Hard Bump Suspension Compression Measurement

Now the fun part. Find a deep ditch or gully and drive your truck in it at an angle (an RTI ramp works well also). This will twist up the suspension to near full bump. If you get one front tire and the opposing rear tire down in the ditch and the suspension flexed up so the up axle ends are at full compression, then it's time to set your parking brake and remeasure from the tire to any close hard parts.
