Do coils go bad?

Hey all, I've had Billie 5100s on all 4 corners for about 100k and eibach 620 coils. The shocks are def being replaced. I did the rears, how hard are the fronts?

Also do coils get worn out? If so what are the clues?
I have a avid off-road light bar, blower, and sliders

Springs can wear out, but generally if they're not rusted and were specced properly for the weight rating of the vehicle you'll be fine to reuse, especially if they only have 100k on them. You're likely feeling the effects of improper damping with the shocks blown out.

To replace the fronts, you'll need to remove the coilover from the truck and use spring compressors to safely remove the shock from the coilover assembly.

 

Thank you
