{"text":"Got an 07 4900 that used to ride like a Cadillac. Last winter I started noticing smaller bumps getting bigger. Now when I see a decent bump in the road I cringe, which seems to be every 5-10 seconds. I've had all 3 axles gone through and ride height checked on steer, drives and cab. Replaced all 10 shocks, worn airbags replaced, spring bushings replaced, leveling valves replaced. Replaced steer tires. Drive tires are still in good shape minus a minor cup on one. The roughness travels throughout the entire truck, but I can time the bumps and am certain it's coming from both drive axles. The bumps are jarring almost to the point of my drinks in my cup holder ending up on my dash. Rough roads are completely unbearable and rattle the whole truck apart. I have been having other issues with leaks, wiring issues and loose/broken bolts and parts due to how bad the ride is as well. Anyone else experience this and find the solution?","pics":"[]","canComment":true}
