Have a 2007 Dodge 3500 Ram 4x4 dually mega cab 6.7 cummims
Have a bad vibration at 50 mph and over checked u joints in drive shafts front end axles seens ok Thinking has to be in the Rims Or tires or the balancing of the 6 tires is there any thing i could be missing here..

 

Ujoint problems are very common on 3rd gen trucks, and you may not be able to see the problem just by getting under the truck and feeling the joints for looseness. Sometimes one of a joint's cups will be seized solid and you won't be able to find it unless you remove the shaft completely from the truck and rotate each joint through its arc.

Just pointing that out because I've seen that many many times. You could very well have a tire out of round or out of balance, bent wheel etc.

Hope you find something.

 

Thanks for the replying I am going to have the tires getting spin balanced Never thought about a frozen ujoint

Thanks again
