Q: Clunking while decelerating

asked by on December 10, 2016

Hi, guys. I have a 1998 Nissan 200sx se and every time I decelerate, or let off the accelerator, it starts clunking... badly Can someone tell me what the problem "could be?" thank you.

My car has 121400 miles.
My car has a manual transmission.

This is a common sign of a failing CV joint. A CV (Constant Velocity) joint is a shaft that connects the transmission to the wheels, essentially transferring the power from the drive train directly to the wheels. The CV joint is packed with a special grease and sealed tight with the rubber or plastic boot, that is held in place with two clamps. The most common problem with the CV joints is when the protective boot cracks or gets damaged. Once this happens, the grease comes out and moisture and dirt get in, causing the CV joint to wear faster and eventually fail due to lack of lubrication and corrosion. When the CV joint becomes damaged or worn, you may hear a clicking or popping sound coming from this area. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your CV joints.
