Never used an angle grinder before but I did last night! Tried the mole grips route on the disc peg only to damage the head of the nut even further! I don't know what was used to tighten it in the past. But anyway, off with it's head! After a bit of jiggery pokey with a borrowed angle grinder (and thankfully only a couple of scores in the disc mounting face!), I finally got the disc off...
...and the old wheel bearing off...
...and the new wheel bearing on!
Very pleased as I wasn't looking forward to the prospect of having to grind off any part of the bearing. But it came off pretty easily after some pretty sharp and heavy pushes on my breaker bar to undo the old nut. I put in plenty of grease as recommended and did up the nut as tightly as I could.
Question - My breaker bar is 66cm long and I put as much pressure on as I could before I couldn't move it any more! I was concious of the bar bending a bit though (is it a case of 'they all do that sir'?)...! Do you think it's worth taking the car to a local garage and giving them a few quid to pull the wheel and brakes off and checking with a proper meaty torque wrench for the 266-294Nm? Or does it sound like I've done it up enough?
rgwm - appreciate the offer - if you do have one please let me know and I'll p.m. you my address and can sort out a few beer tokens via paypal of something... I understand it's not nescessary right away but I would like to fit a new one at some point - probably when I replace all of my brakes in Sept/Oct (hopefully I wont need to repeat this process for those brakes!)
I still have the car up on axle stands. I got the disc, pads/caliper back on but ran out of time. I'll be putting the wheels back on tonight and having a little test run. The disc seems to be clamped a little more tightly than the opposite wheel - I'm hopeful a couple of taps on the pedal will set it back how it was...?
Cheers again for support guys - invaluable this forum
