correct torque for control arm linkage?

[bcr4d]

Broke control arm linkage on 00 C4. In the process of replacing it but unsure of the correct torque. Does anyone have the numbers or is there a site that has the settings? thanks

74 lbs to the cross member, 56lbs to the wheel carrier. As a note, the service manual says there are two styles of control arms, and both the control arms on a car must be of the same style.

Note

When replacing tie rods, pay close attention to

the correct allocation.

Install only identical tie rods - version A or

B ~ on a vehicle.

For a detailed explanation - distinguishing

characteristics and Part No. - refer to "Tierod

replacement" (after installation).

Tie rod replacement

Only tie rods with harder rubber mounts

(optimised tie rods with spherical mounts) -

version (8) - are still available from the Parts

Service.

Introduction of the optimised tie rods in the

current model year 1999 (X) in some cases I

but generally from model year 2000 (Y).

Part No. of the optimised tie rod:

996.331.045.10.

These tie rods may be retrofitted - but only in

pairs.

In general, the following applies: Only tie

rods (toe control arms) of the same version

- A or B - may be installed in a vehicle.

In the case of replacement, replace both

tie rods if necessary (install version B).

Visual distinguishing characteristics

between tie rod versions A and B:

The cast number (refer to Fig. 292_99 and

text below the illustration).

The metal bushing of the rubber mount.

On version A, the metal bushing of the

rubber mount is flush with the tie rod.

On version B, the metal bushing of the

rubber mount projects slightly - by approx.

1 mm - at both sides (arrow).

stamped at the end of the cast number in order

to distinguish it (arrow) and was additionally

provided with a blue dot in this area).

Sorry, I would post the diagrams, but for some reason I can only cut and paste the text from my service manual.
