squeak in reverse!

I now have an odd high pitched squeak, only when Im backing up slowly.
Any ideas on what to check?

I would check the universal joints.

Your rear u-joint needs greasing.

Thanks for clarifying what I just said.

You are very welcome. :)

Can you be a bit more descriptive about the noise, and the conditions leading up to the noise? Does it do this whether your foot is on the brake or not? Does it get louder as you come to a stop? I think I'd be checking the rear brakes. Since I'm not sure what year and model we're talking about, I suspect something in the self adjusting mechanism inside the rear drums.

I have never heard a U-joint squeak, maybe they can do this, but at low speeds? All I have ever heard out of a bad U-Joint is a Klunk in reverse or an airplane noise at high speeds in forward. It never hurts to grease your U-Joints, but I think you've got other issues.

When they are really dry they will squeak.

O.K. that's a new one on me. Thanks BLT.

No worries, I wouldn't have believed it myself until mine did it.

Once they squeak you might as well replace them. Seeing they probably are damaged.

I've seen them so dry that the cup on the end is full of rusty powder and no needle bearings. I would think the squeak would be an early sign that means you're in for a break down.

They can squeak when going into reverse and when accelerating.

The originator of this thread said it was a High pitched squeak, When yours went out, what did it sound like? Was the squeak intermittent and get louder and louder, or was it constant? Again, this is a new one on me, maybe it will help others too.

The U joints were just replaced about a year ago.

I really need to do a full lube job- I (supposedly) had one done at Midas when I got an oil change and tire rotation, but I kind of doubt if they got all the grease fittings or not.

How long should I expect it to take me to do the full grease job? Bearing in mind this will be my first time.

About an hour or so.

DO NOT TRUST LUBE SHOPS< THEY ONLY GO FOR THE EASY FITTINGS.

These are the ones you have to hit.

For the balljoints, take the weight off of the wheels to get grease in them, jack the weigh off one side and grease them, then do the other side.

All the others can be done normally.

If you have a 4x4, remove the undrcarraige plates to get to the idler and pitman arm one.

For the u-joint you will have to get a grease gun adapter to get into the fitting seeing the space is too tight to get it with a standard grease gun end.

Put enough grease into it until grease pops out of the four round end caps. The attachment kinda goes into the zerk off xenter to put the grease in. You will see when you do it.

Don't be shy with grease at all.

Grease everything until they are plump (ball joints and tierod ends) or grease starts to come out of the part.

Some of the u-joints don't have grease fittings and you should replace it with one that does.

True, I HIGHLY recommend Moog parts, excellent quality and lifetime warranty.

The fact that the U-joints were replaced 1 year ago leads me to think there are other problems if they were replaced correctly. I hope you replaced them with the type that has the grease zerks on them. If so, Grease them and see if that cures the Squeak. But I'm still thinking Brakes.

Never assume because a part has been changed that something hasn't happened or it wasn't defective.

Nothing isn't ever a sure thing.

That's the sad truth for sure. So if the grease don't cure the problem, are you thinking a new set of U-Joints?

I am definitely leaning towards that.

Especially the rear.

Could have been a cheap u-joint installed and they don't last too long.

Correct.
Whatever autozone sold me.......this was actually the first repair I ever had to have done to my truck.....
I remember thinking at the time, "hey, this is a pretty well built truck, just needs this minor repair."


Little did I know what was to come..........:uhoh:

It has a grease fitting right?

Did you grease it after you installed it?

My father in law put them on.
Ill ask if he greased them.

Mine has just started squealing when i go in reverse. I jacked up the drivers side front and turnedthe wheel manually. It squeaked, I ttok the tire off and cecked my brakes and they were fine. I have been getting a soft clicking sound at low speeds whicj leads me to believe it is that one of the joints in the CV axle are shot and it needs replacing. If any1 agrees whith my prognosis I would ike to know it may be this dudes problem too.
