Where can i put grease in my 91 Nissan Sentra?

In a 1991 Nissan Sentra, you can apply grease to several key areas to maintain its performance. Common locations include the ball joints, tie rod ends, and the u-joints if your vehicle has them. For those with grease fittings, you can use a grease gun to apply the lubricant. Always refer to your vehicle's service manual for specific lubrication points and intervals.
