hey guys. i have an 06 titan xe 2x4. i have about 35000 miles on it now and ive noticed sum slack in my drivetrain somewhere.. its actually been doing it for a long time. but it seems to be getting worse. you can feel it when you first take off and when you come to a stop... its kinda hard to explain but it almost feels like there is slack in the ring and pinion or smthing.... any help or info would be much apreciated.....
