FITTING FOR THE LONG HAUL
The main reason for premature failure of transmission products is the OE fitment of thermoplastic boot kits which are inflexible. This causes them to crack and split which in turn, allows the grease to escape. Not only does this cause the bearing to run dry, but it also allows contaminants such as dirt, grit, salt and water to get in. This causes corrosion which also speeds up the wear on moving parts.
The tri-lobal thermoplastic boot also has a tendency to leak grease through the gaps. With this in mind, it comes as no surprise that the 20 best-selling Driveshafts, CV joints and boot kits in the Shaftec range, all fit applications that have thermoplastic boots fitted as standard by the OE manufacturers.
BEARING THE FORCES
The carrier bearing on two-piece driveshafts can also be problematic, especially in modern turbo diesel vehicles. This is due to the large amounts of torque being transmitted through the bearing on hard accelerations, causing it to wear.
STEERING CLEAR OF IMPURITIES
While steering racks can suffer from a typical problem of gaiters splitting and causing the bar to rust, they can also find themselves under attack from within. Metallic and rubber fragments floating in the steering fluid can damage seals and valves along with creating blockages.
This highlights the need to thoroughly flush the system through. Even if the original fault is unrelated, these particles can settle at the bottom of the reservoir and are disturbed when the fluid is topped up causing a problem in the new unit.
Shaftec offers a comprehensive steering range with a 1-year/12,000-mile warranty as well as one of the widest ranges of driveshafts and CV joints available in Europe, which carry a 2-year/24,000-mile warranty.
