2002 Pontiac Bonneville pop in steering when turning the wh

I'm not a mechanic, but there's techical service bulletin on this issue and the culprit seems to be the intermediate shaft on the steering column. From what I can gather, some say it needs replaced while others say it simply needs lubricated. Pontiac sells lubrication kits for 15 bucks but it's an hour and a half job, according to my dealer. The lube job makes the sound go away only temporarilty. It's supposedly not a safety issue - only an annoyance.
