Torque spec. for s80 axle and control arm? S80

posted by  someone claiming to be long-gone on  Tue Mar 18 18:31 CST 2008 [RELATED]

Hi Lane, The specs I found (from a non-Volvo source) for my [early] '99 S80 are:

Control Arm to/ Subframe (front 2 bolts); stage 1: 48 ftlb, stage 2; angle tighten 90°
Control Arm to/ Subframe (rear bolt/nut); stage 1: 77 ftlb, stage 2; angle tighten 90°
*I have no info wether the car has to be loaded or not.

Shock Absorber/Steering Arm (how the reference termed it): stage 1: 77.5 ftlb, stage 2: angle tighten 60°

Hub / Steering Knuckle (4 bolts); stage 1: 15 ftlb, stage 2: 33 ftlb, stage 3: angle tighten 60°

*Axle Bolt; 37 ± 9 ftlb
*note: on my '99 this is a small (M10 / 14mm I believe) bolt. I think I've heard that it's like a 34mm nut on other years so the spec would likely be different.

Of course, since these specs aren't directly from an official type Volvo source, I can't be 100% confident they are correct, and as mentioned, were ascertained for my early '99 S80, in which many things changed in proceeding years.

It's always recommended that critical/high load bolts be replaced with new ones.
Hope this helps.
