You wont hear much of a sound, but more of a vibration at certain speeds. I recently installed a set of tires on my truck and because of an inbalance, around 70mph the truck would start to shake. Once I had it corrected it was smooth sailing.
why is my 1991 Mazda truck surging at higher speeds
It is called the venturi effect. The air pressure between the car and the truck reduces due to the relative speeds
Stand on the front and rear bumbers, and bounce the truck up and down then jump off. the truck should bounce once are twice. If it bounces more then that, replace shocks.
The blower motor speed resister is burned out.
Start by calling an insurance agent and find out what liability coverage for a bounce house business would cost. Once you pick yourself up off the floor, you need: a business license some commercial-grade inflatables--bounce house, water slide, whatever. These cost about a thousand dollars apiece. a logo and a business phone a website a wrapped truck so people know you're in this business, and a wrapped trailer to carry the inflatables
when air is pushed forward, is has less pressure to the sides then in front, causing a vacuum on either side. when the truck speeds by, it causes this affect on a descent sized scale, large enough to pull your car.
More then likely you shocks are bad
About an hour at highway speeds.
A Penske Truck leasing allows you to purchase a transport truck from the penske company for a certain amount of time. This form of payment requires you to return the truck after a certain amount of time.

Vibration, no but excessive bounce or wheel hop, yes.
