What to Do If the Inner CV Joint Cannot Be Removed?
3 Answers
The method for removing the inner CV joint is: first remove the inner retaining ring and then knock out the inner CV joint. The inner and outer CV joints, collectively referred to as CV joints, are important components in a car's drivetrain system. Their function is to transmit the engine's power from the transmission to the two front wheels, enabling the car to drive at high speeds. The inner CV joint consists of a bell-shaped housing, a tripod bearing or steel balls, a dust cover, a retaining ring, and grease. During regular vehicle use, it is recommended that owners inspect the vehicle's chassis during each maintenance session by lifting the car with a lift. When inspecting the chassis, check whether the CV joint's boot is damaged. If the boot is found to be damaged, it should be replaced immediately to prevent wear on the inner CV joint and ensure safe driving.
Last time my car had this same issue, it took me half a day to deal with it. First step, make sure the car is lifted steadily and properly supported with stands to prevent any shaking. Then loosen all the bolts connected to the CV joint, including the axle nut. I usually use a professional puller tool to pull it out, but if it's rusted in place, it can be really tough to remove. You can start by spraying some WD-40 penetrating oil and wait 30 minutes for it to soak in, then gently tap the outer side of the CV joint with a hammer—apply moderate force to avoid damaging the bearing. If that still doesn't work, try heating it up: use a heat gun or torch to warm the CV joint housing—but don't directly heat the ball joint! The expansion from heat and contraction from cooling should loosen it. If it still won't come apart, you might have to remove the entire axle assembly and replace it with a new part. Prevention is key—regularly check for oil leaks near the brake components; less oil contamination means less rust. Above all, safety comes first—if the tools aren't right, stop immediately.
As a seasoned DIYer, removing the inner CV joint can be tricky but manageable. First, jack up the car and place wheel chocks for safety, then remove the wheel and related bolts to clear debris. I tried pulling it off with a regular wrench and a CV joint puller, but it often gets stuck. In such cases, gently tap the CV joint edge with a cloth-wrapped hammer to loosen it by vibration—avoid heavy blows to prevent bearing damage. Spraying some rust-penetrating lubricant and letting it soak helps. If it still won't budge, apply localized heat; I've used a hairdryer, but be cautious of burns and material warping. If repeated attempts fail, don’t force it—you risk damaging the driveshaft and should seek a repair shop. Experience tells me regular maintenance and greasing the CV boot prevent issues. Remember to gather all tools and work patiently.
