Engine Modification Type

An engine modification control system may be most easily identified as one without an air pump. With engine stopped, inspect ignition wiring and vacuum hose connections. Reject Vehicle if: Wires or connections are loose, broken or leaking Any part of system is missing

Ball Joints

An inspection for ball joint wear can only be made when the joints are unloaded, except those ball joints having a wear indicator. An inspection of a ball joint which has a wear indicator must be made while the ball joint is under load with the weight of the vehicle on its wheels. To unload ball joints, the vehicle must be hoisted: Under lower control arm if spring or torsion bar is on lower control arm. The lower ball joint is the load-carrying ball joint and the upper ball joint is the nonload-carrying ball joint. Under frame if spring or torsion bar is on upper control arm. The upper ball joint is the load-carrying ball joint and the lower ball joint is the nonload-carrying ball joint. Page 27 In checking the condition of an unloaded ball joint, a ball joint gauge need not be used if the inspector is absolutely certain that the ball joint movement does not exceed the prescribed tolerances. A vehicle will not be rejected unless the vertical (up and down) or horizontal (side-toside) movement in the load-carrying ball joint has been accurately measured by a ball joint gauge and the measurement exceeds the prescribed tolerances. A vehicle requiring a special tool or method to measure ball joint movement will not be rejected unless the ball joint is obviously dangerous. Inspector/mechanics will either contact the Motor Vehicle Inspection Division at the nearest troop headquarters or visit the Missouri State Highway Patrol website to obtain manufacturer's specifications on ball joints. If the ball joint movement exceeds the prescribed tolerances, the measured movement shall be listed with the defective part on the MVI-2 form (see 11 CSR 50-2.120). Unless a dial indicator or a gauge of the type which screws into a grease fitting is used, it is recommended that the most accurate method of determining vertical (up and down) movement of the ball joint using a gauge which has a roller and pointer, is to remove the dust cup from the spindle and place the pointer rollers of the ball joint gauge on top of the spindle nut. In the event that the rollers of a particular brand gauge are too large to rest on top of the spindle nut, the rollers should then be positioned against the bottom of the spindle nut. To measure horizontal (side) movement, place rollers of gauge against tire sidewall and work wheel in and out. Inspect ball joints with wear indicator. Wipe the grease fitting and boss free from dirt and grease. Observe if boss is flush or inside the cover surface. Inspect ball joints without wear indicator by hoisting and unloading the ball joint. Position a pry bar under the front tire and wheel and with pressure sufficient only to lift the weight of the wheel assembly, move the wheel up and down and observe movement. Under no circumstances should there be more upward lifting force exerted than necessary to determine the actual movement of the ball joint stud within the housing. Grasp the tire and wheel assembly at the eleven (11) and five (5) o'clock positions. Work the wheel in and out to detect any looseness. Move hands to the one (1) and seven (7) o'clock positions and repeat. Inspect ball joints. For ball joints on Twin I-Beam axles, eliminate all wheel bearing play by applying the service brake. Raise the vehicle by hoisting under the I-Beam axle beneath the spring. Grasp the lower edge of the tire and move the wheel in and out. While the wheel is being moved, observe the lower spindle arm and the lower part of the axle jaw. Grasp the upper edge of the tire and move the wheel in and out. While the wheel is being moved, observe the upper spindle arm and the lower part of the axle jaw. Movement of .031" (thirty-one thousandths inch) or greater between the lower or upper portion of the I-Beam and ball joint indicates that a measurement should be made at the circumference of the wheel adjacent to the ball joint that exhibits movement. Reject Vehicle if: The grease fitting boss on the wear indicator type ball joint is flush or inside the cover surface MacPherson Strut Suspension System has severely worn or missing thrust bearing or mounting bushings. If piston rod is bent or unit is not securely mounted to vehicle Page 28 There is free play in any direction in a nonload-carrying ball joint, unless a manufacturer's ball joint tolerances indicate minimum allowable movement. If vertical (up and down) movement in a load-carrying ball joint exceeds prescribed tolerances Horizontal (side) movement at tire sidewalls is in excess of prescribed tolerances Twin I-Beam axle has movement greater than .031" (thirty-one thousandths inch) when measured at the outer circumference of the wheel Any joints are not secured with cotter pins or other devices, or if ball stud is loose in the mounting hole

