Overview
The ZF 5838.117.024 REAR AXLE HOUS. is a critical structural component engineered to encase and protect the differential and final drive gearset within ZF heavy-duty transmissions. This OEM genuine part, identified by SKU 5838.117.024, serves as the primary load-bearing shell for the rear axle assembly in construction machinery, ensuring precise alignment of internal rotating elements under extreme torque and shock loads. By maintaining rigid geometric integrity, this housing prevents contamination ingress and lubricant egress, directly supporting the longevity of the entire drivetrain system.
Symptoms of Failure
- Visible oil seepage from axle housing seals: When the 5838.117.024 housing develops micro-fractures or warpage, lubricant escapes past the seals, leaving wet patches on the axle tube and under the machine during operation.
- Abnormal whining or grinding noise during turns: A compromised housing allows misalignment of the 5838109010: DIFFERENTIAL carrier, causing gear tooth interference that produces distinct metallic sounds under load.
- Increased backlash in the driveline: Structural fatigue in the housing bore distorts the mounting points for the 0750117075: TAPER ROLLER BEARING, leading to excessive play and delayed engagement when shifting between forward and reverse.
- Contaminated gear oil with metallic debris: Cracks in the housing allow abrasive particles to enter the lubricant circuit, accelerating wear on the 2093209023: DIFFERENTIAL assembly and requiring immediate inspection of the 5838300626: DIFFERENTIAL HOUSING.

Compatibility
This rear axle housing is specifically designed for ZF WG series powershift transmissions commonly deployed in wheel loaders, graders, and heavy forklifts. It directly fits the WG180, WG200, and WG210 transmission models. The housing also integrates with the WG150 series when used with the appropriate 5838300633: AXLE adapter kit. Always verify the axle flange pattern matches your specific transmission variant before installation.

Frequently Asked Questions
Q: Can the 5838.117.024 housing be repaired if it has a hairline crack?
A: No. Due to the high stress concentrations and the risk of catastrophic failure, ZF mandates replacement of any cracked housing. Welding or epoxy repairs are not approved for this structural component.
Q: What torque specification should I use for the housing bolts?
A: For the eight M16 bolts securing this housing to the transmission, apply 210 Nm (155 ft-lbs) in a cross-tightening sequence. Always use new lock washers and lubricate threads with medium-strength threadlocker.
Q: Does this part include the differential carrier bearings?
A: No. The 5838.117.024 is supplied as a bare housing. You must order the 0750117075: TAPER ROLLER BEARING and associated shims separately to complete the assembly.
