2006 Infiniti M45 Questions & Answers
What does a damaged wheel baring sound like
A bad wheel bearing noise will normally increase or roar loader with car speed but depends on how bad it is. If you turn momentary to the left or right while driving down the road say above 30 mph, the noise will change pitch either gettin loader or quieter. Locating the correct bearing to change can be tricky because sometimes it may sound like the left bearing but it can be the right. The best thing to do is to jack the car up on jackstands and get the wheels spinning and while spinning prob the hub area on the back side of the wheel with a mechanics stethoscope to pick up the sound. Placing the plastic end of a long screw driver against the ear while probing the inner hub with the other end works equally well for locating bearing noise. Compare the noise heard while spinning and the noisy one is the bad bearing. Do not spin the wheels fast while on jack stands or it could cause damage to the halfshafts (cv joints). Spinning the back wheels with be hard to do since there is no poweer to them. If they are bad enough, they will still make noise while someone is spinning them by hand. Most shops have a device for spinning the wheels.
Catalytic converter & check egine light
You didnt say what country or state you are from. If you are from the US removing the cats will cause your to fail safety and emissions inspections due to missing components ie no catalyctic converter. The cats dont have anything to do with exhaust noise. They are there to capture bad emissions. What dealer did you take it to? A reputable dealer would not have told you straight pipes would solve the problem.
What cause the SLIP light
Any time there is diffrence in the rotation of the wheels or if the tires are of diffrent size/speed rating or if the tire pressure is not same in all tires the slip light will come on as the ECM thinks that the vehicle is sliping.
How many quarts of oil
It says 5 quarts with filter change and it also recommends to use 5w-30. I would double check as you fill as well as after you run the car for a minute. I hope this helps and good luck.
