I thought it was my tires, so I just replaced them and the noise is still there. Fairly loud and noticeable thumping or clunking noise while driving, especially noticeable at slower speeds and especially on turns. Drives fine, but this noise concerns me. Started about 2 weeks ago.
My car has 84000 miles.
My car has an automatic transmission.
This is a sign of worn or failing CV joints. All front-wheel drive cars have Constant Velocity joints or CV joints on both ends of the drive shafts (half shafts). Inner CV joints connect the drive shafts to the transmission, while the outer CV joints connect the drive shafts to the wheels. Many rear-wheel drive and four-wheel drive cars as well as trucks also have CV joints. The CV joints are needed to transfer the torque from the transmission to the drive wheels at a constant speed, while accommodating the up-and-down motion of the suspension. In front-wheel drive cars, CV joints deliver the torque to the front wheels during turns.
There are two most commonly used types of CV joints: a ball-type and a tripod-type. In front-wheel drive cars, ball-type CV joints are used on the outer side of the drive shafts (outer CV joints), while the tripod-type CV joints mostly used on the inner side (inner CV joints). 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.
