3 < REUT > REUT REUTS recautions for Suspension REUTS : When installing rubber bushings, the final tightening must be carried out under unladen conditions with tires on ground. Spilled oil might shorten the life of rubber bushings. e sure to wipe off any spilled oil. - Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions. fter servicing suspension parts, be sure to check wheel alignment. Self-lock nuts are not reusable. lways use new ones when installing. Since new self-lock nuts are pre-oiled, tighten as they are. -3

EER RT REETS four-wheel thrust alignment should be performed. - This type of alignment is recommended for any SS/T vehicle. - The four-wheel thrust process helps ensure that the vehicle is properly aligned and the steering wheel is centered. - The alignment rack itself should be capable of accepting any SS/T vehicle. - The rack should be checked to ensure that it is level. ake sure the machine is properly calibrated. - Your alignment equipment should be regularly calibrated in order to give correct information. - heck with the manufacturer of your specific equipment for their recommended Service/alibration Schedule. ET RESS RTT: Use only the alignment specifications listed in this Service anual. When displaying the alignment settings, many alignment machines use indicators : (reen/red, plus or minus, o/o o). ever use these indicators. - The alignment specifications programmed into your machine that operate these indicators may not be correct. - This may result in an ERRR. Some newer alignment machines are equipped with an optional Rolling ompensation method to compensate the sensors (alignment targets or head units). ever use this Rolling ompensation method. - Use the acking ompensation ethod. fter installing the alignment targets or head units, raise the vehicle and rotate the wheels 1/2 turn both ways. - See nstructions in the alignment machine you're using for more information on this. djustment ER :
