My h145 lasted 11months of hard thrashing behind a worked a14. Only replaced it 2 days ago and it still wasn't dead just noisy a hell. When I pulled it out I found that the grub screw had broken allowing the centre pin to float a smash into gears making the horrible noise. I musn't thrash it as hard as some of you guys who seem to kill them in a matter of months, weeks or even days. Hey and im only a youngin. I thought you older blokes didn't kill cars as bad as the young blokes.
