Cardone 66-2004 CV Axle Assembly - Front Left

Cardone CV Axle Assembly for Ford and Mercury

Cardone CV Axle Assembly 66-2004 is a new front left driveline replacement built for select Ford Escort, Ford Tempo, Mercury Topaz, and Mercury Lynx applications. It is engineered to address common CV axle failure points with attention to boot durability, shaft straightness, and seal performance.

Key Features

• Fits front left applications on select 1983-1990 Ford and Mercury vehicles
• ABS ring included for vehicles equipped with ABS monitoring
• New axle retaining nut supplied for installation service
• Neoprene boots use added bellows where needed to reduce stress and ozone cracking
• Boot clamps are pneumatically crimped for a tight seal at the boot and housing
• High-temperature, high-torque grease is used for long-term joint lubrication
• Transmission seal diameter is precision-machined after heat treatment for proper seal life
• Shafts are individually verified for straightness to help reduce vibration

Detailed Description

Cardone 66-2004 is part of the Cardone CV Axle Assembly line, a product line focused on correcting the causes of repeat CV failure rather than simply replacing worn parts. For this application, the axle is built with a splined 23-count input shaft and a splined 26-count output shaft, plus a stake-style spindle nut thread size of M20 x 1.5. The compressed length measures 22.244 inches, and the assembly includes the complete axle and instruction sheet.

Compatible With 1983-1990 Ford Escort, front left; 1984-1990 Ford Tempo, front left; 1984-1990 Mercury Topaz, front left; and 1986-1987 Mercury Lynx, front left. This part cross-references Ford E3FZ3B436H and Mercury E43Z3B436D for the same application. Use Cardone 66-2004 when replacing a worn or noisy front left CV axle on these vehicles.

What It Helps Fix

• Clicking or snapping during turns from a worn outer CV joint
• Grease on the chassis or suspension from a ruptured outer boot
• Vibration at speed caused by axle runout or shaft distortion
• ABS warning light issues after axle replacement when the sensor ring is damaged or missing
• Thumping or driveline shake related to a failing CV axle assembly

Installation Notes and Tips

• Fits 1990, 1989, 1988, 1987, 1986, 1985, 1984, and 1983 model years listed for the supported Ford and Mercury applications.
• Do not let the CV drive axle hang unsupported during service; this can damage the inner joint.
• Do not use an impact wrench to install the retaining nut. Torque the nut to the vehicle manufacturer’s specification.
• Do not reuse a prevailing-torque lock nut; install the new nut supplied with the axle.
• Replace transaxle seals when servicing CV axle assemblies to help prevent leaks.
• If the ABS light remains on after installation, inspect the sensor ring, sensor, and nearby wiring for damage.

Quality Assurance

Cardone engineers and tests CV drive axles to meet or exceed original equipment performance targets. Shafts are checked for straightness and runout to help deliver vibration-free operation, while boot and seal design choices are made to reduce common failure causes in daily driving.
