Transfer Case
Repair & Rebuild
All BMW xDrive Models. Factory-Level Diagnostics. Done Right.
BMW xDrive Transfer Cases
Are Our Specialty.
The BMW xDrive transfer case (ATC — Active Transfer Case) is one of the most complex and failure-prone components on all-wheel-drive BMW models. When it goes, you get vibrations, drivetrain faults, and a car that no longer puts power where it needs to go.
We specialize in full transfer case rebuilds and repairs across every BMW xDrive platform — from the E70 X5 to the latest G-series M models. Using factory ISTA diagnostics and OEM-spec components, we fix it right the first time.
Factory ISTA Diagnostics
We use the same diagnostic software BMW dealers use — so we know exactly what failed, not just what the generic scanner says.
xDrive Recalibration Included
After every rebuild or replacement, we recalibrate the entire xDrive system via ISTA to ensure proper AWD engagement and torque distribution.
Rebuild or Replace — Honest Assessment
We tell you what actually makes sense for your car and budget. No unnecessary upselling — just the right fix.
What's on That Magnet?
That buildup on the drain plug magnet tells the whole story. What you're seeing is a combination of:
- Fine metallic fines — shed from worn bearings grinding against races
- Clutch pack friction material — carbon and fiber debris from a slipping or burnt clutch
- Gear wear particles — microscopic steel from gear tooth contact under load
- Seal degradation residue — rubber and polymer fragments from failing input/output seals
A magnet this loaded means the transfer case has been failing for a while — and the fluid has been circulating all of that debris through every bearing and seal.
Is Your xDrive Telling
You Something?
These are the most common signs your BMW transfer case needs attention. Don't ignore them — they get worse fast.
How We Fix It,
Step by Step.
Full ISTA Diagnostic
We pull all fault codes and run a complete xDrive system test to pinpoint exactly what's failed — transfer case, ATC, or related components.
Teardown & Inspection
The transfer case is removed and fully disassembled. Every bearing, seal, clutch pack, and gear is inspected for wear and damage.
Rebuild or Replace
Depending on condition, we rebuild with OEM-spec components or source a quality replacement unit — always the right call for your specific model.
Reinstall & Calibrate
Reinstalled with fresh fluid, all mounts torqued to spec, and the xDrive system recalibrated via ISTA to ensure proper AWD engagement.
Road Test & Verify
Full road test under load to confirm smooth power delivery, zero vibration, and no fault codes before the car goes back to you.
OEM-Spec Parts,
Every Single Time.
Before reassembly, every bearing, seal, and clutch pack is laid out and inspected. Worn or damaged components are replaced with OEM-spec parts — no reused seals, no shortcuts.
- All bearings replaced as a set
- New seals — input, output & actuator
- Clutch pack inspected & replaced
- Fresh OEM-spec transfer case fluid
