I just got my drive shaft replaced after waiting too long. Prior to the repair it was rattling, in the direction of the back right wheel. It would get a lot worse if I was carrying things in the back. Since the repair that has been totally fixed last week.
However, I made a long drive from Boston to Blue Hill, Maine, last weekend, where we drove around a lot and on the way back (I think that’s when it started) it began getting pretty loud at highway speeds – it sounds like an accelerating motorcycle – in the same vicinity as the old rattle.
I’m going to take it back to my mechanic and see what’s up but wanted to hear all of your thoughts too. The pater things its a u-bolt because I ignored the drive shaft problem (I am sorry! Do not shame me further than I have already been shamed) and I am hoping its just that my tires need alignment or similar and is not related to the drive shaft? I tested the drift last night and it did list to the right, but then this morning I tested again and it seemed fine.
Edit: I got an oil change this month, prior to the roadtrip and have another 2k miles to go until I am due for another.
