while lying on your back under the column shift steering column..and you unbolt all of the bolts/nuts holding the column..and lower it down.
dont forget that lowering the column moves the shifter linkage..causing the car to come out of park...and will cause the car to roll down the driveway...
and definately dont do this just as you 5yr old child comes over and stands at the open drivers door..to see whats up...
but if you do..this...quickly slam the column back up into position this will return it to park and stop the car from rolling backwards...
almost rendering you fatherless..

definately chock the wheels first..

dont ask me how i know this....shweeeew...

cheapst.
