What's up guys. I have a 2001 Nissan frontier desert runner. When I go over a small bump going slow or push on the rear suspension real hard, the left rear shock actually like..tops out, and makes a banging noise. I looked underneeth and I see that while just sitting, my trucks left rear shock is already like fully extended, while the right is not. I was wondering why it does this? My shocks are monroe matic's. Thanks.
