I had a similar problem with my 93 SSE. Ended up just replacing the bearing since I was getting the breaks and wheel bearing done at the same time. It was nice to have a friend who is a mechanic and his brother work at NAPA so it didn't cost much(part and dinner for 2) I kinda wished I had know about this little trick. Might have fixed my problem.
Good to hear that it has helped with your problem. Keep up updated if it comes back at all cause I am interested to see how well this solution works.
