My LS400, ostensibly a car made for eating up highway miles in comfort, has had a nasty vibration at highway speed that sort of ruins any comfort there might have been. Today I finally ordered the OEM castor arm bushings to remedy that issue. Also ordered: #82 Keihin main jets for the CX500 and new carb boots. Grand total is about $82 for all that. Hopefully it all works out.
