Hey guys! It's been a few weeks since I have been in here. I come asking a new question!

I have noticed that after driving my truck I will 'shake' the rear of the truck and it has a "squeak" (low pitched squeak, like an old trampoline that is rusted out a bit) that I can't place. It sound like it could be coming from the shock, leaf spring, or U-bolt. The interesting thing...It goes away after about 30 seconds of rocking the truck back and forth.

I'm not sure if it's related, but i have also noticed my gas mileage has been lower for a little over a month now too. Then best I have been able to average (all highway, 95% at least) is 16mpg per the overhead console. I even increased my tire pressure to 42 psi as opposed to my normal 38-40 in efforts to help this.

Any ideas or similar stories from any of you?

 

Yeah, but it was always the suspension .

 

i wouldnt trust the mpg's on the display, i just made a post a little while back, mine is over 5 mpg's off (low) compared to hand calculations

 

the squeak could be a sticky brake shoe or pad, have you noticed any type of smell?

 

Would the brake shoe make noise when he is just rocking the truck at a stand still?

How many miles on the truck? Have you replaced the shocks?

 

I had that same squeak on my dak...started to hear it when I drove over potholes on the one side. Turned out to be the stabilizer links in the rear. Cheap and easy swap out, no more squeaks.

 

The two are not related. The squeeking is from a bad shock....or shock bushing. Could also be rear sway bar bushings, spring mount bushing, or shackle bushings.

 

sorry i left you guys...i moved over the weekend. got my internet back up and running now.

yeah, soon I will have a garage again (once i get the rest of the crap outta there) and be able to look around the shock/bushings/stabilizer links. The rear shocks have about 30-40,000 miles on them, so it's probably time to change them out! I will check the stabilizer first though.

I will hand calculate next fillup! Either way though, since i have been using the overhead display for a year now, and now the MPG's have gone down, I would assume that my hand calculations will have also gone down. I guess we will see where I am at next tank of gas!
