New shop down the road (within walking distance) put a rear cover gasket and rear main seal on for me last week. They called and said that they may have inadvertently damaged the tailshaft extension housing seal and were going to put a new one on. Score! I like honesty. Picked it up and drove it for a half hour or so running a couple of errands and all was well. Later that evening, went to pick up one of our dogs from the vet and once I hit 40MPH, I hear this terrible whine/squeal/screech. It sounded electrical, so I kill the radio and HVAC. Seemed to disappear under 20MPH. Nope, not electrical. Dang. I take a look underneath and the seal doesn't look like what I remembered.
The next day, I get the GoPro out and take a couple of videos. I take it back on Monday and take the manager for a ride. He hears it. We put it on their drive on lift that has a neeatsecondary lift to put the wheels in the air while the vehicle is raised enough to walk under. It's coming from that seal. He said that he saw there's two part numbers and he'd get a new one from GM and put that in. They drop me off at home and call later that it's ready. They pick me up and I ask if about the different part number and they put one that looked like the old. No more noise!
Edit: watch the volume, it's horrific sounding!
TLDR: There are two seals for the tailshaft extension housing listed - one with a boot (24232325) and the other without (24232324). Pay attention to what your vehicle came with. They were doing me a favor replacing it since they didn't know if they broke it during the original repair. That's valuable in a shop. Then they stood by their work and made it right when it wasn't. That's valuable in a shop. Even though the place is within walking distance, they shuttled me to and from home several times. That's valuable in a shop.
