Got tired of the "popping" sensation in my steering wheel when turning back and forth...and I knew that a trip to the dealership would yield a "we don't notice it" response and wasted time and gas. So.. I fixed it myself.
Used: Ratchets, long extensions, 13mm socket, grease, flat blade screwdriver, wire snippers.
First, make sure you keep up with the position of your steering wheel! You must reinstall everything with the wheel in the exact position it was in relative to the tires that it was in before you started.
Now, remove the 13mm bolt at the upper end of the steering shaft. Then remove the one at the bottom end (near the A/C compressor). It helps to turn the steering wheel so that the bolt heads face up, and then you can use 13mm socket with long extensions to get the bolts out. Remove this intermediate steering shaft from the vehicle.
Now, using a flat blade screwdriver, pry up on the band clamp release notch on one end of the rubber boot. This will release the clamp and allow you to slide the rubber boot off the shaft exposing the splines.
Grease the splines thoroughly. Then work the two halfs together a few times and grease again. Reinstall the boot and reattach the band clamp. If you have trouble reusing the band clamp, a tie strap will work also.
Reinstall the shaft back in the vehicle and tighten the 13mm bolts TO SPEC. MAKE SURE YOU PROPERLY TORQUE THE BOLTS. You do NOT want these bolts coming loose on the highway. Again, keep track of the position of the steering wheel to the tires throughout this process.
Total time spent: 20 minutes. No more popping and no trip to the stealership.
