Front stabilizer bar torque

[Ubermensch]

I've got some serious creaking and groaning from the front end on my 2001 C4. When I press directly above either shock I can replicate the noise. I was planning on checking the torque on the stabilizer bar as I found recommended in a few other posts and ran into some confusion. Here are the specs from the manual:

Specifications - Front Suspension

Notes Stabilizer On Side Member 65 Nm

Stabilizer Mount On Stabilizer 46 Nm

Stabilizer Mount At Shock-Absorber Tube And Wheel Carrier

Note: Carrera 2 85 Nm

Stabilizer Mount At Spring Strut

Note: Carrera 4/911 GT3 46 Nm

Stabilizer Mating Bearing On Spring Strut

Note: (lock nut) 911 GT3 50 Nm

Here's a picture of the connections in the shock area:

If I'm trying to torque the bolts on part #19, which torque values do I use 46 Nm on both or 46 Nm on one and 65 Nm on the other. Where is the connection to the "side member"?

I wouldn't be surprised if the source of the creaking and groaning was number 14, which is an axial ball bearing. Does it also make this noise when you turn the steering wheel?

In answer to your question: On a C4, it should be 46Nm top and bottom, because both bolts are M10. On a C2 it's different, because the top one attached to the wheel carrier is M12.

Cheers,

The nut that attaches to the stabilizer (the lower one) is 46Nm (stabilizer to stabilizer mount). The other end is 85Nm (stabilizer mount to spring strut/wheel carrier).

No noise when I turn the wheel. I only notice it at low speeds once the car is warmed up a bit.

So we've got a vote for 45 Nm on both since ar38070's comments pertain to the C2.

Any idea where the mount to the "side member" is?

Part #20 is the combined cross member and side members. Stabiliser on side member is part #18.

If there is no noise when turning the wheel, I don't think the bearing #14 is to blame.
