Took my truck in to fix a front wheel bearing, and they fixed other things apparently. Or tried to. Got it back with no 4 wheel drive. What did they do?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If you took your Dakota in for a wheel bearing replacement and ended up with no 4WD, it’s likely they tinkered with the axle or transfer case components—both of which could impact 4WD function if disturbed. On a 2000 Dakota, the 4WD actuator is vacuum-operated, so if they accidentally left a line disconnected or bumped the actuator, it could knock out your 4WD. A quick inspection of vacuum lines or connectors around the transfer case might reveal the culprit.
