Assuming it is an intermediate shaft, is this a safety issue if left alone or just annoying?
thats arguable, as a developing comdition it is just an annoyance, however the problem COULD progress to the point of a u-joint failure in the shaft ultimately eliminating your ability to steer. the odds of this actually happening are slim to none
Thanks for the info. guys. I work with a former GM-certified mechanic so we're going to at least take a look at it and see what we think. Doesn't bother me a whole lot but if we can fix it I'd like to.
