My truck has been making a rotational chirp noise lately. It happens when I turn but also sometime when I'm goijg slowly and let of the gas. It will typically chirp like 3 times and be done. Any thoughts? It's a rotational noise. First though is front axle u joints. But why would it do it when I let off the gas going slow as well? I replaced the frontmost u joint on the front driveshaft and just did both rear driveshaft joints like a week ago. Thoughts? I can't feel any in the axle u joints but I've learned most of the time you can't unless its making a clunk noise. It's a 2000 Ram 1500 46re with a open differential from a 2008 Ram 1500. It's got disk brakes front and back

 

Bearings, brakes, joints. Could easily be the axle joints as you suspect. When I have bad joints, they do what you describe.

 

Huh. Didn't think of the possibility of the wheel bearings. That's a good possibility considering the truck has 208k miles.

 

Is the noise coming from the front or rear? I get that noise from the rear periodically when I make turns left or right. I'm pretty sure its my limited slip unit chattering. I need to add more limited slip additive to quiet it down.

 

Not totally sure but I think front. I have an open rear. Not really sure what could be making the noise in the back. All u joints back there are replaced. If it back there it probably would not be cheap....

 

Did you inspect them? Lift the wheel off the ground and turn it wile watching the u joint. If it's never been replaced it wont have a grease fitting. If it does might want grease them.
