As I have some extra long day trips coming up, I wanted to take today to fix the rumbling sound in the truck.

I presumed it was a bearing, I am fairly used to the sound. So, since I have a spare, I swapped it. That was about noon.

it’s sort of pathetic that I can do the whole job in under an hour. A testament to how often I’ve done it, no doubt.

Same noise.

I have free lifetime rotation and balance on the truck tires so I had that done, the tires were a bit out of balance, same noise.

I change the brakes. Same noise
I changed the bearing BACK. Same noise. I changed the bearing on the OTHER SIDE, same noise. I topped off the fluid in the differential. Same noise.

I’m, laying under the front of the truck with my flashlight, looking for anything that could be making the noise. I notice a weird wear line on the iner sidewall of the left front. They only rotate radials front to back, so this had to have come off the back. So i get on my tortured knees and crawl around to the back, and the bracket holding the Ebrake cable in place has come loose and it’s rubbing against the tire. I wrap some wire ties around it, and the noise is gone.

Damn. An all day goatrroping I could have fixed in five minutes with a piece of string. Sonofabitch. Well, live and learn.
