Table 1 shows two common suspension related problems of the 2001 Chevrolet 2500.
| Problem Category | Number of Problems |
|---|---|
| Rear Suspension Springs problems | |
| Front Suspension Control Arm problems |
The vehicle often times vibrates in the speed range from 10 mph to 70 mph. Within the times the vehicle is vibrating in the speed range of 50-70, occasionally the vehicle will jump within the lane, on the order of quarter or halves of a foot. Towing generally minimizes the vibration; however now, steering gets more emphasized and sloppy, with a less in control feeling. I have brought the vehicle to a Chevrolet dealership and they have done their best to minimize the vibration by making minor/scheduled maintenance adjustments to the vehicle, yet the problem still persists. I have suspected the rear differential, front springs, tires, and suspension, but I am not sure what component or combination of components are the root cause of the problem.
Upper a-frame/ control arm rotted away, perforating around ball joint, allowing ball joint to break off vehicle. Extensive rot all over vehicle underside for last 10 years.
