hello I have a 2000 chevy suburban 4x4 1500.i keep hearing a noise at low speed like 5 to 10 mph it coming from the under my feet.anyone got any ideal as to what it could be?another question I went under while in park.am I spouse be able to turn the front drive shaft some?thanks jeff

 

Could be your transfer case

 

how do I go about testing the transfer case?

 

Have you tried to shift it in and out of 4 wheel drive if it is bad it might make some noise when you do this or it might not shift into 4 wheel drive at all

 

ya no problem at shifting into and outta 4x4 everything work as it should too.

 

When's the last time you did Fluid changes on your Differentials and Transfer Case ?
Are you just putting it in 4WD, or actually shifting into Lo Range ?

 

Ok, it could be just starting to go bad or it could be that were the shaft goes into the transfer case it is getting wore just enough so that at slower speeds it wobbles but when at higher speeds its just fast enough to hold the shaft in one place, Other than taking it apart I don't think I no another way to check it

If it is not the transfer case you might want to check the oil in your transmission

 

I have no clue i just bought from guy about a month ago myself.to be safe i'm gonna change all the fuild.i may let my auto guy check it.and yes i've run it threw all the gears seem to be ok to me.i also did figure 8s and stuff before i bought i didnt hear no noise.

 

Question am I supposed be able turn the front drive shaft any at all?i can turn like 1/2 inch in each way.and that in park
