DIY Mechanic Check: Before Visiting a Shop
- Visual Inspection: If you hear a grinding/whining noise at 35–45 mph, switch briefly into 4Hi. If the noise instantly vanishes, it is the driver-side diff needle bearing.
- Check Fluid Levels: Verify engine oil level, coolant level in the reservoir, and transmission/power steering fluid condition.
- Replicate Under Control: Note whether the sound happens when moving or stationary, and if turning the steering wheel alters the pitch.
