Ok, been tooling around with my truck the past couple days, just getting to all the little things I have wanted to for a while, and over the last week I have had one thing pop up that is rather annoying. When I backup, I have this horrible squeak, sounds like rubber rubbing together. I have lubed all u-joints, checked t-case fluid, etc. as this is in the area where its coming from. Anyone got any ideas what else I can check? I occasionally hearing it going forward at low speeds, but its rather faint and disappears quickly, but in reverse, its always there. Thanks in advance for the help guys.

im no mechanic but i've always heard the way to tell if you have a u joint bad put it in reverse and see if it sqeaks lol but let the others chime in

 

I know you said it sounds like it is coming from the middle of the truck but check your brakes and e-brake one could be dragging in reverse but in a why so you dont hear it moving forward
good luck figuring out a noise is always a PITA

 

Done all 4 corners in the last month. Never hurts to recheck though.

 

Another detail I did not mention... If I jack up the *** end, then put it in reverse it doesnt make the noise. So it must be something when its getting put under stress, or at least some force to move.

 

replace the u joints, they can make a bunch of different noises, one of mine went out and sounded horrible. New u joints can be bought for like 12 bucks each. so even if they are still good its a cheap place to start

 

^ i agree.

 

+1 on U joints. Mine did exact same thing. Mine didn't wiggle, but the rear was frozen in the yoke, didn't move a bit. Needle bearings were literally dust.

 

Yup go with the U-joints.

 

Im picking up new ones this morning when I get off work, will be swapping them this afternoon. Will post afterwards with an update. Thanks guys!

Got the U-Joints done today, went ahead and replaced both and glad I did. The front one wasnt too bad, but the back one.... Man! 2 of the cups were fine, but the other two looked as if they hadn't seen grease in a few years. The roller pins inside the cup had broken down and were rust powder. Im amazed I hadnt had more problems with it. Took it out and she drives like new. Amazing what new fluid in the case and some u-joints can do.

Thanks for the help, it made my life a little easier.

Mine just started making the same sound. It only happens after I have driven a while. I also can only hear it when turning at slow speeds. Could it be the same thing??

 

To try and figure out where its coming from I had my wife drive my truck slow, and I walked beside and just listened to get a feel for where it was coming from. Your noise could be a number of things (brakes, cv, t-case, u-joints). Try to get an idea what part of the truck the noise is coming from.

If it is the u-joint(s), do both at the same time. They are inexpensive, easy to change, and its worth it for the peace of mind.
Hope This Helps.

Yes it does help. I know the rear brakes will need changed soon, so it could be that. I have a new rear end the only thing that stayed the same was the brakes and u-joints. So I will just change them both. Thanks........
