Precision Engineering for Extreme Duty:
Unimog Mechanical Servicing, Portal Axles & Drivetrain Upgrades
The Mercedes-Benz Unimog is renowned for its near-indestructible engineering, but keeping these specialized commercial machines operating reliably under heavy loads requires specialist tooling, proprietary torque specs, and in-depth mechanical know-how.
Whether maintaining a fleet of municipal utility Unimogs, an agricultural workhorse, or an overland expedition truck preparing to cross deserts, Goldstander delivers full mechanical servicing, component rebuilds, and performance upgrades for clients worldwide.
Specialist Portal Axle & Hub Maintenance
The portal axle hubs are the heart of the Unimog's mechanical prowess, but they are also subject to severe shear stresses and high thermal loads:
- Z Hub Oil Servicing & Seal Replacements: Regular inspection of portal hub seals and magnetic drain plugs prevents water contamination and premature bearing failure.
- Z Full Hub & Differential Rebuilds: We rebuild portal gear assemblies, ring and pinion gears, and pneumatic differential lock actuators using OEM-grade components.
- Z High-Speed (Fast-Axle) Ratio Conversions: For road-going expedition rigs, re-gearing portal and differential ratios allows comfortable 60–65 mph (100 km/h) highway cruising speeds at lower engine RPMs, dramatically cutting cab noise and fuel consumption.
Engine Diagnostics & Drivetrain Tuning
From legendary mechanical diesels (OM352, OM366A/LA) to modern electronically controlled OM904LA / OM934engines:
- Z Fuel Injection & Turbo Upgrades: Calibrating injection pumps and fitting intercooler upgrades to restore optimal torque across low-RPM rock crawling bands.
- Z Transmission & Pneumatics: Comprehensive servicing of UG3/40, UG3/65, and Telligent transmissions, including working gear groups, crawler gears, and compressed air systems.
- Z Braking & Hydro-Pneumatic Overhauls: Complete restoration of dual-circuit air-over-hydraulic brake systems, master cylinders, and proportioning valves.
Global Parts Sourcing & Mechanical Overhauls
Finding rare parts and specialized upgrade kits can be a major roadblock for Unimog owners outside continental Europe. Goldstander supplies and exports:
- Z Complete reconditioned engines, gearboxes, and portal axles
- Z Custom heavy-duty suspension, coils, and multi-stage shock absorbers
- Z International express shipping to workshops in the US, Europe, Australia, and worldwide
