Strut install

Allan28 said:

Looking to change my shocks and struts on my 2018 4wd Colorado, and was curious if anyone knows for sure if the upper arm knuckle will need separated to allow for strut install?

Just looking I realize I will have to remove the sway bar, and thinking it might fit up in place without, separating the upper knuckle but wasn't sure. Just wanted to find out so I know what I'm getting into before doing it?, Thanks

Fondupot videos are good and he's on these forums.

But yes, you will need to disconnect the upper control arm ball joint, sway bar, tie rod, and end links.

It is not difficult, but you must ensure you support the lower control arm to prevent the brake line or ABS sensor wire from holding up the entire assembly, as they can break/cause you issues.

PB blaster might be helpful, but the electrodeposition coating on these trucks is still going strong on my 2016, though I don't live in the snow belt.

Thanks for everyone's info, was thinking with complete removal of sway bar it might be possible, but I was wrong, from the replies. Knowing this I'll know what to find torques on beforehand, Thanks

This should be what you're looking for, however some are awkward to get to with a torque wrench and you may need to tighten until you feel confident.


Front Shock Absorber Upper Nuts (3x): 43 lb ft
Front Shock Absorber Lower Bracket Bolt: First pass: 74 lb ft, final pass 25-35*

Front Stabilizer Shaft Bolt: 37 lb ft

Front Stabilizer Shaft End Link Bolt: 22 lb ft

Steering Linkage Outer Tie Rod Nut: First pass: 26 lb ft, final pass 85-95*

I recommend everyone re-torque or re-tighten suspension components after ~500mi, and then apply DYKEM Cross-Check torque check/seal for easy visual inspection.
