💡 What causes excessive drivetrain shake in older pickup trucks and why does replacing the center mount fix it?
Worn rubber isolators and loose pillow block brackets create harsh harmonic resonance that travels right up into the floor pan. Swapping out a busted bearing assembly is a handy job that locks everything back to factory alignment.
- Verify the intermediate shaft play by wiggling the propeller joint while the tailshaft spins free and idle
- Torque the channel strap bolts to factory pound foot specs so the rubber bushing compresses evenly without binding
- Inspect the U joint caps and carrier bearing sleeve for scoring that accelerates wear on mating components
