So i have a problem when i have my foot on the accelerator only slightly, like when casually accelerating, there is a repeating loud squeaking. The second i take my foot off the accelerator or accelerate more the noise goes away. Can anybody shed some light on what might be going on. Thanks!

Having same problem it sound like it coming from the back right?? But it squeaks quietly when I'm rolling but I can hardly hear it then when I accelerate when I'm already moving (like 30) it squeaks loud so then I put it in neutral and I accelerate while moving and no squeak so I know it's not my belt it's only when I'm in drive and the squeak comes and goes

I think it's either my axle seal going bad because it looks like it when i look at my axle or maybe the bearings in the differential or the yoke I'm not sure

I noticed this issue on my 04 and it was due to a clip that is held down by a pin for one of the Parking/e-brake pads. The Pin holds the clip, which pins the break pad back. Items 12 & 13 here.

When i took the caliper off the clip was just sitting inside the caliper. The pin was missing. The squeaking is gone now.

i think you are right the last time i took my rotor out was to change the shoes inside and the little pins were rusty but i didn't change it because i didnt come with the shoe pads ill look into that this weekend thanks

If its in time with tire rotation its axle/wheel related. If it's significantly faster then its driveline related. Strictly based on my own experience, my prime suspect is the rear U-joint. Its usually the first to go due to it being the most exposed to water and dirt.

Yea I may spray some WD-40 on the rear u-joint ans see if that helps if not if could be that pin in the rotor

Make a big chalk mark on the tire and see how the noise relates to tire rotation. If its a u joint the noise will happen roughly 3.5 times per rotation. Another telltale sign of a u joint is a pop or a ping when going from drive to reverse or vice versa.

My rear u joint is popping does WD-40 cure this?

No but replacing it will.
