I have a 2002 Bonneville SLE with 19000 miles. I recently just relubricated the intermediate shaft since it was causing friction while turning. After I installed it, I took it for a test drive and that problem was solved but unfortunately the steering wheel was 1 too many revolutions to the right so when i maxed my right turn i heard crunching in the column and the "service airbag" light came on. I readjusted the steering wheel correctly but its too late. I did some research and found that it is probably the SIR coil.

I can't seem to find information on anyone that has fixed this problem so I'm wondering if anyone knows if thats probably the problem, whats involved to change it, and most importantly how much one of those costs. Thank you
