I have an 03 ram with a 4.7.

I am not sure the 4wd is working properly.

Do the front wheels engage/disengage? Is there some type of automatic hub or are they engaged all the time?

Do the front wheels turn the axles and driveshaft when in 2wd?


It sounds like I am in in 4wd. I can tell the transfer case is in 2wd (When I put it into 4wd I can feel the wheels bind when turning slow).

 

No manual? If not, you can download one from Dodge.

 

put it in 4 Wheel Drive, drive slow and cut the wheel pretty sharp. You should feel it bind up a little if your front wheels are engaged...

 

Four wheel drive defintely works.

I am trying to figure out what should be turning in 2wd.

 

wheels axles and driveshaft turns in 2 wheel drive.

 

Well I guess thats not my problem.
I am leaning toward a bearing. Hopefully it is a wheel bearing and not the carrier.

I did check the wheel bearings a month ago and they seemed fine.

 

what is/do you think your truck doing that isnt right or is messed up or whatever?

 

It is making a noise. Maybe "drone" is the right word. It is most noticable if I get it up to 45 -50 and left off the gas. It may be more noticable because the RPMs are low and the engine is quiet.

Seems to fade out below 25mph. At times it is more noticable than others.

It sounds like it is coming from the front end. It seems to be more effect by vehicle sped and not engine's RPM's.

 

my front end starrted making a droning/roaring noise a while back and when i got to about that speed and let off i would slow down qicker than normal. idk if yours is doing this but it the droning noise sounds like it would be your wheel bearing/s going out.

 

Roaring / droning / humming starting about 25 MPH is exactly what my driver side wheel bearing did when it was wearing out. Eventually it starts to sound like a loud mud tire.

If it's a wheel bearing, it should be pretty easy to determine which 'side' it's coming from. It was easy to hear that my front driver side bearing was the one going bad.
