I have used king's several times now and the thoroughness of their problem diagnosis second none. I recently brought in my Subaru Outback that another shop (in San Diego) had told me needed the rear differential replaced/rebuilt. After moving to Fort Collins I brought it to King's to get a second opinion to see if they came to the same conclusion. After about 4 hours even with King's being short handed that day, in true King's fashion, I received a super detailed report diagnosing the issue as both rear wheel assemblies (ball bearing). They could not confirm that the rear diff does or doesn't need to be rebuilt but we'll see how things ride after the assemblies are replaced. Doing the wheel assemblies myself this weekend $100 in parts + 4 hours of labor vs $1500 in rear diff replaced is a HUGE win for me. Thanks again King's!
