I have 2009 X with a 3.5” RE lift and 35” Procomp tires. In the winter, DW or hard shimmy and lot of steering feedback is almost a daily thing. However in the summer it almost completely goes away. I run the same tire pressures all year long. I drive the same roads, hit the same bumps that in the winter sets it off, in the summer nothing.

Just thought it was interesting.

Maybe it's a bushing or joint that contracts when cold and thus introduces play?

 

Looked at everything twice. Going to increase caster before this winter just to see what happens.
