Second day back at work after a fortnight on the west coast, and I heard a 'twang-crack' noise leaving the car park. I've parked it up and taken a pool car, but I assume it's a rear spring. Probably sheared an inch off it, although I haven't had a proper investigation - before I go ordering parts. It's a little lower on one side at the rear. The rear springs were changed prior to an MOT back in September 2009 at 95k. Now at 140k three years later. Incidentally we were loaded to the gunwales with wife, kids, luggage and hauling a boat last week. Probably par for the course. Are main dealer springs the best, or worth going for after-market alternatives. And before anyone says they have to be changed in pairs - I'm seriously skint, so I'm planning to just do the damaged side. Could be false economy, but needs must. Anything else to watch out for. I have spring compressors and have done springs on the front, but never the rear... and rear springs on my wife's A2 doesn't count which I've changed before.
