Just an FYI. I have been ignoring a slight aggrevating shake in the steering wheel for quite some time. I just assumed tire out of balance or slightly warped front rotor or some ball joint work due to approaching 80,000 miles. Well the slightly warped rotor became much worse so i dove into the front brakes. Long story short it ended up being the rear brake rotor/caliper sticking transferring the vibration to the steering wheel. With two other vehicles to maintain i missed/neglected the rear hardware on the truck. So keep the rear brake hardware on your radar for a front end shimy. Its gone now and a pleasure to drive again. I do have the crew cab and 8' bed which gives the rear end a long lever.

 

Good info. Last place you'd look for a front end vib.