Front and Rear Wheel Play

An inspection for front and rear wheel play, which includes steering linkage, pitman arm, idler arm, stabilizer bar(s), connections, link(s), wheel bearings, tie rod ends and adjusting sleeves, can only be made by putting the ball joints under load. To load ball joints, the vehicle must be hoisted: Under the frame if the spring or torsion bar is on the lower control Under lower control arm, close to ball joint, if spring or torsion bar is on upper control arm From the underside of axle if the vehicle is equipped with kingpins or Twin I-Beams with ball joints Inspect wheel bearings by grasping the tire, by both top and bottom, and rock it in and out. To verify that any looseness detected is in the wheel bearings, notice the movement between the brake drum or disc and the backing plate or splash shield. Inspect front wheels, king pin (spindle bolts) and idler arm for play. On vehicles with power steering, the engine must be running. Eliminate all wheel bearing movement by first applying the service brake. Grasp front and rear of tire and attempt to turn assembly right and left. Then grasp top and bottom of tire and attempt to rock it in and out. Observe movement at extreme front and rear, both at top and bottom, of tire. Inspect all steering linkage, pitman arm, stabilizer bar(s), connections, link(s), tie rods and adjusting sleeves for locked joints and looseness by working them up and down and back and forth by hand. Inspect condition of all upper and lower control arms, pivot shafts, pivot shaft mountings, radius arms, and all bushings. Reject Vehicle if: Wheel bearing looseness allows relative movement between drum and backing plate (disc and splash shield) more than one-eighth inch (1/8") measured at the outer circumference of the tire for vehicles ten thousand pounds (10,000 lbs.) Gross Vehicle Weight Rating (GVWR) or less or one-quarter inch (1/4") for vehicles more than ten thousand pounds (10,000 lbs.) GVWR. A wheel bearing falls apart when a wheel is removed to inspect a brake or if the bearing is broken Front wheel movement is in excess of one-fourth inch (1/4") for wheels sixteen inches (16") or less, three-eighths inch (3/8") for wheels over sixteen inches (16") to and including eighteen inches (18") and one-half inch (1/2") for wheels over eighteen inches (18"). (An idler arm or king pin must meet this criteria before being rejected.) Excessive vertical (up and down) or lateral (side) movement is evident in any of the steering linkage sockets, tapered studs are loose in their mounting holes, any movable joints are locked, any adjusting sleeves are loose, or any joints are not secured with cotter pins or other devices A control arm or radius arm is badly bent or broken, or if a pivot shaft or a pivot shaft mounting or any control arm, radius arm, pivot shaft bushing is badly worn or missing Stabilizer bar(s), links, connections are badly worn, missing, loose or broken.

Steering Wheel Play

An inspection for steering wheel play will consist of checking steering sector for looseness and binding condition. If vehicle is equipped with power steering, the engine must be running and the fluid level and belt tension must be adequate before testing. Turn steering wheel through a full right and left turn. If equipped, inspect energy absorbing steering column. Reject Vehicle if: Steering gear binds or jams other than at wheel stops There is more than two inches (2") of free movement in steering wheels up to and including eighteen inches (18") in diameter or more than three inches (3") in steering wheels over eighteen inches (18") in diameter Power steering belt slips, is frayed, if serpentine power steering belt has sections missing, if fluid level is below manufacturer's minimum fluid level, if hoses or connections are leaking, if a power steering unit has been disconnected and has not been converted to manual steering or if any component part is missing, loose or leaking sufficient fluid to cause droplets Energy absorbing steering column is collapsed or partially collapsed Steering wheel and steering column are not properly secured Steering gear box or steering rack assembly is not securely mounted

Inspection Procedure

Inspect motor vehicle bumpers for proper bumper height, mounting, construction and presence of bumpers. (Pickup trucks and other commercial vehicles not equipped by the manufacturer with a rear bumper as standard equipment are not required to be equipped with a rear bumper.) Vehicle design will determine how a vehicle is classified. Passenger cars and station wagons which are designed and manufactured solely as passenger vehicles will be classified as motor vehicles, except commercial motor vehicles, and must comply with the twenty-two inch (22") maximum bumper height. Motor vehicles designed as multi-purpose or utility vehicles, including Broncos, Blazers, Suburbans, Jeeps, vans, mini-vans, pickups and mini-pickups, will be considered as commercial motor vehicles. The Gross Vehicle Weight Rating (GVWR) of these vehicles will determine the maximum bumper height as specified in the statute. The following chart depicts various bumper configurations and correct locations to measure.
