ok new to this hope it works ha. around 43 to 53mph only in slight left turns the front left tire has a little to med wobble. if your driving 42mph and you get on the gas it wobbles harder and faster until a lil over 50mph... i dont think it the (death wobble) but it drives me NUTS! ???? oh and it does need a steering box. is that the prob?

 

Any play in the steering anywhere is going to cause some kind of shake. Have you checked the wheel balance? Might have thrown a wheel weight off, thats what caused my problem similar to this.

 

Could be a tire out of balance?

 

Could be the ujoints in the front axle shafts.

I changed out the u joints in my axles and put new hub assemblies on mine and it felt like i went from a 60s military vehicle to a 2010 Catty. Well maybe more like a 1990 catty, but still much better. Not to mentions nothing popped anymore when i was in 4 wheel drive

 

tire pressure maybe. mine wobbled at 46-52 and when i righted the tire pressure it went away. try rotating tires too.

 

Bearings? I guess that falls under hub assembly, huh?
