Front Suspension Torque Values
How do you determine which torque value to use for the front control arm and torque strut? I have found two different values based on bolt size. This is for a 2012 GLK350 Base.
(RWD) Lower control arm (cross strut) to subframe M14x115 = 80Nm + 120 degrees
(RWD & 4matic) Lower control arm (cross strut) to subframe M14x120 = 120Nm + 180 degrees
(RWD) Lower control arm to spindle = 50Nm + 60 degrees
(RWD) Torque strut to subframe M14x115 = 80Nm (60 ftlbs) + 120 degrees
(RWD & 4matic) Torque strut to subframe M14x120 = 120Nm + 180 degrees
(RWD) Torque strut to spindle = 50Nm (37 ftlbs) + 60 degrees
(RWD) Lower control arm (cross strut) to subframe M14x115 = 80Nm + 120 degrees
(RWD & 4matic) Lower control arm (cross strut) to subframe M14x120 = 120Nm + 180 degrees
(RWD) Lower control arm to spindle = 50Nm + 60 degrees
(RWD) Torque strut to subframe M14x115 = 80Nm (60 ftlbs) + 120 degrees
(RWD & 4matic) Torque strut to subframe M14x120 = 120Nm + 180 degrees
(RWD) Torque strut to spindle = 50Nm (37 ftlbs) + 60 degrees

Seems the answer is in that sentence ... did you measure the bolt size in your GLK??

I'd like to be able to know before I start if the different bolt sizes were tied to a specific year or something else. Weird thing is that all the videos I have seen only use the lower torque value, even on 4Matic.
Just wondering if someone knew
