So tonight in the airport parking garage I noticed a click from the left rear wheel when accelerating from a stop. I think it's an issue of the spindle nut not being tight enough. I did some searching and it seems like this is the case. My only fear is that due to the mileage on the car it might be too late to get by with just re-tightening and re-staking (or completely replacing) the spindle nut. I might need to replace the hub and wheel bearing as well. Though I didn't notice it when testing the car last week, so maybe it's a new development and re-tightening will be fine.
Parts are not expensive, but it seems like a PITA. I guess I'll look into it this weekend.
In happier news, the suitcase fits!
