Hi,

"No clearance to insert new stud?"

--> Yes, no clearance. But if you had the experience of replacing these integrated bearing hub assembly, you'll notice that the outer portion (the one with lugnuts) could be detached/separated from the inner portion (the one with ABS ring) without much force. Just pull them apart. Unfortunately this will expose the bearings inside. Careful not to let any dirt gets in. Then take the outer portion of the hub to the machine shop to press the broken lugnut out.

New hub assemblies comes with a plastic tube insert to hold these outer and inner portion together. The plastic insert must be carefully removed before installing the hub onto the front axle stub. I was shocked when the new hub assembly separated while taking it out of the box. I thought I had ruined them. I had to hammer them in together before installing them onto the front axle stub.

Dear Blindboy,

Hope you're well and stay so. A still-serviceable hub can be rescued. Once removed, the ABS toothed-wheel can be removed. Saturate it with a penetrating oil, e.g., PB Blaster, Kroil, etc.. Use a plastic mallet "to walk" the toothed wheel off of the hub. Tap around the edge of the toothed-wheel. Eventually it will start to move.

To keep the bearing balls in place - while removing the toothed-wheel - pack the stub axle opening with tightly-wadded plastic film, from, e.g., a dry-cleaner's bag or a disposable grocery store bag.

Once the toothed-wheel has been removed from the hub, take the hub to a mechanic, who has an arbor press. That tool will easily press-out the sheared bolt stud and press into place a new stud. A replacement stud likely can be had from a Volvo dealer or any aftermarket parts supplier.

Hope this helps.

Yours faithfully,
