Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil. ● Unladen conditions means that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions. ● After servicing suspension parts, be sure to check wheel alignment. ● Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre- oiled, tighten as they are.

RSU SEIA0245J F SHOCK ABSORBER INSPECTION Check shock absorber for oil leakage, damage and replace if necessary. G Wheel Alignment Inspection NES000DQ DESCRIPTION ● Measure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, engine cool- ant, and lubricant are full. Spare tire, jack, hand tools and mats in designated positions. H PRELIMINARY INSPECTION ● Check tires for improper air pressure and wear. I ● Check road wheels for runout. ● Check wheel bearing axial end play. ● Check ball joint axial end play of suspension arm. J ● Check shock absorber operation. ● Check each mounting point of axle and suspension for looseness and deformation. ● Check each link, arm and member for cracks, deformation, and other damage. K ● Check vehicle posture. GENERAL INFORMATION AND RECOMMENDATIONS L ● A four-wheel thrust alignment should be performed. – This type of alignment is recommended for any NISSAN/INFINITI vehicle. – The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is M centered. – The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle. – The rack should be checked to ensure that it is level. ● Make sure the machine is properly calibrated. – Your alignment equipment should be regularly calibrated in order to give correct information. – Check with the manufacturer of your specific equipment for their recommended Service/Calibration Schedule. Revision: 2006 August RSU-5 2006 G35 Coupe REAR SUSPENSION ASSEMBLY THE ALIGNMENT PROCESS IMPORTANT: Use only the alignment specifications listed in this Service Manual. ● When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or minus, Go/No Go). Do not use these indicators. – The alignment specifications programmed into your machine that operate these indicators may not be cor- rect. – This may result in an ERROR. ● Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com- pensate” the sensors (alignment targets or head units). Do not use this “Rolling Compensation” method. – Use the “Jacking Compensation Method”. After installing the alignment targets or head units, raise the vehicle and rotate the wheels 1/2 turn both ways. – See Instructions in the alignment machine you're using for more information on this. CAMBER INSPECTION ● Measure camber of both right and left

  • Rover SD1 Suspension – the Macpherson the SD1 Has
    Rover SD1 Suspension – The MacPherson The SD1 has independent front suspension. Each front wheel moves individually from the other and the following types are common. • Leading/trailing link systems • Double wishbones • Multi link systems • MacPherson Multi link systems can provide the best comfort and handling. Next best is the double wishbone if properly set up. For instance most American cars use it but the geometry often leaves room for improvement. And then there is the MacPherson, giving good comfort and reasonable handling. Why then, did Rover choose a slightly inferior system? They preferred the double wishbone approach but it would not leave room to locate the catalytic converters needed for the U.S. market, plus the cost was higher. So the simple MacPherson was chosen which consists basically of a coil spring and shock absorber built into the spring leg. The leg pivots on a ball joint on the lower control arm. This can be either an ordinary A- arm or a narrow lower control arm which locates the lower end of the strut in the transverse direction and a separate member called a radius rod locating the assembly in the longitudinal direction. However on the SD1 the anti-roll bar serves a double function as the longitudinal link taking the drive and brake forces and thereby eliminating the separate radius rod. At the top, the SD1 has a roller bearing (not shown here) to allow the spring leg to turn without the spring winding up. The strut itself is the load-bearing member in the assembly. ie: - The spring and shock absorber hold the car up.

  • Rear Suspension Radius Rod Geometry
    INFORMATION SHEET # 05 - 2011 (V1 July 2011) Rear Suspension Radius Rod Geometry Introduction: During the two previous rounds of LVV Certifier training sessions (late 2010 and early 2011), one of the points of technical discussion LVVTA had with the LVV Certifiers was ‘ladder bars’ - a term given to a particular type of radius rod, that in some circumstances can create incorrect suspension geometry and bind. This Information Sheet summarises the outcome of the good feed-back and general concensus of those discussions LVVTA had with LVV Certifiers throughout the country, together with the like-minded view of the LVVTA Technical Advisory Committee. The Information Sheet also provides an overview of how such radius rods are to be treated by the LVV Certifiers until such time as the Suspension Chapter of the Car Construction Manual has been next amended. It is important to note that this information sheet focuses only on rear suspensions, as the use of the type of radius rod systems covered within this information sheet as they apply to front axles is dealt with separately within the Suspension Chapter of the NZ Car Construction Manual. Types of radius rods in question: Radius rods should always be designed and fixed so as to maintain correct geometric operation during full suspension extension and compression. There are three types of radius rods that have been traditionally fitted to modified and scratch-built vehicles, where maintaining correct geometry is very difficult, if not impossible. These three systems are as follows: • One system is ‘split radius rods’, which is a term given, usually to 1920s through 1940s Ford-based cars and pick-ups, where the OE radius rods that originally triangulated from the diff housing into a central pivot point on the chassis, are opened out, or ‘split’ and connected to the vehicle’s chassis side-rails.
