2013 Spark with 48,000 miles and one of my wheel bearings is bad. 36K Warranty is over and this is not covered by the powertrain warranty. Called dealership to schedule a repair but the cost seems a bit high for just replacing wheel bearings. I also asked the parts department for just the parts so I can do it myself but the price mark up was way too high. I think they said $184. I'm finding these online for about $90 from GM. If anyone has done this repair and can share some pictures I would appreciate it.
