After putting truck in 4-low by shifting to neutral, there is a loud clunking noise when shifting into drive. It does not do this when shifting to 4-High. Is this normal or is there a problem? My buddy has the same year Expedition and his does not make the noise when shifting to drive while in 4-low. My truck is a 98 F-150 4x4 with the 5.4. Appreciate any help.

 

Well all that I can say is that mine does the same thing and works just fine.

 

I'm guessing the clunking noise actually comes when you touch the brake pedal. To go into 4-low, you have to have the tranny in nuetral, flip the dial to 4-low, and depress the brake. The clunk is the sound of the transfer case engaging 4-low

 

Normal.

Inert.

The gear cogs don't always line up (slip in) when you shift -- UNTIL the engine starts to turn them -- whereupon they finish their engagement.

The go/no-go will be largely a random event (and mine seem to mostly clunk than not).

It is wise to not get too anxious -- and instead wait or start off gently until you're sure that it's engaged -- particularly in freezing temperatures.

 

I second what Y2K says. You needn't be concerned. I've got the floor shifter, and mine still makes the sound when going into 4-low.
