tl;dr: No. An impact wrench isn't a cure-all. The mechanic explained that sometimes lug nuts are much over torque because all shops use impact gun to tighten them. That does not cause any problem as long as they are opened using an impact wrench. Well, that's not quite true. Over-torque is bad in and of itself. At a very high level, it damages ...

Unfortunately (or maybe fortunately, depending on your viewpoint), that is not a broken lug nut, but the nut which is formed into the plastic hub cap. Take the hub cap off and you'll see the lug nuts. If you notice, there are seven lugs on the hub cap. When you take that off, there will be eight lugs on the wheel itself. This is a standard hub cap for the ...

I'm pretty sure the wheels will not fit. If my research is correct, Nissan's use a 5x114.3 bolt pattern, while the Jetta uses 5x112. Not knowing which vehicle the Nissan rim came off of does not help much. Two other things you need to consider besides the bolt pattern is the offset of the wheel (how it is oriented in regards to the hub mounting point - ...

I can see where your mechanic is coming from. The reason being that, although like Steve Cross notes, the impact wrench applies a lot of force suddenly, it applies the force in an evenly rotational direction. ANY wiggle in the socket (Which there will always be or you wouldn't be able to get it on the nut) and the breaker bar will be putting lateral force ...

Unbalance tires maybe one of the reason. You may want to go to the shop and have its alignment checked. If they are new, you may have a free check up where you purchased them which i have done before.

In order to fit a different size or type of wheel to a car, four things need to be compatible: Pitch Circle Diameter (PCD) - this is the number and distance between the nuts/studs, e.g. 4x100 (4 studs, 100mm diameter). This needs to be the same for both old and new wheels. Centre bore diameter - the size of the hole in the middle of the wheel. If it's too ...

It's already well answered here but typically you torque items "under load". Since torque values specify a clamping force you want to be sure that the conditions of the part are most like the "real world" when you set the torque. When I do tires I center the tire and snug down all lugs before putting load back on the suspension and then torquing the lugs. ...
