I have a 2004 infiniti fx35 awd. I bought it with 77,100 miles. i replaced the rotors and brake pads with OEM hardware the day i got it along with every fluid flush in the book sept for rear dif. I heard a rattle noise from driver rear and thought it was the aftermarket hardware for the brakes shifting around, so i replaced everything with OEM. expensive and didnt fix it. The rattle happens only when i go over little bumps at 5-40mph anything faster u really dont hear it and its only with the window down u hear it. I checked almost everything the only thing i can think of is that the i need to adjust the starwheel for the brakepads....?any thoughts on this or heard of anything like this please let me know. Now the other issue is on a cold startup there is a pop noise from the front and can be felt through the brake pedal, happens 9 times outta 10 kinda thing, after its been turned on and i turn it off then back on doesnt happen only on the initial startup.????any ideas. ? thank you
