Squeak only when backing up?

I've got a wheel squeak that I haven't been able to locate. It only happens when I back up, I notice it in the mornings most. I jacked the truck and spun the wheels by hand and couldn't replicate the squeak, and I've driven around a parking lot a bit at slow speeds and it doesn't squeak when going forward. Any ideas welcome, I just don't want something to be worn down to nothing if the squeak is damaging something.

 

moisture accumulated on the brake pads in the morning maybe?

 

Does this squeek sound like a piece of wire wrapped around something maybe ?

& does it go away when you get a little road speed going ?

Just in reverse huh ?

Any more info would be of help maybe.

 

Only in reverse, closest I can describe it is the sound when brake pads wear but the pads are only a few months old. It sounds like it's coming from the rear. I only notice it when I'm backing out of my driveway.

 

check your "U" joints.

 

have your driveline checked out, particularly the cv joint or (ball and seat) on the rear driveline. i had the same problem about 4 months ago. The squeak would only come when i backed up and i ended up having to replace all u joints, carrier bearing and the ball and seat. but the ball and seat was the part that was making the noise, it was just worn out. how many miles are on your truck?

 

I have about 166,000 on it now. I greased the drive shaft nipples a month or so ago. So you had to replace the entire driveshaft joints? How much did that cost?

 

labor and parts was about $500, the only thing that was actually bad was the "cv joint" on the rear driveshaft, but i had everything replaced just for peace of mind considering at the time my truck had around 178k. Try something, drive down the road you live on just in first gear, get it up to about 2,000 rpms and let of the throttle, when i did this in mine i would get the ugly squeaky noise

 

Thats kinda where I was going with the "wire wrapped around something" noise, I would check U joints, get underneath your securely parked truck & with both hands grasp firmly the end of the drive shaft where the U joint sits in the yoke coming off rear diff. Now check for "wiggle" in the joint, if good you should have virtually no movement , back & forth or side to side. If you do, the U joint is bad. Repeat this on all U joints , if they all check out OK then maybe carrier (center) bearing may be the culprit. All these are not a hard Do-it-yourself thing & you'll save a ton of money also..

 

I've got the same squeak only when I back out of my driveway. I'll check my joints in the morning!!

 

dont go backwards.......

 

My truck has been showing the same symptoms lately. I've got 162,000 miles on her, so we're around the same mileage. It's been going on for a while now (maybe 1,000 miles off and on), so I tried a few different things.

First thing I did was to hose down the underside of the truck with WD 40. Anything that moves got a good dusche, and it went away for a little while.

After it came back I tried the WD 40 trick again, but to no avail. So I changed out the diff oil, thinking maybe some water seaping into the yolk was the problem. I put a couple hundred miles on her before anything changed. All of a sudden it just quit.

Tomorrow I'm going to be pulling the yolk apart to replace the front oil seal, which someone suggested to me might have gone bad, thusly making the noise. I'll let you know if that works.

 

I have the same issue of squeaking on my 2006 TRD Sport. It's been doing it for about a week and assumed that it was the rear brakes, but I just got through checking and there's still plenty of pad left. As I pulled into the driveway tonight I also noticed what sounded like a popping noise as I was breaking. I took it back out on the road and noticed that it was happening as I was accelerating and decelerating, but not at cruising speed. I checked the U-joints and everything seems really tight. I put it up on jack stands and put it in gear to see if I could replicate the problem. It is definitely coming from the shaft/diff area, but there aren't any visible signs of wear. The truck only has 63000 miles and has been rock solid until this past week. Any ideas other than U joints? The soft suspension mounts and movement when accelerating and stopping makes sense, but the connection seems tight.

 

Does it happen every time you backup, or just the first time you back up after sitting overnight? Try not pressing your brakes while backing up and see if its still there.

If brakes dont make any difference with the noise, check the things like others have suggested, but if its just brake noise, make sure your shoes are fine, and if they are, you can either get some anti-squeal for them, or just live with it.

 

I am having this same issue. A squeak squeak sound when I back up. Just got replacing a bad u joint at trsnsmission. I thought that was the culprit but squeak is still there. I checked the other u joints and they are tight. No play at all. No grease lines either. The squeak started a week ago after I left a friends house. They live on a hill so my truck was parked at an odd angle and I used the ebrake. Could it be the rear brakes?

 

Mileage is around 165000 I think.

 

put more grease in, you may not have put enough in the first time AND they may have been bone dry anyways.

open your drums and clean your hardware while it's connected. brake dust on certain parts can squeak. or just spray some silicon grease or graphite on your hardware and between the backing plate and the shoes. don't put anything on the brake lining!

 

sounds like u-joints to me, regrease them until you see grease come out of "all" the caps, not just one or two.

also chock front wheels, jack both rear wheels off ground and secure on jack stands for safety, put truck in neutral, turn back wheels backwards by hand and this will allow the u-joints to turn while you check for looseness or squeaks
