Why this part
A new housing costs more and solves less — if the bore is sound, the wear is internal. This kit addresses exactly that, putting fresh load-bearing and articulation components back where the degradation happens. Correct fitment requires a 1.438-inch QA1 housing, so measure before ordering.
