 Definitions:
SAE Viscosity Rating: An SAE viscosity grade is used to specify the viscosity of engine oil.  These are specified with a dual SAE viscosity grade that indicates the cold-to-hot temperature viscosity range.  Example SAE 10W-30 = multi-grade engine oil.

Lubricants and Greases: Lubricating grease is rated for quality and usage by the NLGI.  All approved products have the NLGI symbol on the label.  At the bottom NLGI symbol is the usage and quality identification letters.  Wheel bearing lubricant is identified by the letter “G”. Chassis lubricant is identified by the letter “L”.  The letter following the usage letter indicates the quality of the lubricant.  Examples; GC = Wheel Bearings, LB = Chassis Lubrication, and GC-LB = Chassis and Wheel Bearings.

 SAE: Society of Automotive Engineers

 NLGI: National Lubricating Grease Institute

 API: American Petroleum Institute

Common Sense and Safety should always be observed when working on your vehicle or doing modifications. Jackstands, wheel blocks, disconnecting the battery are a few of the basic safety precautions that should be used and may not be mentioned in the write ups on this site. You are responsible for your own installation, these write ups are a helpful guideline and should not be taken as an official installation instruction. My write up may be different from the kits currently out there, so alwasy double check the manufacturers installation instructions when installing anything. I try to keep the site up to date with changes that have occured as I discover them, but may not have the latest unless someone lets me know. If you feel that an install is above your capabilities after reading my write ups, I recommend getting together with a club and getting some help. Only a few times have I needed to employe some actual help from a shop to get something done. Usually welding or A/C work. While I have spent many years working on mechanical systems, I am not an expert, nor do I pretend to be one. I hope these write ups have been useful to you.
