1984-1989 Toyota 4Runner Manual Factory Service Manual

• Covers 1984–1989 Toyota 4Runner and associated Pickup, Van, and luxury models utilizing G, R, and W-series manual transmissions
• Original OEM publication, copyright 2008 Mitchell Repair Information Co., LLC
• Contains 57 exploded-view diagrams and 12 detailed torque specification tables for internal transmission components
• This 1987-origin service reference details factory-authorized procedures for manual transmission overhaul on the specified driveline variants

Drivetrain and Transmission Walkthrough

This manual delivers the technical documentation required to overhaul G52, G53, R150 series, and W-series manual transmissions. You will find exact details on the disassembly and reassembly of the intermediate plate, input and output shafts, and shift fork assemblies. The text clearly outlines critical clearance measurements for gear thrust and lateral movement. Transmission teardowns involve heavy components and significant spring pressures. Always properly support the gearbox on a rated transmission jack and follow standard shop safety practices before removing the bell housing.

Beyond the physical teardown, additional sections cover lubrication and adjustment procedures for the 1983–1994 vehicle range. This includes specific drivetrain requirements paired with the 22R-E and 22R-TE engines. The data is organized intuitively by assembly. Clear exploded views for shifter assemblies and synchronizer rings make it easy to identify the exact snap rings, bearings, and hub sleeves required for precise component fitment.

Specification and Reference Data

Finding accurate internal clearances is often the most time-consuming part of a rebuild. This documentation solves that problem by providing extensive tables for input shaft and countershaft snap ring thicknesses. These dimensions are vital for achieving minimum axial play during reassembly.

Torque values are mapped out clearly for quick reference on the shop floor. For example, clutch housing bolts are listed at 27 ft. lbs. (37 Nm), while shifter retainer bolts require 13 ft. lbs. (18 Nm). You also get reference values for gear-to-shaft oil clearance in both inches and millimeters. Ultimately, this provides the official 1984–1989 service information documenting essential chassis and transmission specifications for R and W-series driveline builds.
