I have a 2010 Toyota Tacoma TRD PreRunner 2WD with just under 24k miles. I have taken it in precisely at 5k increments for checkup, routine maintenance. Everything has been fine, but I have had the following done:
* Bilstein 5100 shocks put on (all 4) and alignment done by Toyota just 3 days later (this was about 1000 miles ago)
* TSB Rear Leaf Springs
Over the last few days I have noticed a low sounding humming noise that is actually kind to hear, but I can hear it. Today on my way home I decided to try some things out. At 60mph with cruise control set, it doesn't stop. If I start going down a slope and the gas is let off a bit, it starts to go away and everything sounds quiet and smooth. When I let off the gas, the sound starts to go away. When I put the gas on at above 55mph, I can feel/hear it. I say I can feel it, but I am not sure...the steering wheel feels like I can feel it, but this just be me THINKING I am feeling it.
I have tried to pinpoint where the sound it coming from and I know its the right side, I think the front, but I am not 100% sure.
Does anyone have any suggestions? The tires have been properly rotated every 5k miles and only have 24k miles on them. Like I said, I changed my shocks about 1000 miles ago, 3 days later getting a Toyota dealership alignment done.
I really hope I can nail this down because my TSB'ed blower motor just came in and plan to take it in for that soon, would like to get this addressed as well.
