Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
There is not enough room to get the new studs in without separating the wheel bearing a little. You run the risk of damaging the bearing by doing that then pulling it back together though. Hyundai's procedure is to remove the hub, press the stud out and the new one in then install the hub into a new bearing.
You should have plenty of room to get the old stud out if it is broken, if it is just damaged you can cut it off to get it out.
When pulling the new stud into place it is helpful to grind off a third of the flange on the head and that let you leave the bearing in place.
Please let me know how i can help you with this
