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.
