Sis bought an 08 equinox in 2010 w/20k miles. It had a noise from steering column. My kid bought it several years ago and it still has noise. It has elec steering and boost motor is under dash. I changed u-joint in column and no difference. Is it possible coupler was noisy at 2yrs? How could a coupler be worn @20k miles?
I got a used assy and plan was replace it all. Maybe it is plastic coupler item? Take it apart and look I reckon.
My daughters saturn had some wierd noises, I’ll know what it is when it breaks. Ended up being a timing chain, Oil lubrication failed. I do not like chasing ghosts.
The video is from 5-6 yrs ago. He took out steering column and wiggled steering wheel and you can hear clunk sound. From the elec motor unit. A number of videos online about the plastic coupler. I made wild assumption I didn’t have the coupler. Turns out I do.
It will be interesting to know what you find out.
