Description
Send full torque to both axle shafts when traction is uneven
Yukon Gear & Axle YGLTLC-30 is a mechanical Grizzly Locker for the Toyota 9.5-inch Land Cruiser axle with 30-spline shafts. Selection depends on the axle, spline count, gear ratio, bearing journal, and installation notes rather than a broad year-make-model list.
Key Features
- Mechanical positive-locking differential
- Toyota 9.5-inch Land Cruiser axle application
- 30-spline axle-shaft interface
- Designed for 4.56-and-up gear ratios
- 8620 alloy internals
- Assembled in the USA
- No broad year-make-model fitment applies

About Yukon Gear & Axle
Yukon Gear & Axle supplies ring-and-pinion sets, axles, bearings, and traction devices for specific axle families. Correct housing identification, spline count, ratio break, bearings, clearances, and professional setup are essential for differential service.
Related Parts
- No internal gears, bearings, seals, or installation kit is linked because every companion component must match the exact Toyota 9.5-inch axle, ratio, journal, and housing condition.
FAQ
What is the YGLTLC-30?It is a mechanical Grizzly Locker for the specified Toyota 9.5-inch Land Cruiser axle with 30-spline shafts.
Does it fit by vehicle year alone?No. The axle family, spline count, ratio, bearing journals, and installation notes control compatibility.
What gear ratio does it require?The verified application is for 4.56-and-up gear ratios.
What bearing journals does it use?The verified journal diameter is 45 mm, with the referenced bearing set shown in the specifications.
Is it selectable by the driver?No. This is a mechanical automatic locker, not an air- or electrically-selectable differential.
Is professional installation recommended?Yes. Differential bearing preload, backlash, pattern, cross-pin clearance, and ring-gear clearance require proper tools and experience.
Are bearings and gears included?Only the locker components in the sealed package are included. Bearings, gears, oil, seals, and installation parts are selected separately.
What should be checked before use?Verify backlash, contact pattern, bearing preload, fastener torque, cross-pin and ring-gear clearance, lubricant, leaks, and normal differentiation behavior.
Installation Instructions
- Identify the Toyota 9.5-inch Land Cruiser axle and verify 30 splines, 4.56-and-up gearing, 45 mm journals, and the required bearing references.
- Measure the existing gear setup and inspect the housing, shafts, ring and pinion, bearings, caps, and fasteners before disassembly.
- Follow the current Yukon and axle-service procedures for carrier removal, bearing installation, ring-gear transfer, and any documented cross-pin clearance work.
- Install the locker with the correct bearings and hardware, preserving bearing-cap position and orientation.
- Set bearing preload, backlash, and gear contact pattern with calibrated tools, then torque every fastener to the current specification.
- Fill with the specified lubricant, verify differentiation and lockup behavior, inspect for leaks or noise, and follow the documented break-in and recheck procedure.
