My 2017 ranger xp 1000 3 seater is driving me nuts. It has a rattle type knock noise from the rear end under light load and slow speeds. I have been a toyota mechanic for 20 years and i can't find this darn noise. I have put my chassis ears on the left rear hub and can hear coming from there but the bearing is tight. That and bearing get worse with speed and this goes away and is not constant. That and when you get after it on the roads and put it under a load it goes away. So something is loose but with only 2200 miles i cant see a diff having a backlash problem. Its almost like it is slipping in gear a bit but its not a gear slipping sound. Its a back and forth metal sound like the back lash is to loose. So any advise would be great if y'all have the time I'd appreciate it.
