Check for worn bushings on control arms, shocks, links etc. Hoping it is suspension related. Have you crawled under for a look while someone flexes the suspension? Can you replicate the noise when parked.The Pilot has been driving me absolutely crazy with the rear suspension clunking noise
The noise SEEMS to be coming from passenger side rear
I've taken out the coil springs, replaced coil spring seats with new OEM pieces, replaced sway bar links, retightened rear bumpstops, double and triplechecked that the coil springs are installed in the correct position
Rear ball joints do NOT have any play, and nothing seems to be loose back there
BUT the clunking sound is still happening on every bump in the road.
It even seems to have gotten slightly worse! ?
Don't know how to describe the sound. It clunks like metal on metal contact
