Growl/Vibration noise?

[OHBandit]

I am getting a growl/vibration from somewhere. It is mainly when I am slowing down slowly at below 30 m.p.h. Kinda feels like going over rumble strips but not that bad or like riding on real aggressive mud tires. Thinking possible carrier bearing and/or U-joints in drive shaft. What do you think?

does it feel like a pulsing in a way?

First thing I would do is to manually lock the front hubs IN (you don't have to be in 4WD, just so the front axle is turning with the tires). Drive it around and see if that noise is still there.

If that solves the problem you need to replace the Needle Brgs in the hubs (cheap & easy..)

Front hubs are almost new. Don't think this is the problem.

On hot days when my grease is thinner, my drive shaft will vibrate at about 55mph.
It's almost like what you describe, just not terribly bad.

Drove it in this morning to work...hadn't driven it in a few days. Seemed worse right when I first started driving and a little better after I got down the road but never went away.

Yea, well, the needle bearings aren't actually in those new hubs

Give it a try anyway...

Maybe pull the ft driveshaft and drive it, that would eliminate the Carden & Slip Joints (and the Only way to really check those while it's out)

Appreciate the help and tips. Where are the needle bearings? I have replaced both front wheel bearing/hub assemblies within the past 2 years. Really feels like it is coming from the back end.

Ahh, that's different The needles Are part of the Ft bearing assembly and I don't think I understood it was coming more from the back..

If you have a 2-piece driveshaft I would Definitely take down the carrier bearing and go over it. In fact, just like the ft driveshaft, often the only way to really check those U-Joints is not in place, but in your hand. Take the rear driveshaft down and give it all a good look!


EDIT: Have you not yet tried locking those hubs? I mean, it still IS the First thing I would do... It's just So Easy to try and, no matter where it sounds like it's coming from, your "rumble strip" description is spot-on for what they sound like when bad. - What's stopping you from trying it?
