Odd Vibration In Floor And Gas Pedal

So I greased everything underneath yesterday and the vibration is still there unfortunately, but at least I know to do it now. Guess I’ll just have to take it to someone this weekend and see if they’ll have any luck with it

 

Needle bearing in the front diff. can cause viberations

 

Another update. I was told in September, by Discount Tire, that my tires were slightly cupped. The shop that I took it to a couple of months back said the same thing, but didn’t necessarily attribute that to my issues. Michelin Defender LTX all with about 8/32 of tread left. I took the plunge 2 weeks ago and replaced them with new Defenders. Majority of the vibration and odd sounds are gone. Can still feel a little vibration, but can definitely live with it. Still hearing a slight whining sound above 30mph, but it’s not loud. Just annoying. Not sure how they got cupped in the first place, but those were the tires I bought it with. A little nervous that there is an underlying issue that caused it since the vibration isn’t completely gone, but no one has said that there is anything wrong with the suspension. One person even complimented how nice the ride was and that it braked fine.

 

Glad you got it solved! Having a good alignment can prevent cupping from happening. But sometimes it seems cupping can happen for no good reason. I suspect some tread designs are more prone to it. And once it starts, they just cup deeper and deeper.
