Fuel Economy Obviously there is a reduction in the load on the engine if the front section of the transfer case, the front tailshaft, differential, axles and wheels are not being 'driven'. This reduction in load translates to increased fuel economy.
Maintenance Front axle seals, CV joints and the outer drive flanges wear heavily with constant use, resulting in expensive and needless repairs several times over during the life of the vehicle. The cost of overhauling the front differential housing once will be nearly twice the cost of fitting the Part Time Kit alone.
Other major parts such as the front tailshaft, axle seal surfaces on the front axles and the front differential itself also wear but at a lesser rate than the other parts. These parts will require repair - at a much greater cost - but fortunately less often.
Backlash The existing driveline has multiple points of contact where 'backlash' or 'play' can occur. There are 3 differentials in the system with many splined couplings and flanges. The accumulation of all these points of backlash often result in the sloppy feel and clunky noises when rapidly changing throttle position or when changing gears.
Fitting of the Part Time Kit reduces the total amount of backlash by 75% in some cases. The vehicle has a much tighter feel and considerably smoother gear changes. Although less noticeable in automatic vehicles, the problem still exists. The steering is also noticeably lighter.
Answer A simple kit can be fitted to the Transfer Case in approximately 5 hours. No special service tools are required. The existing centre "Diff Lock" button or lever becomes the 4WD engagement button just as in the late FJ62 & FJ73 Series Landcruiser factory engagement mechanism. A quality Free Wheel Hub set is included in the kit. There are comprehensive fitting instructions for the DIY owner. An additional benefit of this installation is the Lokka automatic diff locker can be fitted to the front differential which greatly improves traction in all 4WD situations.
