Squeaking Creaking Body / Frame Noise

[MattRoberts123]

I am having a hell of a time with some noise lately and it is starting to concern me.

If I slow down fast, or hit the brakes hard... or if I speed up quickly, the car is making an awful creaking type noise near the rear bottom, like under the back seat... (but underneath the car)

It really sounds like the body and the frame are just going to separate or something. I wonder if there is a bushing that may need to be replaced, or if something could be broken or about to brake...???

It is an 06 SUT with nothing but 17000 miles of pavement usage. Hopefully someone can offer some advice as to what the problem may be so that I can have some ammo when I take it in to the dealer

There are no greese points it's all sealed if I remember correctly. They do make noise over time (H1's are real bad) See if the service rider will go for a ride with ya maybe it's something they can locate?????

One time we had a drive shaft compression on a H2 and the tech and to do an adjustment at the rear axel. This is after a hard hit (even a curb bump)

IT may be your sway bar bushings that hold the sway bar to the frame,or other bushings in the rear suspension .I have found that useing the white lube you use on poly bushings works and lasts a good while. probably wouldnt hurt to replace the bushings any way and lube the new ones.

Emergency brake cable!

Notice how its tight over the left trailing arm! When you brake or accelerate, the cable tightens/loosens. Isolate tight spots on the cable housing where they can rub.

Tomp,

Not sure I understand, could you explain in better detail?

Thanks

cable is tight and when rear suspnesion moves the cable moves as well. This tight moving cable can cause noises with the movement
