Since i got my already lifted 2008 Jeep Wrangler Sahara Unlimited. 50-60% of the time when i hit a certain type of bump with my FRONT RIGHT tire it starts to shake and wobble like crazy. Feels like the wheel is gonna fall off. When i slow down to 15-20 MPH it stops. I just went mudding today and when i was driving i hit 30MPH and it wobbles. I cant go past 30 without it doing this now. Is it the death wobble? I really hope not. Thank you all

 

You caught the death wobble, son. There's some great diagnostics threads and video links in the modified tech section. I used them to diagnose a friends 07 jku.

 

I'd check your tire balance as well even though an off-balance tire is usually isolated to a certain speed range.
