if your gonna do it yourself without the cone make sure you but a new driveshaft circlip, DO NOT USE THE OLD ONE!! i made the mistake on my primera of tryin to use the old one but it came loose, the driveshaft loosened from the hub and i lost all drive, was on my way back from airport and had to stack the car onto a roundabout, and fuked my bumper cos i didnt see a 2ft pothole behind the kerb.
the driveshaft nut shouldnt be too bad but make sure you have a 32 mm socket, n your 'supposed' to buy a new nut as well.
but for what some back lane garages charge i would just get someone else to do it, watch him do it then you know for next time.
ps, dont use the zip ones, ive used a few of these and they just dont last
