Unsolved Steering doesn't work if wheels are on

Hello community,
I am just wondering if there is a way to fix an issue where the hydros don't work or completely break when the wheels are attached. I am following the Content Creation guide but it's fairly confusing for a beginner like me, and some of the content in the guide is outdated.

Here is the section I believe is causing the issue:

"slotType" : "main",

"flexbodies": [
["mesh", "[group]:", "nonFlexMaterials"],
["test_body", ["test_body_g"]],
],

"hydros": [
["id1:","id2:"],

["nl0","bl0",{"factor":0.05,"steeringWheelLock":180,"lockDegrees":25}],
["nr5","br5",{"factor":-0.05,"steeringWheelLock":180,"lockDegrees":25}],
{"beamPrecompression":1},
