Elec steering motor.

[cavell]

Kid has rattle in column. I replaced knuckle assy. I’m pretty sure it is from motor assy. Found a nox in yard with no dash and exposed steering column. Took 5 min to remove motor assy. So, I am going to swap it out on nox. I have never seen this mentioned at site. But, I see this part removed on many noxs in junkyards. Is it never discussed?

and I see many more Saturn vues with part removed. I have both. Vue has same elec steering setup.

Might have been a bad batch of motors from whichever factory made them. We haven't had the issue with 210k miles so far. The steering assist issue may have been something like the large number of '05 A/C compressors released from spain in '04 with no PAG oil inserted before putting the caps on. We were 'lucky' to get 2 of those with our cars.

My sister bought equinox with 20k miles in 2010. I drove it and it had rattle. My kid bought it 2 yrs ago and rattle remained. So it’s my problem to solve. On icy, rutted roads it is REALLY annoying.
I can’t imagine any GM car would rattle at 20k miles. Haha

I do see I have a plastic coupler drive insert that lessens harshness. Seen videos showing they may deteriorate over time. I will inspect mine.

BUT, I have rattle when car is off. So elec motor has no power. So motor should not be providing boost. I assume when I turn wheel the shaft is then trying to apply load to motor so it could make noise in that case?

Changed assy this weekend. The steering column has spline on both ends. Input/output. It is easy to have offfcenter steering when done. You adjust things and all is well. I’d say rattle is gone but sound remains when you drive over curb. So, it not fully fixed.
