Symptoms
The ride feels busy and jittery over small bumps when the bed is empty. Forum owners say the wagon doesn't do this.
The fix, step by step
- Owners blame the longer wheelbase, the springs rated for payload, and possibly the bed mounts.
- One owner fitted Radflo adjustable shocks and reports a good ride on and off road.
- Another fitted MetalCloak suspension and still felt the jitter.
- Ineos's Kaiju build used JMACX remote-reservoir shocks.
- Adding the load you actually carry often settles it first, so try that before you spend money.
Tools & part numbers
- Floor jack
