On Hold Easy help with hydros

Hello im on it again, trying to make a working "car"
i have problem with the steering, right now all my 4 wheels are steering, how do i change it so only the front wheels are steering. I've tried to put it like this
"hydros": [ ["id1:","id2:"],
["b0","b7",{"factor":0.05,"steeringWheelLock":460,"lockDegrees":25}], FRONT
["b5","b9",{"factor":-0.05,"steeringWheelLock":460,"lockDegrees":25}], FRONT
["b11","b3",{"factor":0,"steeringWheelLock":460,"lockDegrees":25}], RARE
["b6","b1",{"factor":0,"steeringWheelLock":460,"lockDegrees":25}], RARE

]

but the game crashes..

I've tried

"hydros": [ ["id1:","id2:"],
["b0","b7",{"factor":0.05,"steeringWheelLock":460,"lockDegrees":25}], FRONT
["b5","b9",{"factor":-0.05,"steeringWheelLock":460,"lockDegrees":25}], FRONT

]
but my wheels loosen and fall off.

please help a neewbie like me get his car working

 

Just create standard beams to the "rear steering nodes". Then it'll hold in place.

 

Thx i figured it out that there were another code for hydros! Thanks
