Correct Torque Specs for Suspension Components
Reposting in mechanical section for better coverage:
Real quick, are these the correct torque specs for suspension components on a e90 330xi? I've seen a number of different specs floating around - some even said Bentley manual was incorrect. Can someone confirm that these specs are correct? Ordered M14 10.9 grade nuts off FCP Euro for tension strut, control arm, and tie rod ends. Only need to remove to replace a bad CV axle. Tension strut to steering knuckle (replace with new) 165 Nm (122 ft-lb) Tension strut to subframe • M12 8.8 (replace with new) 68 Nm (50 ft-lb) + 90° • M12 10.9 (replace with new) 100 Nm (74 ft-lb) + 90° Control arm to steering knuckle • M14 8.8 bolt (replace with new) 80 Nm (59 ft-lb) • M14 10.9 bolt (replace with new) 165 Nm (122 ft-lb) Control arm to subframe • M12 8.8 bolt (replace with new) 68 Nm (50 ft-lb) + 90° • M12 10.9 bolt (replace with new) 100 Nm (74 ft-lb) + 90° Tie rod end to tie rod (pinch bolt) 40 Nm (30 ft-lb) Tie rod to steering knuckle (use new nut) 80 Nm (59 ft-lb) Stabilizer bar link to stabilizer bar • M8 bolts (replace with new) 21 Nm (16 ft-lb) • M10 bolts (replace with new) 60 Nm (44 ft-lb) Stabilizer bar link to strut • M1 0 bolts (replace with new) 58 Nm (43 ft-lb) |

Those generally look correct. But it's not a race car or space vehicle. The bolt will tell you when its tight. Precision here is not critical.

If you can money-shift it, it's a manual transmission. "Yeah, but NO ONE puts an automatic trans shift knob on a manual transmission."
