Groaning noise front rear suspension

[Funugy]

Have a groaning noise when going over bumps. Are there any lubrication point in the rear end ....grease zirts perhaps? If not, would it be advisable to spray wd40 on the suspension areas or would this do more harm than good?

pinon bearings or rear differential. You can try adding friction modifier to your diff and see if that helps

No, I don't think that's it. When the vehicle is stationary, you can bounce the fender and it makes the noise. It's definitely coming from the suspension. Any ideas on how to fix?

Shock bushings or MAAAYbe stabilizer links. Just start searching for worn or missing bushings or other rubber pieces haha

Have you looked under the truck ? What year is it? More than ten years old any of the rubber parts will start to show their age. My first guess would be swaybar end links, then ball joints. But it could be any rubber under there. Lay under the truck and have someone bounce it up and down so you can see where it's coming from.

It's an '03. Good idea on your suggestion. I'll have my wife bounce up and down as I lay underneath. Wouldn't be the first time

Also keep in mind that WD-40 will be very temporary fix if the bushing cannot be lubed. The long term fix is to have bushings replaced which is not as hard as you might think.
