Classic Car Vibration Diagnosis Part 1 – The Three Types of Driveline Vibration

There are many different possible causes for a driveline vibration. Your wheels, tires, axles, driveshaft, transmission, clutch or torque converter and engine components are all rotating at a high rate of speed, and any one or more of these components can create a vibration if they are worn or out of spec. Worn or broken engine or transmission mounts can transmit normal vibrations that usually aren’t ever felt, and accidental body contact with the engine, transmission, or exhaust can also be misinterpreted as a driveline vibration. The first step in diagnosing a classic car vibration is to determine exactly when and under what conditions the vibration occurs.

There are three basic types of vibrations:

1. Engine RPM related – If the vibration is related to engine RPM, it will occur in all gears (and possibly even sitting still) at a particular engine RPM or above. This vibration usually can be attributed to the engine itself or anything else that turns at the same speed as the engine, such as the harmonic balancer, flywheel or flexplate, pilot bearing, pressure plate, torque converter, or transmission input shaft. It is also possible for body contact with the engine, transmission, or exhaust to cause an engine RPM related vibration. Worn or broken engine or transmission mounts can contribute to this problem. When driving the vehicle with the vibration present, maintain vehicle speed and try shifting to a lower or higher gear. If the vibration changes or goes away while maintaining the same vehicle speed, then the problem is not related to engine RPM.

2. Vehicle Speed related – If the vibration is related to vehicle speed, it will not be present until you reach a certain speed, and then it will usually start gradually and then become worse as speed increases. In some cases, it will decrease at some point, and then come back again at a higher speed. This type of vibration could be related to your wheels, tires, axles, differential, driveshaft runout, balance, or angles, universal joints, or transmission output shaft. Try the same driving test as above. If the vibration is present in third gear at 50 mph, but shifting to fourth gear at 50 MPH makes the vibration go away, then it is not going to be vehicle speed related and you can usually rule out any rotating component that is further back than the transmission output shaft. At a given MPH, your output shaft, driveshaft, axles, wheels and tires are all turning at a constant speed, no matter what gear the transmission is in.

3. Accel/Decel/Cruise related – A vibration that changes depending on whether you are accelerating, decelerating, or cruising at a steady speed could have quite a few different causes. Generally, this will be related to driveshaft angles or a worn or broken part, instead of something being out of balance. Think about what changes when the engine is under load. The engine and isolator mount loads shift; the load on the pinion bearing changes; your driveshaft angles change, possibly more than they should due to a broken engine or transmission mount; your exhaust, shifter, transmission, etc. could be contacting the body only on accel or decel; if the car has been lowered (or raised), your suspension snubbers could be contacting the body prematurely.

A vehicle works as a system, and you have to understand the relationships between all the different parts when you are trying to diagnose a driveline vibration. Determining if the vibration is related to engine speed, vehicle speed, or engine load will help you narrow down the list of possible culprits, and keep you from wasting your time looking in the wrong places.

The Factors That Make Your Car Vintage

If you are considering selling an old car that you wish to dispose of, do it only after you double-check and confirm that the car is not vintage. Old classic cars may not mean a lot to you if you are not an ardent car lover. However, selling vintage cars without knowing their worth makes you miss out on the potential gain you would have had in your bank account otherwise. Being a part of vintage car shows can remind you about the hundreds of dollars that you can gain by selling these car parts. To add to this, if you own a vintage car that works, then you can be certain of making great profit by selling it.

Before you decide on selling the car that you have owned for ages, it is vital that you understand its worth, especially if the car is worth a lot more than you think it is. Any particular vehicle that was manufactured in between the years 1920 and 1950 are considered vintage vehicles. There are a lot of individuals around the world who are into collecting classic cars and these people are called car enthusiasts. So it is vital to analyze if the car that you actually considered junk is or is not junk before you decide on selling it.

Not many people are lucky enough to own vintage cars. There are ways in which you can identify if your car is vintage or not. The most relevant and easiest way is by taking note of the year of manufacture. This information can be obtained by finding your vehicle information number which is also called as VIN and checking for details online. The Internet will give you a lot of information regarding the model and make of the vehicle. The Internet will also give you information about the manufacturing date of your vehicle which will let you identify if the car is vintage.

Though your car would be considered vintage if it was manufactured in between the years 1920 and 1950, some vintage cars are worth more than others and this depends on the number of units manufactured. This can be identified by looking up on the Internet. Another very vital consideration to be made is to find out how many units exist currently. Models that are lower in existence would be considered rare and subsequently will be worth more.

The relevance of your vehicle in history also has a direct impact on its value. Car enthusiasts and collectors consider vehicles with a history behind them to be a lot more valuable. Vehicles carrying specific memories with respect to generation are also worth more.

Finding the Top Classic Car Auto Insurance Company

If you have a collector car then it is bets to purchase insurance from a classic car insurance company. Classic cars are a specific type of cars that tend to be at least 15 years old and have a value attached to them. Classic automobiles are special cars that as long as they are kept in good condition will increase in value as they age. Typically they are already very expensive when originally purchased as new or they may be a limited number of those models manufactured.

Each state has their own regulations that must be met to be considered a classic car. The vast majority of these guidelines and regulations are similar but there are a few unique ones found among different states. Additionally collectible car clubs may have even more regulations to meet as clubs may be looking for specific types of classic cars.

Insurance is important because collectible cars can be treated as an investment that will gain value over time. The most valuable classic cars are the ones that have the original paint job, no rust and are in excellent condition with very low mileage. Typically insurance rates are determined based on the mileage on the car and its condition.

Insurance quotes can be obtained by filling out information online via a classic car insurance company site. Almost all car insurance companies will offer classic car auto insurance as well as some specialized insurers. You have many different options that can be included in your classic car insurance package that includes emergency towing, reimbursement of personal effects, car show expenses, lockout, lost keys, and roadside assistance to name but a few.

Theft is a large issue with collector vehicles and you should have a strong theft policy as having your collector car stolen can be a huge loss in assets. For well insured cars many time the insurance company will offer a reward for the recovery of the car. Many times it is less expensive for the insurance company to pay a reward for the recovery of the car rather then pay out the actual value of the stolen classic car.

Insurance rates for collectible cars can be separated out based on mileage. Many antique cars will have quite low mileage as the collectible car is usually not a persons main form of transportation but taken out for special occasions. There is a greater danger of damaging the collectible car if it is driven frequently and this will depreciate the value of the car.

It is also possible to get specific classic car auto insurance just to cover the cost of repairs and other associated costs. This is many times based on the current value of the car and the availability of parts and a skilled mechanic that can fix your collector car. As with insuring other cars your driving history will also be factored into the insurance.

After you have received a basic quote from your classic car insurance company or companies you will need to get a more detailed one that is customized for your classic car. You should be able to customize the insurance package any way you like and if you need help you should be able to receive it from the insurance company or an outside company such as the state auto insurance.
