Hardware that no longer sits flat can alter contact at the mounting point or leave the assembled fastener stack incorrect.\u003c\/p\u003e\u003cp\u003eInspect the associated bolt, nut and mounting surface at the same time. If a bracket, support, lamp mounting point or component housing is cracked or distorted, a new washer alone will not restore the attachment. Where the assembly contains a spring or sleeve, verify those separately instead of using extra washers to compensate for damaged parts.\u003c\/p\u003e\u003ch3\u003eInstallation and service notes\u003c\/h3\u003e\u003cp\u003eFollow the factory procedure for the specific assembly. Support any component that will be released, note the order of the original hardware and clean the mating contact surfaces without removing sound material.\u003c\/p\u003e\u003cp\u003eInstall the prescribed washer in its original position and use the specified fastener. Replace any companion hardware that the service procedure identifies as single-use. Apply the correct assembly torque; a washer's dimensions do not determine the fastener's tightening specification.\u003c\/p\u003e\u003cp\u003eAfter reassembly, check component alignment and retention. For lamp hardware, check the lamp's seating and required adjustment. For exhaust hardware, allow the system to cool before work, support the pipes and check clearance and the correct spring\/sleeve arrangement.\u003c\/p\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eVehicle\u003c\/th\u003e\n\u003cth\u003eModel years\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eBody and mounting application\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi A4\u003c\/td\u003e\n\u003ctd\u003e1998\u003c\/td\u003e\n\u003ctd\u003e1.8L turbo gasoline\u003c\/td\u003e\n\u003ctd\u003eB5 base sedan.
