2010 CX-9 GT Front Driver's side wheel bounces when accelerating up a hill

Hi Everyone. Newbie to the forums. Here are the details: I'm from Seattle, WA, I have a 2010 Mazda CX-9 Grand Touring with 66,000 miles.

Has anyone every heard of this? When I accelerate "lightly" going up hills (of which there are many in the Seattle area) my left front wheel sounds and feels like its bouncing on washboard potholes. Its only when going up any sort of grade and only when accelerating. Is it tire balance? Is it CV joint? What is it? Anyone else ever had this happen to them?

By "light" acceleration I mean normal driving. Not putting the pedal to the medal as they say, but just normal going to church acceleration.

Definitely not the tire.

Check the strut for wear and/or leaks as well. Wheel hop could be caused by a bad damper (shock absorber). It's more typical when going over potholes and the like, but it may be the cause of your issue. It is an odd one for sure though.
