Road noise
It seems that road noise is getting louder in my rig. Especially on washboard roads, or roads with ice ridges. Noise seems to be centered in the left front area. Ball joints were replaced 50,000 miles ago and still feel tight. I replaced the front shocks a few months ago. Jacking the front up and manipulating the tires to identify play is not productive. Truck has 200,000 miles on mostly paved road.
Questions: What bushings up front are generally the first to wear out? Is there anything else I should be looking at? Thanks in advance.

Only superficially and by trying to manually move them to assess play. All "seems" fairly tight.
However after 200,000 miles I'm sure the bushing material has seen a reduction in elasticity.

I don't know which bushing wears out first but you might as well replace all of them while you have the front end apart. I used these on mine and the front end quietened quite a bit.

Also check your cab mounts.

Thanks. I may do a deep dive in the spring and replace them all. My money is on the leaf spring bushings.

What he said. I put new shocks on mine and helped a ton but still has banging when over bumps. My drag links were badly worn and it was a new truck after I replaced them. The swaybar bushings are older but still in good condition. I will probably replace them next prophylactically this year.

Okay, replaced sway bar bushings and end links today. Bushings were probably okay, links were definitely tired. Seems to have improved things a little. Greased ball joints and this helped somewhat. Test drives were short. Thanks for the help and input.
