Tools You'll Likely Need:
* Jack and jack stands: Safely support the vehicle.
* Wheel chocks: Essential for safety.
* Lug wrench: Remove the wheel.
* Penetrating oil (like PB Blaster): Soak the axle nut and any other connections.
* Hammer: May be needed to break loose stubborn components.
* Large socket (and ratchet or breaker bar) for the axle nut: The size will depend on your vehicle.
* CV axle puller: Highly recommended; this tool makes the job much easier and safer. If you don't have one, you might be able to improvise, but it's risky.
* Pry bar (carefully!): Use only as a last resort and with extreme caution to avoid damaging the transmission.
* Torque wrench: (for reassembly)
General Procedure (assuming a manual transmission - automatic transmissions may differ slightly):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Raise the car safely using jack stands, never work under a car supported only by a jack.
2. Remove the Wheel: Remove the wheel and tire from the side you're working on.
3. Disconnect the CV Axle: This involves several steps:
* Remove the Axle Nut: Use the appropriate socket and breaker bar or ratchet to remove the large nut securing the axle to the wheel hub. Penetrating oil will help significantly.
* Separate the Axle from the Hub: Once the nut is off, the axle should separate from the hub. Sometimes it can be stubborn; gentle tapping with a hammer on the axle might help.
* Disconnect the Inner CV Joint from the Transmission: This is the tricky part. The inner joint might be held in place by a retaining clip (unlikely on this model but check) or it might just be a friction fit. This is where a CV axle puller is invaluable. It's designed to grip the axle and pull it out without damaging the transmission. If you don't have a puller, proceed with extreme caution. A very gentle pry bar might help, but there's a significant risk of damage to the transmission if forced incorrectly.
4. Remove the Axle: Once the inner joint is disconnected, the axle should slide out of the transmission.
Important Considerations for a 1991 Mercury Capri:
* Front-Wheel Drive: This car is front-wheel drive, which means the CV axles are integral to the drive system.
* Transmission Type: Knowing if it's a manual or automatic transmission is crucial. An automatic transmission will have different internal components and procedures.
* Repair Manual: A repair manual specific to your 1991 Mercury Capri is highly recommended. It will have detailed diagrams and instructions tailored to your vehicle's exact specifications.
Disclaimer: This information is for guidance only. Working on your car carries risks. If you're not comfortable performing this repair, it's best to take your car to a qualified mechanic. Incorrectly removing or reinstalling a CV axle can cause significant damage to your transmission.
