Subaru CV Shaft Repairs and Replacement
Subaru Constant Velocity (CV) joints and shafts are the last link in the drive train between engine and wheels. Being an all-wheel drive system, with both front and rear drive shafts and CV joints, Subaru CV joints have to endure more load and stress and this results in more frequent failures. The font wheels perform both driving and steering and therefore carry the most load, particularly the outer CV joints, and present the most serious safety issues. Given that new genuine Subaru CV shafts are upward of $1000, it has also created a lucrative market for Chinese manufacturers, who supply new parts at much lower prices. However, the Chinese shafts are notoriously under-engineered, and can fail under load resulting in a very dangerous situation. It doesn't pay to skimp on safety.
ADS can offer three options when the time comes to repair or replace your CV shafts:
Option 1: If your existing CV joint is still serviceable, and the problem is only a torn or leaking CV boot, we can fit a repair kit, including new rubber boot, grease and clamp. This is by far the least expensive option and will greatly extend the life of your drive axle.
Option 2: We can supply a fully reconditioned ADS drive shaft, with all new components and certified used shaft. This is the most reliable option, with our product being at minimum equal to the OEM unit. In in some models we may be able to supply a superior, revised unit.
Option 3: We can supply and install a brand new OEM Subaru drive axle. This is, as noted a very expensive option but may be preferred by some owners who like to replace only with new parts. We will not supply or fit the cheap knock-off units.
How do I know when my drive shafts or CV joints need repair?
- You may hear a clunking or knocking sound from the front of your Subaru when you are making a tight turn. This usually indicates worn outer CV joints. If ignored, this can become a critical safety issue. In this case, option two or option three would be indicated.
- You may also notice a knocking sound/vibration while driving in a straight line. This is the most difficult problem to diagnose and is usually a result of a worn front Inner CV joint. Option two or three is also indicated here.
- You may notice a smell of burning grease. This is because the rubber CV boot is torn and grease is leaking onto the hot exhaust. If the CV joints are still serviceable, option 1 may be indicated.
