So I've got a vibration from 50-up mph. I thought maybe the wheels, so I balanced them and the vibration is still there. I have all new u-joints in the prop shaft and can't seem to get rid of the vibration.

Anyone got any ideas.

Can be felt in the whole car and it's almost like a large humming sound, kinda. I can push in the clutch and it's still there and it's there in any gear, so I know it's speed related.

Thanks guys

I would check T-Case and Rear if I were you. Is your yolk resealed?

Just paranoid as I know a few people who've had their T-Cases lock up and you said it doesn't help when you put the clutch in.

Yea I put a new yoke in the t-case and Fluid levels should be good. I checked them about a month ago, no leaks present. So should be good. I'll check the next time I have a moment.

Do your wheels have the correct centering on the hubs?

When I put my aftermarket wheels on, they didn't have the 67.1mm center bore, and even though they were balanced, and get somewhat centered by the lug nuts, it wasn't good enough. I got centering rings for them, and the vibration went away. It was something like $11 off Ebay for the centering rings.

also known as "hub centric rings" they are cheap and should always be used if you have aftermarket wheels.
