2006 Tundra in my sig.
At 35mph+, you hear "rut rut rut rut rut rut"
By 60mph, it pretty much becomes solid...."ruuuuuuuuuuuu....."
It increases with wheel speed.
It is LOUD in the drivers seat. It is hardly audible in the others. You can feel it in your feet in drivers floor.
It's been doing this for 3-4 years, ever since towing a heavily loaded camper through the appalachians. Brakes overheated, and I later saw grease coming down from the back of the knuckle from the bearing location. You would think now that it would be...., right?
Asked mechanic to replace bearings 3 years ago. He said NO, they aren't bad, no noise on the lift, and at $400, he couldn't do it in good conscience. Suggested tires.
Tires were approaching wear bars, so, OK, 2.5 years ago, I put on new tires, different brand.
SAME SOUND remains. Again, this seems obvious to me.
By last week, with several headaches lately, that sound was really bugging me. Took it back to the shop. Asked them to replace the bearings, front left. They call back - "man, this is an expensive job, and they don't click or show any signs of issue on the lift. are you sure? We think it's the tires, some cupping found."
I tell them it can't be the tires... since it did this with the tires before. "Bearings, go ahead and do it."
They call me back the next day. "We are really sorry, the noise is still there. We recommend rotating the tires (which I just did 2 months ago, no change), or living with it since the tires, while cupped, have good tread - but if it's bothering you, your call."
I go back to a tire I've had before and liked - "put tires on it."
Overall cabin noise is down, but this problem noise persists.
So--- maybe it's not the front - maybe it's being carried from elsewhere and is just showing up there, resonances and all. So I change the diff fluid in the rear. amsoil 75-110 severe gear. Grey fluid comes out, honey fluid goes in. There's about .25 cm^3 of debris on the magnet from 30,000 miles, not bad at all. Again, overall noise level drops more, but the problem noise is still there.
Everything in me says it's a bearing.
There is no differential whine.
OR, is there a collapsed bushing? Strut assy bushings look OK. Frame mounts?
I am out of ideas!
