Drive Shaft Buying Guide
Last updated: 24 April 2026
The drive shaft (also called a half shaft or CV axle) transmits engine torque from the gearbox differential to the driven wheels. Each shaft has CV joints at both ends that allow the shaft to flex with suspension movement and steering angle. At CarParts247 we stock drive shafts from SKF, GKN, and Lobro.
Drive shaft failure symptoms
CV joint failure is the most common drive shaft problem. The rubber boot splits first, allowing grease to escape and dirt to enter. Once contaminated, the joint wears rapidly.
- Clicking or popping noise when turning — outer CV joint wear
- Vibration at speed — worn inner CV joint or bent shaft
- Torn or leaking CV boot — grease visible on inner wheel arch
- Knocking or clunking on acceleration from standstill
- ABS fault — a damaged reluctor ring on the shaft triggers ABS warnings
Replacement options
If caught early, a split boot can be replaced without changing the joint. Once the joint itself is damaged, replacing the complete drive shaft is more cost-effective and reliable than rebuilding individual joints.
- Complete shaft replacement is faster and more reliable than joint-only repair
- Always replace the hub nut — most are torque-to-yield and single-use
- Check the gearbox oil seal where the shaft enters the transmission
- Torque the hub nut to specification — this is critical for bearing preload
- A wheel alignment may be advisable after drive shaft work

Frequently Asked Questions
Can I drive with a clicking CV joint?
Short distances at low speed, yes. But a worn CV joint can break completely without warning, leaving you stranded and potentially damaging the gearbox. Replace promptly.
Is it better to replace the whole shaft or just the boot?
If the boot is split but the joint still feels smooth with no play, a boot replacement may suffice. If there is any clicking, grinding, or play, replace the complete shaft.
Why does my car click when turning?
A clicking noise on full lock is the classic symptom of a worn outer CV joint. The joint has lost its grease and the ball bearings are wearing against the races.
How long does a drive shaft last?
Drive shafts can last the life of the vehicle if the boots remain intact. Once a boot splits, the exposed joint typically fails within a few thousand miles.
