Flywheel: A good rule is to resurface your flywheel every time you have your clutch worked on. Many clutch manufacturers refuse to accept warranty claims if this isn’t done, but this may or may not pertain to your driving habits and needs. There are some signs you and your mechanic should look for to see if the flywheel needs a resurface job or a complete replacement. These signs can help you decide whether resurfacing or replacing the flywheel is appropriate, as worn or badly damaged flywheels can often lead to expensive clutch repairs.

Is there glazing or discoloration? If so, your flywheel needs to be resurfaced. Glazing and discoloration are signs of wear and can prevent it from meeting the clutch smoothly. A resurface job should never cost more than about $50, and will help keep the clutch from slipping or abnormal wear.

Are there signs of cracking? This would be bad because it means the part is unsafe for continued use. Cracked flywheels can actually explode while in use, making this a very dangerous situation. Additionally, cracked flywheels also mean that the shift mechanisms could wear out quickly.

Is the part “cupped” or unevenly worn? “Cupping” is caused by the interior surface of the part being worn down by constant contact with the clutch. Uneven wear indicates another problem, such as a misaligned part or one that has too much “play” between it and the contact point. Your mechanic can tell you if this is a problem that can be solved by a resurface job or if a replacement is more appropriate. A lot depends on how badly worn the part is and how uneven the wear is. Beyond certain factory tolerances, the part has to be replaced for continued safe operation.

Clutch: What’s Included in the Clutch Repair?

Several services should be included in the clutch repair. It’s important to make sure you are getting the services you will be paying for — so, review the following list prior to getting your vehicle’s clutch repaired.

  • The clutch disc, flywheel, pilot bearing, pressure plate and throw out bearing should be inspected.
  • Replace the clutch disc. The material on this part is often, the first part of the clutch that needs to be replaced.
  • If the pressure plates are worn, they should be replaced.
  • The flywheel needs to be either replaced or resurfaced. If the flywheel is not properly repaired, it could result in vibrations when the clutch is engaged.
  • The throw out bearing should be replaced, if needed.
  • The clutch repair shop should check for fluid from the transmission or the engine, and fix any leaks that can cause damage to the clutch mechanism.

Extra Clutch Repair Cost

The repair cost could be higher if your vehicle uses a hydraulic clutch system that contains master cylinders and a slave.

Torque Converter: A torque converter takes the place of a clutch if your vehicle has an automatic transmission.

A torque converter is generally a type of fluid coupling (but also being able to multiply torque) that is used to transfer rotating power from the engine or electric motor, to a driven load. The torque converter normally takes the place of a mechanical clutch in a vehicle with an automatic transmission, allowing the load to be separated from the power source. It is usually located between the engine's flexplate and the transmission.

The key characteristic of a torque converter is its ability to multiply torque when there is a substantial difference between input and output rotational speed, thus providing the equivalent of a reduction gear. Some of these devices are also equipped with a temporary locking mechanism which rigidly binds the engine to the transmission when their speeds are nearly equal, to avoid slippage and a resulting loss of efficiency.

Transmission: We are a Certified Transmission Shop. We have transmissions that have been remanufactured at the Certified Transmission plant in Omaha. We have 1,000's of transmisions in stock in San Diego. This means that we replace your transmission and tourqe converter from ones in stock and your old ones are returned to the plant for remanufacturing. The bottom line to you is a known fixed cost and the fastest turn around possible. You get back on the road in as little as one day minimizing the inconvenience and frustration a tranamission failure can cause.

We have manual and automatic transmissions for most cars and trucks. The factory has stored hard to find transmissions that will be remanufactured on request.

Transfer Case: We have remanufactured 4 wheel drive transfer cases in stock for fast replacement.

Drve Shaft: We have driveshaft replacements and we balance driveshafts that have had u-joints replaced,

U-joints: Our drive train specialists recommend your drive shaft and U-joints be inspected regularly for optimal performance of your vehicle. Trucks and SUVs commonly have drive shaft slip joints requiring lubrication. If you hear a squeaking when you accelerate from a stop or driving you should schedule an appointment at Apex as bad U-joints can actually result in your drive shaft to separate from the vehicle.

Differential: Leaks aer the most common differential issue. We replace seals and gaskets and CV joints on fron wheel drive vehicles.
