•Other types of increased tire wear

• Incorrect tire pressure.

•ADJUST tire pressure.

•Replacement of wheels is required.

• CARRY OUT ROOM SHIFT.

• Wrong angles of installation of forward wheels.

• ADJUST front wheel alignment. See Section 204-00 for more information.

• Car overload by weight.

• MATCH the payload specification with the required payload.

• Loose or leaking strut assembly with springs.

• TIGHTEN or INSTALL new items as needed. See Section 204-01 / 204-02 for more information.

• Worn wheel bearings.

• INSTALL new wheel bearings. See Section 204-01 / 204-02 for more information.

• Suspension elements, bushings and ball joints.

• INSPECT, REPAIR or INSTALL new items as needed.

•Excessive lateral or radial runout of a wheel or tire.

•CHECK, REPAIR or INSTALL new items as needed. Use a dial indicator to accurately measure the amount of runout.

•Difficult to install the wheel

• Incorrect application or combination of items, including wheel studs and nuts.

• FOLLOW manufacturer's specifications.

•Rust or corrosion of the wheel rim

•Bad care.

•CLEAN and APPLY paint.

• Angular vibrations of the wheels ("shimmy"), affecting the beating

• Damage to the wheel.

• INSPECT wheel rims for dents. INSTALL new items as needed.

• Front wheel bearing.

• INSTALL new wheel bearings as needed. See Section 204-01 for more information.

•Increased vehicle vibration, lack of smoothness when steering is engaged

• Suspension elements.

• TIGHTEN or INSTALL new items. See Section 204-01 for more information. (Front suspension). See Section 204-02 for more information. (Rear suspension).

•Vehicle vibration caused by tires and wheels

•Tire pressure.

•ADJUST tire pressure.

•Wheel or tire imbalance.

• BALANCE the wheel assembly.

• Uneven tire tread wear.

• INSTALL a new tire (s), if necessary to eliminate vibration.

• Unbalance of brake discs.

•CHECK the brake disc vents for dirt and foreign objects. If damage and foreign objects are not found, there may be an area of increased density in the brake disc. See Section 206-00 for more information.

• Penetration of water into tires.

•REMOVE water.

• Deformation of a disk of a wheel.

• INSTALL a new wheel rim. Attempting to straighten the wheel rim can cause cracks and weaken the rim.

• Incorrect bead fit.

• CHECK the wheel without removing it from the vehicle. INSPECT the area where the wheel rim and tire meet. If the tire looks wavy in this area during rotation, it is possible that the tire bead is not seated on the wheel rim. REMOVE the tire and CLEAN the bead seat areas on the rim and on the tire. REFER to section "Cleaning and inspection" repair procedures.

• Radial runout of a wheel or tire.

•Using a dial indicator, check the radial runout of the wheel disc and tire. If the tire or rim is out of specification, CHECK the radial runout of the wheel stud circle. If items are out of specification, INSTALL new items.

• Wheel stud, wheel nut or enlarged stud holes.

• TIGHTEN or INSTALL new items as needed.

• Penetration of foreign material between the contact surfaces of the wheel and hub.

•CLEAN contact surfaces.

• End runout of a wheel or tire

•Using a dial indicator, check the wheel and tire end runout. If the tire or wheel is out of specification, CHECK wheel hub end play. If items are out of specification, INSTALL new items.

• Front wheel bearing.

• INSTALL a new element as needed. See Section 204-01 for more information.

• Appearance of cracks on the back side of the base of the rim (rim flange fit) or in the drainage area (in the drain hole)

• Excessive load or negligent operation.

• INSTALL a new wheel. CHECK loading and operating conditions. Avoid over-inflating tires. CHECK specifications for rim load capacity, payload, tire size, ply rating, and tire geometry.

• Improper use of tools.

• CHECK installation, removal and maintenance procedures.

• Damage to the thread of the wheel studs

• Transverse displacement of the wheel relative to the wheel studs during assembly.

• INSTALL new wheel studs. INSTALL the wheel according to the instructions.

• Broken wheel studs

• Loose wheel nuts.

• INSTALL a new wheel stud. TIGHTEN to specification.

• Overload.

• INSTALL new wheel studs. TIGHTEN to specification. Compare actual loading with vehicle loading specifications.

• Broken thread

• Excessive tightening torque.

• INSTALL new wheel studs and nuts. TIGHTEN to specification.

•Traces of rust in the holes for the wheel studs

• Wheel nuts.

• CHECK the entire assembly. If there are damaged elements, INSTALL new elements. TIGHTEN to specification.

• Damaged wheel nuts

• Wheel assembly.

• INSTALL new wheel nuts. TIGHTEN to specification.

• Overtightened wheel nuts.

• OBSERVE the prescribed tightening procedure.

• Jamming of wheel nuts

•Corrosion.

•WARNING: Do not apply grease to the tapered portions of the wheel stud and nut holes. If the corrosion is weak, remove the corrosion with a wire brush. If corrosion is severe, INSTALL new wheel studs and wheel nuts. If corrosion persists, LUBRICATE the first three threads of each wheel stud with a graphite-based lubricant

• Overtightening wheel nuts.

• OBSERVE the prescribed tightening procedure.
