* Worn or broken suspension components: This is the most common cause. Worn springs, shocks, struts, ball joints, or bushings can all lead to a lowered front end.
* Air suspension issues (if equipped): Sprinter vans sometimes have air suspension. Leaks in the air springs or compressor problems can cause a loss of air pressure, resulting in a lowered front.
* Uneven tire pressure: Significantly lower tire pressure in the front tires compared to the rear will cause the front to sag.
* Overloading the front: Carrying a heavy load concentrated in the front of the van can temporarily lower the front end.
* Damaged frame or body: In severe cases, damage to the van's frame or body could cause a sag in the front.
To diagnose the problem, you should have a qualified mechanic inspect the van. They will be able to pinpoint the exact cause and recommend the appropriate repair.
