Since many of us here in Colorado drive front-wheel drive vehicles, it’s important that we keep an eye on the CV joints to make sure they aren’t in need of repair.  Front-wheel and all-wheel drive vehicles transfer the power from the transmission to the wheels through a drive axle assembly.  These drive axles have constant-velocity  (CV)  joints at each end.

A CV joint is a group of bearings and cages that allow the axle to rotate and deliver power at different angles  so that the axle can change its length as it moves up and down.  The CV joints are protected by rubber boots that keep dirt and contaminants out and a protective layer of lubricant in.

Just like everything else in life, these rubber boots can crack or tear over time.  If moisture and dirt get inside a CV joint and the lubricant leaks out, due to normal wear and tear, there is a greater potential for CV joint failure.

The signs of possible CV joint failure are clicking or crackling sounds while turning, clunking sound during accelerating or sudden deceleration.  You might also notice front-end vibrations.

If you haven’t noticed anything unusual you should still have the CV joints checked routinely to keep you ahead of the repairs but if you think your vehicle is showing any of these signs  give us a call at 303-691-2760 or come in and see us before the damage becomes more costly to repair.
