There are two ways to move a fastener that has bonded itself in place, and only one of them works. Pulling steadily on a long bar puts a rising load into everything at once, and what usually gives first is the weakest part, which is the pattern in the nut or occasionally the stud itself. A sharp impact does something different. It delivers a very short, very high load that cracks the bond between the two seized surfaces without ever getting the chance to twist anything to destruction.
That is why the right tool here is percussive rather than muscular, and why leaning harder on a brace bar in a lay-by is the worst available plan. Applied properly the shock breaks the corrosion, the nut suddenly becomes an ordinary nut, and it winds off. Everything then goes back on with a torque wrench set to your manufacturer's figure so that whoever takes the wheel off next has an ordinary morning.
A used car with no locking key is more common than the trade admits. If it has already gone, we can come out to Croyland or wherever the car is parked, extract the nuts with the right tools and fit a standard or replacement set so the car is straightforward from then on. We are out on the A45 at 2am and in Queensway at 2pm. The Finedon phone and the Wilby phone ring the same fitter, any hour.

The A45 is not a road on which to be exploring whether a wheel nut will move, and Wellingborough's estates spread a long way from anywhere with a ramp. Both facts point the same way. The tools come to the car, the nut comes off where it is standing, and any tyre work carries straight on afterwards rather than becoming a second appointment.
A steady pull loads the nut, the stud and the pattern all together, and something eventually yields. It is very rarely the corrosion. Stop before the pattern goes, because a rounded nut takes longer than a stuck one.
Once the bond cracks there is usually no resistance left at all, which surprises people who have been fighting it for an hour. The seizure was never about how tight it was done up.
A tyre that went down overnight and a wheel that will not come off is the classic early morning call here. The car does not need to move, and the whole job is finished where it stands.
Because a steady pull is the wrong kind of load for a corroded joint. It stresses everything evenly and the pattern in the nut usually surrenders before the corrosion does.
We would not recommend it. Applied in the wrong place it damages the stud or the hub, and the difference between a useful impact and a destructive one is mostly experience.
Occasionally one does, on a stud that was already stretched or corroded through. We will tell you straight away if that happens rather than quietly refitting and saying nothing.
Yes, we attend the distribution parks and yards off the A509 and A4500 regularly, and we will come to the gate or any safe spot on site.
Yes, a plain one of the correct thread and seat, torqued properly. Say on the phone if you want the whole set of locking nuts replaced and we will bring enough.
