    Default High Speed Acceleration Deep Hum

    Sounds weird, but when I hit the 90 - 110 KMs on the highway, I get this deep humming, there no lack of power for acceleration, there was vibration but thats gone now with a replaced tire rod. Only has the sound when giving it the gas, no I had my UJoints looked at, mechanic says they are dry, but solid.

    Ideas experiences?

    I'd be interested to know too. I have the same issue on my Bronco. Is yours lifted? I'm thinking maybe a driveline.. I don't know though.

    What kind of tires are you running? Aggressive tires are noisy, so it may be them. Grease the u-joints! It only makes the sound on acceleration? Replace the air filter and check all of the air intake system for tightness.

    No lift, 265 70R17 Good Year Silent Armor 10ply Class E Pro Grades

    All new rotors, all new pads, all new shocks, new tire rod took vibration at high speed out, new mc

    I was thinking ujoints but the mechanics said they were solid and tight, i think its ujoints as well, also at high speed it sounds like something right under the truck is trying harder, but no lack of power, no slipping notta

    When I say trying harder it sounds like something is loose, i just cant explain it

    Only other thing I have going on is the rear left wheel squeaks even when not accelerating

    Jesus, this trust sat in a heated garage for a year with no use, when i parked it it didnt have any of these issues lol
