Steering shimmy problem

[dhdaniel]

I have an '06 with 39337 miles, Don't drive this truck much but I noticed I have
a slight wobble/shimmy in the steering wheel at 45-50 mph,

What could possibly cause this, what should I be looking for?

I just now jacked it up and tried moving each front tire looking for slack in a tie rod or the rack, but it seems tight as I would expect for low miles

I just recently installed new Front shocks, New tires,

kinda puzzled

thank you

has it sat for 30ish days in a row?

you might have gotten flat spots in the tires which should wear out of them in about 20 miles.

Might also be tire balance or pull. Try rotating them. Cross the fronts and bring the rears straight forward.
