I used 100 ft lbs. I also wanted to know the answer but was seeing different answers. I decided to use my torque wrench the opposite way to determine how much torque it required to remove the bolts. My notes are showing that all of my bolts needed 90-95 ft lbs to remove them. I still had the original shocks in my truck. I do remember re-torquing mine, but it may not be necessary.
Extra:
My APU mount bolts are longer and the same bolt material and head size (1-1/8”) as my shocks. The Thermo King APU manual says 100 ft lbs for these mount bolts. Now, shocks go through more of a beating, so I suppose they can be okay with higher than 100.Last edited: Sep 8, 2019
shatteredsquare and LoneRanger Thank this. -
300 a bit high. What bolt size? 5/8 = 185 ft lbs. Or 1/2 inch impact tight does the trick. New lock/stover nuts and no need to retorgue.
pushbroom, PE_T and LoneRanger Thank this. -
Bolt size is 1 1/8th I tightened best I could with hand tools, going to get a torque wrench and finish it off.
-
1-1/8 socket is 3/4 bolt. And 250-300 wont hurt a thing. Hard to overtorque that one.
shatteredsquare and LoneRanger Thank this. -
Do not get a torque wrench from Harbor Freight. Maybe just their smallest one (which I rarely use). These are delicate tools, so you want a better quality brand.LoneRanger Thanks this.

Minimum standard is husky, since it’s lifetime warranty at any Home Depot, would like snap on but rates these days make me ball on a budget.PE_T Thanks this.

Snap-on are overrated and overpriced. If anyone is to really benefit from them is an actual full-time mechanic or a mechanic shop.
-
Yup I worked as one long time ago, I know it’s over rated and over priced but still quality.
Some habits hard to break.

Snap-on torque wrenches are made by CDI, which I believe is now owned by Snap-on. Hard to beat them for accuracy. You can find CDI on Amazon.
Oxbow, Dino soar, LoneRanger and 1 other person Thank this.
