OK - so my 2000, b4000 4x4 is making more noise as it goes down the road.

Its a low rumbling sound, so sqeualing or all that bad, but there is definetly more noise. Seems to come from under the drivers feet towards the centre. I put the turck in N and kept rolling the sound doesnt go away, so its not likelyl to be engine noise.

Could this be related to the u-joints or driveshaft somehow? Ive gotten 100k KMs on it thus far. When does the driveline/shaft get re-lubed (aluminum).

Wheel bearings is another option I suppose but Im really hoping thats not the case $$$.

Anything I can do to figure this out would be great.
Thx all...
P.

 

geez...so many smelling pisstakes. Sorry.

 

to check wheel bearings check for play by jacking the front up and checking for horizontal and vertical play. play both horizontally and veritcally indicates loose or bad wheel bearings.

 

Does the noise keep in line with the speed of the vehicle?

I had a bearing go out (38,000 miles, wouldn't you know it), and the sound was a constant grinding type noise, or like someone put rocks in a hubcap type of noise.

If so, I'd do the check as Seņor Conquistador suggested.

Good luck to ya.
