Complete chassis greasing should include an inspection of all rubber suspension bushings, as well as proper greasing of the front suspension upper and lower ball joints, control arm bushings and especially the driveshaft universal joints. To provide correct operation, the chassis should be greased with every oil and filter change or 7,500 miles (12,070 km). Use a standard, good quality lithium-base chassis grease (NLGI No. 2).
To lubricate the chassis of your Toyota truck, use a cartridge-type grease gun and good quality lithium-base grease. Clean the grease fitting first, to avoid pushing dirt into the joint. Push the nozzle of the grease gun onto the fitting and, while applying pressure, force the new grease into the fitting. Force sufficient grease into the fitting to cause some old grease to be expelled (called purging the joint) and until you see fresh grease begin to run out of the joint. Wipe off expelled grease; keep the fittings and joints free of excess grease. Take care to keep chassis grease off rubber components such as tires and flexible brake lines.
Not all areas can be greased. Some steering and suspension components are lubricated at the factory and use permanently sealed joints; no lubrication is necessary.
Four-wheel drive vehicles have several lubrication points within the driveshaft and driveline. Some of these fittings are tucked into hard to see places; make certain each one is accounted for.
PARKING BRAKE LINKAGE
At yearly intervals or whenever binding is noticeable in the parking brake linkage, lubricate the cable guides, levers and linkage with a suitable chassis grease.
