1998 Acura CL CV Joint Replacement Cost

A CV joint should last the lifetime of the vehicle. Unfortunately, it is not uncommon for an axle to fail. If a CV joint boot cracks or tears, it is only a matter of time before the joint wears out. If a boot is compromised, it can be replaced. If the problem is recognized before other symptoms happen (clicking or clunking sounds when driving), the life of the axle can be prolonged. Replacement of the joints and boots on a CV axle requires that the entire assembly must be removed from the vehicle and disassembled. Because of this labor-intensive approach - and because there is no guarantee how long the joint may last after being compromised - many owners choose to have the entire assembly replaced instead.

To diagnose a failing CV joint, a technician will remove the wheel and inspect the CV joint boots for wear and cracks. If the boots are damaged, replacement is indicated. If no visible signs of wear appear, it may be necessary for the technician to take the vehicle for a test drive to evaluate the symptoms. Sometimes a damaged CV joint is noticed during other repairs or inspections.

To replace a CV joint, a technician will need access to vehicle-specific repair information. The means of connection between the axle and the transmission differs from one model to the next. For instance, some axles feature a hidden snap ring that retains the axle inside the transmission. The technician will lift and support the vehicle and pull the wheel and tire. The axle nut is removed and the lower control arm ball joint is disconnected so that the wheel hub and steering knuckle can be moved out of the way. The outer end of the axle is pushed through the wheel hub to release it from the front suspension and steering. The axle assembly is supported to avoid damage to the oil seal between the transmission and the axle, and the axle is disconnected from the transmission. Once outside the vehicle, the axle is disassembled, fitted with new boots and new joints, and packed with grease. The rebuilt axle assembly is fitted into place, and the front suspension and steering components are reinstalled. Finally, the hardware is torqued to manufacturer's specifications and any lost fluid is replaced. On some vehicles, additional disassembly of suspension parts might be necessary.

RepairPal recommends the use of new replacement CV axle shafts. It is increasingly economical to do so, and new axle assemblies are more reliable than rebuilt units. In addition, there is little advantage to replacing the CV joint boots. The cost of repair is nearly as much as the cost of a new axle, and there is no guarantee that permanent damage has not already been done to the joint.

There is no set-in-stone timetable for the lifespan of a CV joint once symptoms of wear appear. Road conditions, aggressive driving, weather, and the like, all play roles in the breakdown of the CV joint once a boot has broken open. Because the results of a failed axle are severe, replacement should be considered as soon as possible.

Only someone with considerable experience in replacing suspension components - and access to vehicle-specific repair information - should attempt the replacement or rebuild of a CV axle assembly. Care must be exercised to prevent damage to the transmission or steering and suspension components, as well as to the new axle assembly.
