The Jeep YJ, sold as the Wrangler, replaced the much-loved but slower-selling Jeep CJ in 1986 and was built in Brampton, Ontario, Canada, until the plant closed on April 23, 1992. Production was then moved to Toledo, Ohio, using the same plant that produced the Willys Jeeps during World War II. American Motors Corporation (AMC) had designed the new Jeep to be more comfortable on-road in an attempt to attract more daily drivers. It was a new design with a wider track, slightly less ground clearance, and more comfort. The YJ still had leaf spring suspension similar to that of the CJ – however the springs were wider, and the YJs sported trackbars and swaybars for improved handling. Despite the new grille, the body is very similar to that of the CJ7, and it is interchangeable with some minor modifications. The YJ also was given a larger windshield over the CJ. The YJs are easily identifiable due to the rectangular headlights, disliked by some Jeep aficionados, and the fact that the wiper blades rest on the windshield giving this version a distinctive look. The blades rested on the windshield due to the now wider arc of the blades to clean the larger windshield. These two changes were later removed when the TJ changes came about in 1996.
