A while back when I had older BF Goodrich Rugged Trail tires that originally had 63000 km on it on my 2011 Titan Pro-4x, they started to make a 'wub wub wub' noise at all speeds. First, I thought it was a wheel bearing either from the passenger side or drivers side. I took it to local Canadian tire shop and they told me my tires are out to lunch and needed to be replaced and alignment was way off (especially toe angle). Since I knew I needed new tires because they were pretty much bald, I replaced them with brand new BF Goodrich All Terrain KO2 tires and got the alignment done as well. I personally talked to the mechanic and he told me that everything in the suspension is looking tight (including wheel bearings) except that there is a small amount of play in my passenger side CV joint which is normal and he figured it shouldn't be a problem for another 5 years. Ever since I got the alignment corrected and installed the brand new tires, my truck has started to develop the same noise again, but only at speeds between 30 to 60 km/h. The noise is coming from the front end in general no matter if I'm going straight or if the wheels are turned right or left. Also, it makes the noise while I'm coasting/slowing down and it gets louder as I apply the brakes and fade away after the speed reaches less than 30 km/h. I am unsure if this is actually a wheel bearing noise or tire noise since the tires have a pretty heavy duty tread pattern. I have also noticed that when I apply brakes when driving at highway speeds (100 - 120 km/h), the steering wheel vibrates a tiny bit, but not significant, so It could be my front rotors that might be causing the noise I'm guessing. I would like to know an opinion before I can take it to a dealer and get misguided. If you guys have the same problem and have a solution for it, please let me know as this is driving me crazy just thinking about it.
