Today I brought my car to my mechanic to grease the intermidiate shaft because I was getting that crunchy steering wheel feel. The I.*. was greased about a year ago with no issues till now. When the mechanic removed the I.*. he showed me that it had plenty of grease in it and looked to be in good shape. He reinstalled the I.*. and when I drove the car the crunching noise dissapeared. The mechanic'* theory is that the bolts that hold the shaft get loose after a certain amount of time and that'* what causes the noise we hear. I've been driving the car all day and the steering is as smooth as silk. Is this a possible cause and or solution?
It'* hard to say for sure in your case. However, I've had the shafts out of a couple of cars a few times to take care of the clunking and each time the bolts were plenty tight. If I had to make a guess, it was more likely the longer movement of the shaft while it was out that dispersed the grease along the shaft, and that is what has made it quieter.
He said he has serviced two other 2001 bonnevilles with the same problem and he remembers the bolts not being as tight as they should be. Archon'* theory makes a lot more sense. I will let everyone know if or when the crunching sound comes back. Thanks for your input.
My experience has been that it is the colder weather that seems to start it up again, so I'd expect next fall at the earliest. Generally, it takes a year or two before the clunking starts again. Keep your fingers crossed that you beat the odds.
