I have a 2006 Mustang GT and just had the left rear wheel bearing replaced. They also rotated and aligned the tires. Since I got it back if you are at a dead stop and start off turning either right or left, the back wheels seem like they aren't turning at first and it sort of skids and jerks the car until you get going. What could this be?
Could be a problem inside the rear end, or an issue with the bearing that was just installed. I'd definitely take it back to the repair shop and tell them you have an issue. They should take care of it for free since it's obviously something they did.
