Having trouble with service dept of local dealer regarding driver's side axle as it enters the drivers side transmission case. Dealer tells me it's normal for this amount of "play" - they say it is designed this way for going over bumps - don't believe them at all as I know that the cv joint handles the bumps. I know that the shaft and the bearing are a very precise fit and there should not be any play. There is a grinding noise when slowing down and a fluttering/clicking noise when I pop the vehicle in neutral at about 50 mph (this is probably the splines on the end of the shaft not mating into the differential correctly - misaligned - because the bearing has failed). Dealer keeps telling us it's either our brakes or tires. They have checked the brakes 4 times already and found nothing but they do acknowledge the grinding noise is still there. This vehicle is dangerous to drive in this condition as the symptoms keep getting worse. It has been at the dealer's service department this time for 6 days already. The vehicle is still under the 100,000 kia drive train warranty (vehicle has 91,000 miles on it). I have sent the video along with this same note to NHTSA. Webmaster@dot. Gov. Would like your opinion of what the amount of movement signifies on the axle as shown in the video - pretty sure it is evidence of a failed bearing (which has led to further damage within to the differential and shaft splines). Thank you!.
