and you have the clatter from the rear most notable at low speed over bumps and potholes, just replace #8 and the odds are Very good this will fix your problem. If you have access to a press, I have heard the inserts are hard to find, but out there, for big savings.
Or if no press available or you don't want the hassle, you can get the Vertex polyurethane rebuilds for a virtually permanent replacement - that costs less than oem and tightens the suspension a bit with No appreciable added noise.
This is very doable as a DIY, but getting access to the forward bolt with a torque wrench is somewhat difficult.
If this is all you swap out, and you don't face them inside-out
, you shouldn't have to get an alignment unless you already needed one.
