    Front control arms torque specs?

    I don't have a bentleys and I'll be changing out my control arms this weekend. Does anyone have the torque specs for all the front control arms and tie rod ends?

    TIA

    In case you need it 1 Nm == .7375 lb/ft. I still have a torque wrench kicking around without the Nm measurement on it. Eventually you get good at doing the math.

    ^ all those torque specs are from the bentley front suspension overview. The tie rod ends aren't shown in the diagram but #5 and #7 are the tie rod end hardware.

    The suspension pivot bushing bolts/nuts must only be torqued to spec with the suspension sitting at the loaded ride height position. If torqued with the suspension extended, the bushings will be damaged when the suspension is compressed from the extended position. You can torque the bushings just enough to eliminate any free play, then carefully drive to a nearby shop to have the suspension re-torqued to spec with the car on a roll on hoist. It's practically impossible to do this right on the ground. Another way is to remove the front wheels, and using a bracket that bolts to the wheel hub face and the floor jack pad, support the weight of the car at that wheel and lift the car with the jack to compress the suspension before torquing anything. Limited torque wrench swing space will be a hassle with this method. Be careful with this or your new control arm bushings can be damaged as soon as you drive the car. The reason for all this is the requirement to prevent having any twisting stress in the bushing rubber when the car is sitting on it's wheels at the normal loaded ride height for your A4.
