yes the big axle NUT is what I meant. The reason an impact gun is suggested quite often is because when you put the hub back in the two bearing races could not be seated 100% against each other, they can twist a bit, bind, the hub is trying to push the inner one out etc.... and using a long breaker bar does not always bring them together, where as an impact will vibrate everything together nice and tight. If you go back many pages I have suggested to people using a breaker bar to take your car for a couple hundred yards and re-check the bolt, this is because the first initial drive will cause the vibration needed to settle things together, and then you tighten again.Bolt? In a mk4, the end of the axle/half shaft threaded and a nut is torqued onto the end. There's also no need to use an impact gun, a long breaker bar is sufficient to torque the crap out of the nut.
I had a growling noise from my front right wheel and some steering wonkiness. Discovered that the axle nut had come slightly loose. 30mm/12 point socket on a 2' breaker bar got it tight again.
Lots of people just torque to x foot lbs as needed and do not think if this...
