constant velocity joints, it provides smooth, even rotation of the drive wheels without any vibration The bearing utilizes a preloaded, non-adjustable tapered roller unit design ~ A: GENERAL The inboard end of the axle shaft is connected to the transmission via a constant velocity joint (Free-ring tripod joint : FTJ) which provides flexible capabilities in the longitudinal direction while the outboard end is supported by taper roller bearings located inside the housing via a bell joint (BJ) which features a large operating angle The hub is fitted to the tapered roller bearing inside the housing The BJ's spindle is "serration-fitted" to the hub and is clinched to it with axle nuts After front axle parts have been repaired, toe-in should be adjusted The disc rotor is an external mounting type It is secured together with the disc wheel using hub bolts to facilitate maintenance of the disc rotor Disc rotor C4-347 Fig WHEELS AND AXLES B: FRONT DRIVE SHAFT [M1B1] 4-2 The FTJ features low sliding resistance that imparts engine vibration to vehicle body, especially during idling in the "D" range The constant"-D" joint on the tire side is a bell joint (BJ) which provides a maximum operating angle of 46° I The constant-velocity joint on the transmission side uses a free ring tripod joint (FTJ) design which slides a maximum angle of 23° in the axial direction FTJ g, n HE T=13 Tire side Transmission side C4-313 Fig CONSTRUCTION OF FREE-RING TRIPOD JOINT (FTJ) The FTJ is an improved version of the TJ (tripod joint) to minimize sliding resistance In the previous TJ design, the roller rotated only in the axial direction When the joint was subjected to a "bending" angle in the sliding direction, the roller slipped causing resistance In the new FTJ design, the outer surface of the roller is provided with a free ring to minimize roller slippage, greatly reducing sliding resistance Fig 3 4-2 [M 2A0] WHEELS AND AXLES M MECHANISM AND FUNCTION Rear Axle shaft

Installation of Wheel Assembly to Vehicle 10 Tire Rotation If tires are maintained at the same positions for a long period of time, uneven wear results Therefore, they should be periodically rotated This lengthens service life of tires a When rotating tires, replace unevenly worn or damaged tires with new ones b Since "T-type" tire for temporary use is prepared as a spare tire, tire rotation is as follows 1) Before installing each wheel on vehicle, apply a continuous coat of grease to entire perimeter of centering boss on wheel hub using fingers 2) Attach the wheel to the hub by aligning the wheel bolt hole with the hub bolt 3) Temporarily attach the wheel nuts and washer to the hub bolts a Use only wheel nuts (w/washers) designed for SVX models b Wheel nuts designed exclusively for SVX's aluminum wheels cannot be used on any other vehicle, and those designed for conventional vehicles cannot be used on SVX's aluminum wheels Fig 146 1-1g [wloool 4-2 T 45 4) Manually tighten the nuts making sure the wheel hub hole is aligned correctly to the guide portion of hub 5) Tighten the wheel nuts in a diagonal selection to the specified torque Use a wheel nut wrench Wheel nut tightening torque : 98 - 118 N" m (10 - 12 kg-m, 72 - 86 ft-lb) a Tighten the wheel nuts in two or three steps by gradually increasing the torque and working diagonally, until the specified torque is reached b Do not depress the wrench with a foot; Always use both hands when tightening c Make sure the bolt, nut and the nut seating surface of the wheel are free from oils 6) If a wheel is removed for replacement or for repair of a puncture, retighten the wheel nuts to the specified torque after running 1,000 km (600 miles) 45 4-2 [w11oo) WHEELS AND AXLES 11 "T-type" Tire "T-type" tire for temporary use is prepared as a spare tire a Keep the inflation pressure at 412 kPa (4 kg/cm', 60 psi) at all times b When the wear indicator appears on the tread surface, replace the tire with a new one c Do not use a tire chain with the "?-type" tire Because of the smaller tire size, a tire chain will not fit properly and will result in damage to the vehicle and the tire d When using a T-type tire : Do not drive at a speed greater than 80 km/h (50 MPH) Drive as slowly as possible and avoid running over bumps Replace it with a conventional tire as soon as possible since this "T-type" tire
