Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
Hi, my name is XXXXX XXXXX the noise like a roaring noise, like alot of air moving?
hi tim. i wouldn't say it sounds like a lot of moving air, it sounds like it's stuck inbetween gears, but the display shows that it's changing gears with no problems. kind of like a loud vibration. you can feel the vibration on the floorboard.
does the noise change with the rpms of the motor?
no. its only between 40-60 mph. it stops after 60.
It sounds like a bad fan clutch, does it only do it when driving? does it do it when it in park and you rev the motor high?
only when driving.
the fan does continue when i turn the car off. it stops on its own.
then its not the fan clutch, is this all wheel drive orXXXXX can you put it in 2wd or is it always in 4wd?
always in 4wd
ok then this is all wheel drive, can you feel the vibration in the floor?
yes, can feel the vibration on the floor.
then I suspect your problem is in theViscous coupler in the transfer case, this is common, the all wheel drives have a viscous coupler in the transfer case that allows the front wheels to slip when on dry pavement, when these fail it can cause the vibration you are having, it can also be caused by bad fluid in the transfer case,I would have the transfer case drained and new fluid put in first, if this does help, then you will have to go into the transfer case,Tim
what and were is the transfer case?
and is that something i can get to easily, or will i need to take it in?
the transfer case is behind the transmission, it splits the power to the front and rear wheels, we charge about 45 dollars to service the transfer case, most quick lubes also do this,tim
also, is it common to have this problem only between particular mphs.
that's all great to know (most quick lubes do it).
thank you for the info!
anytime my friend,Tim
