Transfer case 4x4 service for your Sprinter covers fluid changes, actuator faults, and noise on 4x4 and AWD vans that work jobsites and backroads. We drain and refill the transfer case with the correct fluid, test the shift actuator and mode selection with Xentry, and inspect the seals and output for leaks, so four-wheel drive engages when a Riverside crew needs it.


## What this includes
- Transfer case fluid drain and refill to spec
- Xentry test of the 4x4 shift actuator and mode selection
- Inspection of the actuator motor and wiring
- Seal and output flange leak inspection
- Check of engagement in 4x4 low and high
- Fault clear and road test

## Who it is for
- Your 4x4 or AWD Sprinter will not engage properly
- You hear noise or feel binding from the transfer case
- The transfer case fluid is overdue
- A shift actuator or mode fault is stored

## Pricing
Mechanical labor runs $260 per hour; a fluid service versus an actuator replacement sets the range, all set in writing after inspection.

## FAQ
### How often should the transfer case fluid change?
Every 40,000 to 60,000 miles is a reasonable target, sooner if you run dirt or sand around the Inland Empire. Fresh fluid protects the gears and chain.

### Why will my 4x4 not engage?
Often a failed shift actuator, low fluid, or a mode fault. We test the actuator and mode selection with Xentry to find why it will not shift.

### Is a noise from the transfer case serious?
It can be. Whining or binding can mean low fluid or internal wear. We inspect and service it before a small issue turns costly.

### Do you service both 4x4 and AWD Sprinters?
Yes. We service the fluid and actuators on 4x4 and all-wheel-drive Sprinters and confirm engagement in each mode afterward.
