Worn Out Rack and Pinion Rack/Bushings?

My trucks front right suspension area makes a knocking noise when pulling into my driveway and when going over bumps in road, I replaced the heim joints about a year ago, it may be those but sounds like more to the middle of the front suspension, when the front left wheel is raised you can see that there is a bit of play in the rubber bushing areas (two of em), 2012 taco 6" fabtech with 34's, 31,000 miles on truck a bit of towing of my 14' camplight trailer. Anyone else experience these annoying noises?? I'm also wondering if it can be under warrenty still?

Thanks all...

 

are those poly urethane bushings or just the same oem style ones?
