Difficulty Level

Tools/Supplies Needed:

• phillips screw driver
• standard/flat screwdriver
• q-tips
• rubbing alcohol/isopropyl
• small cup
• lithium grease
• ground strap
• can of air
• soap and water
• tooth brush

Procedure:

• one of the more common issues is a sticking or damaged cd cartridge
• you can wash the cartridge with soap and water, along with using a toothbrush
• the cartridge does not require any lubrication
• allow it to dry and reinstall
• if you find the cartridge is damaged, a new or used one can be used to replace it
• other times there will be dust lodged inside the unit, this can be repaired using a can of air or a can of dust away
• do not use an air compressor, as the pressure is too high and can damage internal components
• if there are reader issues, you can insert a self cleaning cd that runs a small brush which is embedded in the disk across the laser
• if you want to disassemble the unit, then you will need to remove it from the vehicle
• removal processes vary between vehicles
• once removed, work in an area where you don't risk the chance of losing any small parts
• wear a ground strap to ensure you don't risk damaging any internal electrical components from static electricity
• first start by removing any screws which is holding the case together
• remove the case
• inspect for any broken parts
• replace broken parts if needed
• pour some rubbing alcohol/isopropyl into a small cup
• using a q-tip, dip it in the rubbing alcohol/isopropyl and clean any areas with existing grease
• ensure that there isn't too much rubbing alcohol/isopropyl on the q-tip as we don't want it dripping on the electrical components
• once satisfied with the cleaning, allow it to dry
• using a can of air or can of dust away, blow the unit down so there isn't any dust or debris inside
• using only lithium grease and a q-tip, apply it to the areas you removed the grease from
• ensure that you do apply enough where it lubricate the area efficiently but not too much where it will cause issues
• you can test the unit before reassembly to ensure everything does work correctly
• if you want, you can also remove the rubber shock dampers, they simply pull straight off and to reinstall them you will need to push and rotate them onto the shafts
• reassembly in reverse
