Where do I check the transfer case fluid level?

The diagram shows a 'Check Fluid Level Transfer Case' point on the transfer case behind the transmission, which is also the drain-and-refill location.

What tool note is given for greasing the universal joints?

The diagram says to use a rounded-nose adapter for flush-type fittings when servicing the universal joint plugs.

Which maintenance items must be done daily when operating in deep water?

Items marked with an asterisk: repack front wheel bearings and free-running hubs (both sides), drain the transmission, drain and refill the transfer case, and drain the rear differential.

Where is the rear axle lubricant checked?

At the differential plug on the rear axle — 'Differential Plug – Check Rear Axle Lubricant Level,' which is also the drain point.

What is shown in the 'Steering - Brakes - Clutch' inset?

The steering gear (plug), the clutch release equalizer, and the brake master cylinder.

This document is a chassis lubrication and maintenance diagram showing an overhead (bottom/plan) view of a 4-wheel-drive truck chassis. Callouts identify all service and lubrication points on the chassis: grease fittings on the front axle/steering area, power steering, front axle lubricant level check, front wheel bearing and free-running hub repacking (both sides), universal joint spline fittings (slip yokes) on both driveshafts, universal joint plugs (noting to use a rounded-nose adapter for flush-type fittings), the transmission fill/level plug and drain, the transfer case fluid level check with drain-and-refill point, and the rear differential plug for checking rear axle lubricant level and draining. Two inset drawings show the automatic transmission dipstick location and a "Steering - Brakes - Clutch" panel identifying the steering gear plug, clutch release equalizer, and brake master cylinder reservoirs. Items marked with an asterisk (drain points, wheel bearing repack) carry the note "daily when operating in deep water," indicating an increased service frequency for deep-water operation. A reader can learn where every fluid check, drain, and grease point is located on the chassis and which items require daily attention after deep-water use. The document itself is undated and does not state a specific make, model, or year.
