Intermittent vibration

Hi all, Ive seen similar posts but not sure I found my issue. I have an intermittent vibration that is not constent with wheel speed. I had assumed it was wheel bearings because of the griding sensation. After inspection, the wheel bearings are fine. Vibration most noticable at 15-45 mph. The vibration does not seem significantly effect by turning one direction or the other but does seem very slightly more noticable when road is uneven and is lower on passenger side.
The vibration is almost comes and goes at almost the same intervals regaurdless of speed, almost like Im hitting a less signifcant version of highway rumble strips every couple seconds. Seems to be getting worse....
Any insight?

 

have you had your wheels and tires road force balanced? . I was getting all sorts of on and off vibrations from my wildpeaks when they were new. I brought them to a legit tire shop and had them RF balanced. It made a huge difference. I do feel like these tires have increased road feel compared to other tires I've had. I feel more of the imperfections of the road.

 

If u have any lift on the truck I would say it’s the needle bearing on the drivers side of the front differential. It’s a common problem with these trucks. The best fix without replacing the diff is a piece that replaces the bearing and is made by east coast gear supply. There’s plenty of info on this topic on this site.

 

Only 884's which should only be 1.75" to 2". Ill look into needle bearing!

 

Not tires, noise not consisten with wheel speed. But yes the wildpeaks are an awesome tire but transer lots of road noise.

 

I bet the bearing is the issue. If u put the lift on yourself u should be mechanically inclined enough to change it yourself. ECGS also sells a bearing puller made just for this that makes the job a lot easier. Also if change your axle seal while your in there.

 

Does the noise go away or get substantially quieter when you go to 4WD?
If so, it’s probably the needle bearing.

FWIW, my wheel bearings didn’t seem bad when I checked them with the truck wheels off the ground. They only made a noise when the load of the truck was on the wheels.

 

Thanks! I think Im going to order the needle bearing. The lift is new and I didnt notice the noise till months later.
Is it doing any significant damage to be driving it daily in the meantime?

 

Yeah there's a lot of folks who have been told their wheel bearings are fine but it turns out to be the cause anyway. But yours is a 2014 and I believe at that point they were using the upgraded wheel bearings so less likely, just don't rule it out completely.

 

You’ll probably be fine driving it until you get the bushing.
If you drive on it for a long time . It could start to come apart. And that would suck if the needles went into the Diff.

TBH, the pictures I’ve seen where the bearing started to come apart looked, almost like the puller did the damage.

Anyway, I’d order the bushing. Drive the truck in the mean time. Then install the bushing the first chance I get.
Of course, that’s what I’d do. Because it’s my only vehicle and I do what I have do.

 

Yep, I agree here.

 

Ive had just enough experience with wheel bearings to make myself think I know what Im talking about.lol. I did a pretty good inspection and certain in my own mind its not the issue. Something Ill be keeping an eye on for sure though.
