"M.R.279 Jeep YJ/Wrangler" This is the original shop manual used by Jeep dealer mechanics throughout the U.S. and Canada. You will find step-by-step illustrated service instructions for engines, electrical, clutch, gearboxes, automatic transmission, steering & front axle, rear axle, suspension, brake system, heating & air conditioning, and accessories. Includes special tools compiled at the beginning of each section, specifications, towing instructions, drive line lubrication, and conversion tables. 988 pages with exploded view illustrations, troubleshooting guides, trouble code interpretations, and more. Jeep originally published the book in mid 1986, then issued updates in 1987 and 1988 - this manual has that original publication plus the updates inside it. Look for I.S. notes (service bulletins) in the back of the book for revised 1987 & 1988 information. This is the only way Jeep made a shop manual in these years. Covers all mid-86 through 1988 Wranglers, including Laredo, S, and Sahara. Buy now for this original manual from Jeep.
