chisel down the back and eventually ... off it pinged. There is a hair-line crack through the thinnest part!
Now I see the two holes that another forum member referred to. They are visible from the rear of the hub assembly: one above and one below the stub axle. But they are so small I'm not sure I'd have had anything small enough or strong enough to punch the race off that way. It was pretty solid on the stub axle. The heat from the grinding probably also helped a bit.
Anyway, cleaned up the stub axle, especially at the hub where it was pretty rusty in a couple of places. Then drifted the new hub and bearings on as far as I could. Fitted the hub nut and tightened it up.
Replaced the hub assembly, and then tightened the hub nut as far as I could using the breaker bar and my weight bouncing on the end (I'm around 10 1/2 stone). Stopped when I couldn't get the nut to move any more. Staked it to the stub axle, replaced the end cap and torqued everything up. Refitted the brake disc and caliper, then wheel. Spun the wheel and with fingers resting on the bottom of the spring, felt ... nothing. Smooth as a baby's b*m!
Quick test drive. No rumbles.
Now to order that new tyre tomorrow ... yes, inner edge worn completely away as I first thought it was the disc binding. Brakes needed replacing at the rear, but rumble stayed on after. Moral in the tale there. Jack up the car and rest fingers on the spring. Spin the wheel and feel the damaged bearing cause vibrations!
(I really need two new rears, but funds after Christmas are a little depleted! Especially as
I had to buy the bearing kit and removal tool as well. I'll get the other tyre replaced early next month!)
I'll post pics next week.
