Noise after new tire-installation & wheel-alignment

[White Shark]

Hi,

When I am driving around 60-65mph, there is knocking noise coming from the back. It happens only when I tab the gas pedal while driving. I thought wheel lock bolt moving around inside the truck, but not.

Any idea what could be the problem? It just started after getting new tires installed with wheel-alignment yesterday.

Thanks!

First I would make sure the wheels are tight.

Then I would make sure they didn't leave something on the rear suspension loose if they aligned anything back there.

If you are 100% sure it did not make that noise before I wouldnt drive it until I talked to them and found out if they messed with the rear suspension at all.

Well I got both front and rear wheel alignment, so need to contact to the dealer to check the rear suspension. Thanks for your advice!
