Double star tires

Will probably be worth trying to balance tires,because buying all new drives will be expensive.

 

Also, is you suspect the tires to be out of round or have a hop to them, its not a bad idea to take the tires to a big tire retread shop and let them put them on a milling machine. It will true them up and make them round again. Alot of work, but worth it in the end if the tires arent junk.

Youd be surprised how much rubber they shave off of a new bridgestone or michillen tire sometimes.

 

Also check your carrier bearing.

 

Check all your engine Mounts.
if they're worn? When under load the torque twist of the motor can alter your driveline angles causing driveline shudder/vibrations..

Ask me how I know this...lol

 

I can tell you first hand that a Double Star tire won't last very long without failure on a spread axle trailer (front).
