So up at 6am to nip to my mates garage before they start work to put these on! Mine were original, 80kmiles and way past their best. These have been a vast improvement, it's like having a new gear box now the lump isn't wallowing about?!? I'd recommend heavily lubing the 18mm nuts on the underside prior to doing it and whilst laid on your back it's possible a ramp is going to make the job a doddle. Forty minutes and they were done
