Hi,

I have a 21 ranger and since i got it (used) ive noticed a low end rumble in the front above about 55+... you. an feel it in the floor boards and wheel. never really thought anything about it. a few weeks ago i installed the fox 2.0 leveling kit and new tie rods full. I noticed a increase in the rumble now. I just had a aligement done and wheel balance done but its still there. Wondering where i should look?

A few notes are that everything looks good not obvious issues ( Minus one which i will note)...

Things ive checked to start
Drive shaft is newer, its firm no play, bushing looks good, its maybe sitting a little closer to the bottom than center but thats it.
All front end bushing look good.

The only thing i could find was some play in what i think is the Pass Wheel bearing... If i grab the bottom of the wheel and push/pull i can get some movement but i dont hear any bad noises or anything coming from it. Guessing i should replace it? but i think this this is the issue...

Here are some photos of the CV's for reference. ii think everything looks fine? maybe a slight gab on the driver side inner boot like its not all the way in?

Any help would be amazing!!!

There are a few threads you might try searching through... i know because I've had similar. Rumble/shake at a particular speed. For me it was tire pressure too low.

Were the tires RoadForce balanced?

A bad wheel bearing often makes a growling sound. Yours might be bad.
