There is no standard life expectancy of springs. In general, coil springs on heavier full-sized vehicles tend to last longer than those on smaller light weight applications. To determine when coil springs need to be replaced have the springs inspected and the vehicle ride height checked by a trained professional.

There is no standard life expectancy for leaf springs. In general, leaf springs on smaller lighter weight vehicles tend to last longer then leaf springs on heavier full-sized vehicles applications. To determine when coil springs need to be replaced have the springs inspected and the vehicle ride height checked by a trained professional.

Besides supporting the weight of a vehicle, the leaf springs control the ride height and keep the tires in contact with the road. Springs also affect alignment angles and are the most important components in controling the "feel" of a vehicles suspension system.

Worn or sagging springs - Weak springs lower the chassis height of a vehicle, resulting in premature tire wear and poor handling characteristics. Sagging when loaded - Vehicles used for family transportation, works trucks, or sales fleets can benefit from upgrading to Broken original springs - Although uncommon in general, certain vehicles have been known to have a very high faliure rate of broken springs.

The most common method of coil spring inspection is checking the vehicle ride height. Measure! Don't rely on eyesight alone! This method will only catch the extreme cases of spring sag or leaning. In addition to checking ride height, look for these signs, which also indicate the coil spring requires attention: Vehicle that commonly carry extra weight, resulting in unlevel condition most of the time (family transportation, work trucks, and sales fleets).

Powder coatings are very flexible, and can flex with the metal as the spring, coils and recoils to its stationary position. Also epoxy, acrylic and hybrid powders provide excellent adhesion and hard-ness for improved resistance to chipping, abrasion, corrosion, and chemicals; and it’s flexible enough to be formable without cracking.

Our clutches are deliberately as simple as possible by design. For most uses the clutch springs we recommend are the standard ones. We only use diaphragm springs where the original clutch used them; thankfully now Yamaha has reverted to coil springs for the '2004 and on R-1' clutch we only have to deal with a diaphragm spring on the first generation R-1 motors. In normal use, with coil springs, the clutch feels the same as the original.

Gas springs provide greater tonnage per diameter than coil springs; therefore one gas spring can replace several coil springs. Gas spring output force can be easily adjusted. At a given deflection, coil springs cannot be adjusted. To increase or decrease force, an alternative duty group or spring size must be substituted.

We suggest that whenever the springs are removed and replaced, you should change your u-bolts at that time. It is a relatively inexpensive insurance policy to keep your vehicle is safe.

Orthotics lose their function, that is their ability to properly control abnormal foot function, right at about one to one and one half years. This will be on the lower end if you are heavy or very active. When you reach this point (or sooner if you find your feet becoming more tired or your foot pain is returning) it is time to have them replaced.

It somewhat depends on usage, but most last 2-3 years. We usually say about 3 years for walking and cycling orthotics and about 8 pairs of shoes for running orthotics.

The Isuzu Corporate 12 bolt in the 2nd Generation Trooper (1992 - 1998) and 3rd Generation Trooper (1999 - current). The Dana 44 in the 2nd Generation Amigo (1998 - current), Axiom and 2nd Generation Rodeo (1998 - current).

Custom coils are designed to your exact specifications. They can be made either constant rate or varible rate.

There is no real evidence that silver fillings are dangerous. When they wear out, they need to be replaced. When replaced, you can choose what kind of filling you want to have.

With proper maintenance of your sediment and activated carbon pre-filters, your reverse osmosis membrane should last 2-3 years.

Not necessarily. Leaks can result from flashings that have come loose or a section of the roofing shingles being damaged by wind. A complete roof system failure, however, generally is irreversible and your roof will need to be totally replaced. Sectional damage can be the result of improper installation such as using staples to roof the home, or the nails are too short to get a good grip on the sheathing under the shingles. Also the wrong shingles could have been used for the house.

The only reason to replace implants is if there is a problem with them. For example; leakage, capsular contracture, change in shape, asymmetry, or a patient who is unhappy with size or position. Some plastic surgeons will recommend changing silicone implants even if there is not a visible problem. Speak with your plastic surgeon about implant exchanges.

It is essential that you change your UV lamp annually. The ability of the lamp to emit UV light decreases over time. Remember - UV light is invisible! Even though the lamp is still glowing after one year, there might not be enough UV light reaching your water to be effective.

Over a period of time, changes take place in the socket shape, particularly with children, creating a poorly fitting prosthesis. Therefore, the position of the eyelids may appear different to the 'good' side. There may also be reduced movement to the prosthesis. An older prosthesis may absorb secretions from the socket and cause a continual discharge and irritation.

The front struts are sealed and are maintenance free (like those on your car). If you see fluid leaking or if you feel no rebound, then you'll need to replace or rebuild them.
