DIY Mechanic Check: Before Visiting a Shop
- Visual Inspection: If the vehicle emits a loud click every time you step on or let off the accelerator pedal, the rear wheel hub axle splines need lubrication with Molykote paste.
- 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.
