Help with Front End Vibration

I'll start with what I have and what I have done thus far. I have a 2008 F250 with a 6" Pro Comp lift and 37's. Ever since I've had the truck, it has drive like a million bucks. No shake, shimmy in the front end what so ever.

About three weeks ago, I started to get a little growl in the front end and experienced some death wobble when I hit a good size bump. So last week, I changed out the hub assembly on each side. The growl and death wobble is gone, but now I have a vibration in the steering wheel, but it's only at certain speeds. I went back a double checked the torque on all my bolts and lugnuts, even checked the auto locking hubs, as I've of problems with them staying engaged. Everything on the front end looks good, so I'm having a hate time figuring out the vibration.

Any ideas? New front end alignment, rotate tires, u-joints????

I just finished identifying and resolving a Death Wobble issue I was having.
I first replaced the Track Bar on my 2008 F250 because the driver side
bushing was obviously bad. Once that was replaced, the death wobble still
persisted. I then replaced the Steering Stabilizer shock, but that also didn't
resolve the issue.

Finally in my attempts to get a wheel alignment done, the techs brought my
attention to the Tie Rod Ends that were lose. Sure enough both driver and
passenger side tie rod ends were bad. Once I got those replaced and the
wheel alignment done, the death wobble went away...


So if I was you, I would check:

* Track Bar
* Steering Stabilizer Shock
* Tie Rod Ends
* Linkage to Steering Box

If none of those issues pan out to be a problem, it's likely the Ball Joints
which may end up costing a pretty penny to be fixed. Although some
dude did a Youtube video if you have the time to DIY it.

Thanks for the reply ALBY. I forgot to mention that I recently upgrade to the dual steering stablizer shocks. It was a band-aid to say the least. I did take the truck by a local 4x4 dealer and they did once over for me and found the drag-links and the gear box was trashed. They double checked the track bar, but said it was fine...for now. I have a new steering box and drag links on order. I hope the new parts and an alignment fixes the problem.

I've reached the point that I'm sick of the costly repairs on this Super Duty.
With my truck back in tip top shape, I'm gonna sell it and downgrade to a
F150, specifically a 2009 or 2010 F150 Lariat. I figure the proceeds from a
sale will allow me to buy the used F150 in full and have a couple thousand
dollars left over for upgrades.

My 6.4 had a rough vibration and the transfer case actually snapped off the front and rear driveshafts when I slowed down. The bolts on the transfer case come loose.
