Chassis Lubrication
General lubrication includes lubricating all the grease fittings in the drivetrain, front and rear suspensions, power steering, and front axle, using a grease gun.
Grease the chassis every 15,000 miles (24,000 km). However, if the vehicle is in a demanding application or running in a dirty or corrosive atmosphere, adjust the lubrication intervals to reflect heavy-duty use. For example, if driven in heavy stop-and-go traffic with a lot of maneuvering, the lubrication intervals should be every 10,000 miles (16,000 km) or less.
All lubricating points are found on the chassis lubrication chart on the next page.
Lubricating Grease
Use grease with a lithium base with EP additives and a consistency of NLGI No. 2.
The No. 2 consistency is suitable for most temperatures. Use NLGI No. 1 or No. 0 for extremely low temperatures.
Care should be taken not to use any grease other than one with EP additives for the driveshaft. Do not use any solid lubricants,such as graphite, copper or molybdenum disulfide.
Lubrication Procedure
Make sure the grease fittings are cleaned off before filling grease. Dirt on the fitting that is not cleaned off is pushed into the part together with the new grease. Always fill grease to the point where old grease and contaminants are forced out from the part and only new grease comes out. If new grease cannot be filled so old grease is flushed out, the part needs to be checked for problems. If a fitting does not accept
lubrication due to damage or internal stoppage, replace it with a new fitting.

NOTE! Think of greasing the same way as an oil change. All old grease needs to come out and replaced with new grease.
Where rubber or plastic parts are involved,do not heat part for better grease application.
Remove excess grease from fittings, shackles and other surfaces.
NOTE! Always grease a Volvo front axle with the wheels on the ground.

Lubrication Chart Notes
1 Add if necessary. Only use pre-mixed clean water and antifreeze in a 50/50 mix.
Add only the same type antifreeze,that is: extended life or standard.
2 Check the fluid in the reservoir with the dipstick. Add if necessary. Use
ATF Dexron® III. Change fluid every 150,000 miles (240,000 km). Change filter every year.
3 There is no set change interval.Change the oil (or grease) only in connection with work on the hub or if dirt is found in the lubrication. Use motor oil SAE 30.
4 Change the oil according to the schedule on page 61.
5 Check that the fluid is at the correct level. If needed, add fluid using brake fluid DOT 4. Fluid should be replaced every 2 years.
6 Use a mineral or synthetic oil. Check oil level periodically. Level should be to the bottom of the inspection hole.
See page 166 for oil types.
7 Check the oil level in the rear axles.
The level should be level with the inspection hole. Add if necessary.
8 Use a lithium based grease with specification API NLGI No. 2. When lubricating the springs, lift the axle off of the floor, suspend the frame with axle stands and lower the axle. The spring bushings are now in the position where grease can be added to the contact surfaces.
9 Use a lithium based grease with specification API NLGI No. 2. Use liberally in the slack adjuster. Make sure the grease purges through the seal on the brake cam.
NOTE! If the brake cam seal does not purge, make sure the inner seal does not purge into the brake drum and onto the brake linings.
10 Use a lithium based grease with specification API NLGI No. 2. Only use a hand operated grease gun. The high pressure from an air operated grease gun will damage the seal.
11 Use a lithium based grease with specification API NLGI No. 2.
NOTE! Always grease a Volvo front axle with the wheels on the ground.
NOTE! To grease non-Volvo axles,they are typically greased with the wheels on the ground. Consult with the axle manufacturer for the latest recommendation.
