Wondering what the noise level is on this model HDA3400G020WW

If the noise is in both channels then you should look for something common to both channels. Capacitors are the likely cause, but some IC's might cause it. You say that the volume control doesn't effect it, if that is the pre-amp's volume control then the fault will be after that part.

some says, it's ok. but i suggest you to change it. and keep you aware of your coolant's level and to make sure the system is proper.

Blade broken or cracked or fan motor for bearing. Check and rectify.

Most certainly,as well as, power steering,coolant,brake fluid,and check both diff levels.

check oil level

check to see if all the flappers are opening this can cause odd noise

dear sir the problem you have sounds like the solenoid that opens the drain actuater can be worn out open the bottom panel run tru a cycle observe when the solenoid open it may be that there is something causing the solenoid to buzz either worn out or a wire or something in the way causing not to close proprly thanks from gilles

check the gear case lubricant level , front propeller shaft

usually when there is a ticking noise that changes as the rpm of the engine changes it could be that not all the components in the engine are properly lubricated. you may notice that noise occur temporarily when a car has been sitting for a while and all the oil runs to the bottom of the engine. as soon as the engine is running for a couple of seconds the noise goes away because oil is splashed on all those components. i recommend you check your oil level. i used to have a stealth with an oil leak...and i always knew when the oil was low because i would start to gradually hear the ticking noise. usually and hopefully that's it. it either that or you have bend rods that are slightly tappin on something else in there. but let's be a lil optimistic.

is it level?and are you over loading it?mike
