In 2wd problem starts at 10mph w foot on gas. When I take foot off gas or put into 4wd the problem goes away. Sounds like I am driving on rumble strips on the side of the highway. I have had this 08 suburban in the shop 5 times this year.
Where does the lifter sound come from on a Chevy Silverado?
You can hear lifter click best around the top of the engine, and isolate the noise with a stethoscope against the valve cover. It will occur at idle and increases as you rev the engine, continuing even when the engine is warm. Valve lifter noise is detrimental and should be addressed quickly.
