Stud replacement

What is your question?

Took my truck for wheel balancing and they told me that there is 1 wheel lug nut that is broke. Don’t know how it happen and when. Mechanic said it’ll cost me $700 to replace them. Can’t seem to find anywhere on how to fix them myself. Anyone has same experience and how it was dealt? Thanks

How long has your 2007 GMC Canyon had this problem?

Don’t know.
