Hi everyone I have a 1999 rodeo 4x4. I noticed that while driving esp between 20 to 30 miles an hour. I hear a voom voom voom sound about once ever second. Not noticeable below 20 and over 30 it kinda seems to go away . Now truck drives fine and sound is not effected by applying brakes. Could it be bad u joint ? Wheel bearing ? Now from 1 to ten , ten being high , I would say the sound is a 3 or 4 . Any ideas ?

 

Seems to be a engine problem. Check the basic which is the fuel filter and air filter. Also the header bolts.

 

No not engine cing from wheels tires can't figure out if it's front hubs or axsle

 

The voom voom is like a rubbing sound or like a wheel out of round sound, and only while car is rolling and passed 10 to15 mph and can not hear it over 40
