Talking to Mark at EB Motorsport this morning about new lightweight bumpers for impact-bumper 911s, his Porsche 911 GT3 came up in conversation. The car has just been back to Porsche for the GT3 rear hub recall.

Porsche 911 997 GT3 models with centre lock wheels built between February 2009 and April 2010 were recently recalled for an issue with the rear wheel hubs and bearings. Transport authority notices note that “in rare circumstances, the wheel hubs and wheel bearings on the rear axle may break. If the rear wheel hubs and bearings break, the driver may lose control of the vehicle and create a hazard to the driver and other road users.”

Porsche representatives have allegedly told other mags that hubs and bearings “don’t break” and are being replaced “to standardise the revision intervals”. But owners discussing this in a Rennlist thread note that Porsche Cars NA has been telling owners not to drive their cars until the replacement has been carried out.

A number of owners on GT3 forums have shared how their hubs did break, causing their cars to go out of control. Something else to check if you’re in the GT3 market and another big reason to buy from a Porsche 911 GT3 specialist. This video below shows what happened when one owner’s hub gave out at speed on the Nurburgring. Much harder treatment than the majority of owners will ever give their hubs, but still pretty scary when you know what is coming!
