2007 S40 AWD.
I have some damaged front and rear wheel studs. Are these replaceable the way they are on other cars by knocking them out and pulling new ones in?

 

I broke a front wheel stud on my 2005 recently. I searched a while but could only find complete wheel hubs with the studs installed. So I decided to remove the broken stud and see what I could make work. It turns out that the design of the wheel hub blocks the stud from being removed completely. I had to use an angle grinder to make a flat spot on the head of the stud in order to get enough space to remove it. Only a bit of a pain, but the broken stud came out.

Now we all know there are many many different types of studs. Certainly something from the parts store would fit? Well yes it does. I have a 1986 Pontiac Fiero as a project car. I purchased longer studs for a brake upgrade. These have a small head which allow them to just slip past the wheel hub and into the flange. They fit and have the same thread pattern. Dorman part number 610-323. Its the one on the left.

 

How did you break the old stud loose. Hammer?

 

Air hammer. Vibrates them out in seconds. Use the pointy tool on the end of the stud.
