Four-wheel drive SUVs and off-road vehicles, such as a Jeep or Hummer, are engineered to withstand rugged conditions. However, this means that you need to be careful to maintain these vehicles, often more diligently than other automobiles. And, you need to be aware of Factory Recommended Maintenance or recall issues for your particular 4-wheel drive model.
For example, off-road “wading” or “rock climbing” can cause under-vehicle issues such as a rusting chassis, sagging springs or poor shock absorbency.
If you are considering purchasing a used 4×4 vehicle or are unsure of the maintenance issues that you can expect when driving an off-road vehicle, then read “Four Wheel Drives – Faults & Problems.”
Of course you can always count on your local St. Louis AAMCO Center for expert advice on maintaining your 4×4 vehicle – either after a heavy snow or a fall camping trip. The 4×4 services St. Louis AAMCO Centers offer include:
- Draining and refilling the Transfer Case with OEM-specified fluid
