Was that dog bone knackered in the first place? Also did u get vibrations on idle after fitting polly ones?
the old one dogbone still in good condition, main reason why i change it, course exhaust sometimes on cold engine have noise, looks like touching chassis, i be at AMD but he can`t find anything, so that why i buy dogbone and replace it, and noise gone
another good point now , i feel less play when change the gear
about vibrations can say may a bit more feel vibration on stering wheel on idle , but nothing horrible
