Front Wheel Runout
I have an 2001 F-350 DRW SD and after 30K miles had a terrible shimmy on the front end at 50-60mph. Found some bad tire cupping and replaced. during tire balancing, tech told me that the aluminum wheels were warped. On balancing machine, noted one front wheel at about a 1/8 inch wobble and the other tire less than 1/16 inch. Truck had 10K miles on it when I bought it and it traveled smooth and shimmy developed slowly. Did not hit anything.
Put spare(unused steel wheel at worst warped wheel location) on and and new tires and problem lessened although not gone. now after about 800 miles, shimmy is back big time (feels like warped rotor during braking and terrible out of balance at speed). Has ayone had anything like this oone at all?? Can use any input before I start spending big bucks replacing things if there is knowledge out there that can help.
Thanks in advance

Are you sure you don't have bad bearings or sticking brakes. As far as the 1/8 and 1/16 inch wheel problem I don't think thats too bad. They can be trued. Wish I could help more

Thanks for responding.
The runout was noted with the wheel removed from the trock and mounted on the tire balancing machine. When I first put the spare on (in place of the worst warped al wheel) and the new tire on the other side, braking shimmy dissapeared for several hundred miles before it came back. Also the steering wheel "rocking" back and forth at speed as the wheel(s) apparently wobble. Don't th9ink it is brake or bearing, but that is a thought. I know that under/overtorqueing aluminum wheels can warp them, but I have not experienced problem before and I don't know why it improved w? new tires then got worse again.
Thanks for your response. I'll see if anyone else has some input

I just think you need to look for something other than wheels and tires. I don't think 8 lug wheels are subject to torque problems. Spin the wheels on the truck and see if they wobble more. See if the brakes get hot without using them..

I would say your tires are out of round or balance. That'll make your wheel shimmy.
Find a tire dealer with the road force balancer. Your problem will be found. Theses balancers can tell you if it is a tire, wheel or combo of the two problem.
You can balnce an egg, it won't ride nice, but it'll balance.
