hey im new to this site i need some help somewhat narrowing this problem down, i have a 93 jeep cherokee country automatic that in 4x4 makes this metalic grinding noise that is consistant with the vehical speed, note that i just got a new transfercase a week ago all is fine with that, so what could it be? in 2wd it does not do the noise or is just to faint to hear over the magnaflow and engine sounds.any help would would be great thankyou i should mention that the front drivshaft has that constant velosity u joint thing with the two u joint

 

Did it make this noise before the "new" TC? How are you sure the TC is not to blame.

 

well i took it back to the shop they checked the tc only and said its operating fine, before the tc i never put it in 4wd because everytime i did the tc would not engage so im not sure if it did make the sound before, it sounds like its coming from the front drive shaft but upon inspection there is no shiny metal spots and the u joints seem to be fine other than they could be dry i bought the car off a guy who spoke little english so no real talk on the why he got rid of it.

 

Sounds like a bad CV/U-joint in the front drive shaft. Pull it out and see if the noise is still there...Tj

 

should i remove it then put it in 4wd since thats when the noice happens

 

Yea that way if it still makes the noise then you will know if its the TC or not...Tj

 

ok ill try to do that its snowing where i live but hopfully tomarrow i can check it out ill let you know how it goes and thanks for the replay

 

Hey NP, that's what we're here for...Tj
