Quick Answer

Infiniti published service information for fluid leaking from the right-front side of the transfer assembly on applicable AWD JX35 and QX60 vehicles. The procedure warns against automatically replacing the complete transfer assembly and describes resealing when the specified leak is confirmed. Other leak locations and internal damage require a different repair.

What Does the QX60 Transfer Assembly Do?

On an all-wheel-drive QX60, the transfer assembly routes power from the transaxle toward the rear driveline. Front-wheel-drive versions do not have the same AWD transfer hardware, so this topic begins by confirming the drivetrain.

The transfer assembly and CVT sit close together on earlier vehicles. Fluid can travel across housings and shields while the car is moving, making the wettest visible point an unreliable diagnosis until the area is cleaned and rechecked.

What Are Possible Transfer-Case Leak Symptoms?

Owners may find drops on the driveway, oily residue near the passenger side of the drivetrain, or a burning-fluid odor when leakage reaches a hot surface. A low fluid level can eventually contribute to whining, grinding, vibration, or AWD trouble.

Many leaks are found during an oil change before the vehicle behaves differently. Early inspection is valuable because the repair may be smaller before fluid loss damages bearings or gears.

Why the Exact Leak Location Matters

Infiniti service information for applicable JX35 and QX60 vehicles identifies a leak from the right-side drive-shaft area of the transfer assembly and provides a resealing procedure. It specifically instructs technicians not to replace the transfer assembly when that documented sealing condition is the confirmed cause.

That guidance does not apply to a cracked housing, internal noise, contamination, or a leak from another seal. The vehicle and leak location must match the procedure before the reseal path is chosen.

How Is the Fluid Source Confirmed?

The technician identifies the fluid type, checks each relevant level, cleans the area, and inspects after a road test or monitored period. Dye may help when several fluids are close in color or the leak is slow.

  • Engine oil can travel rearward from above.
  • CVT fluid can appear near the transfer area.
  • Transfer oil has its own source and specification.
  • Axle, cooler-line, or case seals can wet adjacent surfaces.

Replacing the most visible seal without tracing the path can leave the actual leak untouched.

Does a Transfer Leak Require Complete Replacement?

No single answer fits every leak. A specified sealing condition may be repairable without replacing the unit. A damaged case, worn internal components, severe noise, metal contamination, or operation with inadequate fluid can require more extensive work.

A useful estimate should identify the source, fluid condition, repair procedure, and whether the assembly operates quietly. It should also explain any related axle seals, mounts, or driveline parts found during inspection.

QX60 AWD Leak Diagnosis Near Metro Atlanta

Fastlane provides Infiniti drivetrain and transmission inspection in Hiram, Smyrna, and Woodstock. Avoid pressure-washing the leak immediately before the appointment; the pattern may help the technician locate its starting point.

Schedule online through the Infiniti service page or learn more about Fastlane's drivetrain service. Prompt inspection can separate a resealable leak from a condition that has already affected the unit.
