weird vibration????

[Sullie250]

I have a vibration coming from the front of my truck. i cant figure out what it is. I balanced and rotated the tires, just had ball joints and wheel bearings done about a year ago, and i cant seem to find out what it is. i am not sure if it is steering or suspension or something in the drive train. it seems to do it at all speeds over 30mph and gets worse around 60mph. any ideas?

Does it feel like rumble strips? Try locking your hubs and go for a drive if it goes away i almoat guarntee its the needle bearings in the hub

i will give that a try and see what happens. thanks

I just finished chasing out a vibration I was having that sounds similar. It felt like it was right up in the front end, but was the rear u-joint. Pretty simple to check/fix.

thats what if kind of felt like too. but i just threw a rear drive shaft and put new u joints on from the rear diff to the tranny as well as a new drive shaft. and with the needle bearrings in the locking hubs....can i pull them apart and grease them?
