Gearbox started whining so though it might be low on oil. Just started to top up the oil in the gearbox and noticed it was pissing straight out the passenger driveshaft as quick as i was pouring it in. Looks like the driveshaft has come away from the gearbox or should it look like that with the gap ? Can anyone explain the pics ? am i looking at getting a new driveshaft or just the seal or something ?
