when i pull off it feels like the wheels are locked and suddenly free off [its not the brakes ive checked them],i've jacked the car up and spun each front wheel and they both stop and you have to give them a yank to make them move again which leads me to beleive the diff or gearbox has problems,any ideas please,car is a 02plate TDCI Estate,oh yeah ive stopped driving it just in case......
