Q: Is a cv joint difficult to replace, on a 1997 Buick LeSabre?

asked by on

I bought four new tires on my 1997 Buick LeSabre Custom. I now noticed a vibration. Looked up possible causes, cv joint was mentioned. Just replaced rack and pinion and motor mount a month ago.

My car has 128000 miles.
My car has an automatic 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.
