Rotational Noise/Clunk
 

Spent the morning chasing a rotational noise that is more or less a low volume clunk. Now I need some suggestions as I could not sort it. Paying a pro is the last resort.

Symptom:
Rotational "clunk" that is audible but cannot be ascribed to a given wheel/corner
Braking enhances noise
Turning wheel to right enhances noise
Less noticeable in straight line or turning wheel left
Can't feel it in steering wheel or brake pedal
Do not think it's tires

Today's Efforts:
Raised car and checked wheel bearings wiggling and turning wheels
Fronts had more play than I like and snugged them a hair
Verified tightness of CV joints. Fine
Eyeballed front rotors and saw no evident high spots/shiny spots

Tomorrow's attack including any suggestions from you guys:
Raise azz end, jackstand. Run in 2nd gear and have wife hit brakes with clutch in. I listen.
Pull rear wheels, check caliper bolts and caliper holding screws
Put eyeball of death on calipers looking for high/shiny spots

So, please fire away with suggestions. As Ross Perot said, "I'm all ears".

I can’t tell from your post, but is the noise coming from the front or rear?

can you tape the noise or video..it?

Ivan

It seems to be coming from the rear. Not sure which side

Raining now but I will try to get a video/recording tomorrow when things are dry. I will get my wife in the car to help pinpoint the origin as her hearing has fewer rock concerts than mine.

dude ,you better not play while searching for the noise AC/DC.
Ivan

Noticed an error. Rotor holding screws. Should be tight as they were loc tited when emergency shoes were done 2 years ago.

No AC/DC. More a Classic guy - Who, Cream, Tull, Doors.....

Let's try this for sound.

Arreghhh. I will try to upload again.

I give up trying to drop a video, Been trying for 45 minutes and I am frustrated and done. Between google, android and Pixel phone it's a cluster. Thinking a trip for a new i phone.

Maybe......

it does sound to me like a CV joint..not being loose but inside the cage...

Ivan;

Thanks for the input. Is there a way to verify a CV issue before I drop a lot of $$ on a new pair of half shafts from our host?
Surprised as these were replaced about 20K miles ago with new Loebro half shafts and I lubed the **** out of them.

i would take them of the car and inspect.That means you have to slide the rubber boot off-to the center of the shaft(remove the small clamp-)If you have boot with a flange.
After mark the cv joint which way it came off.Remove the circlip on the end and take the cv joint apart.It is possible that the cage is broken.I do not think you have to buy the whole shaft just one cv joint if you find which is bad.Also was it even lubricated?

Ivan

Thanks. I will have a look tomorrow.

Yes, I lubed them when I installed them after trans rebuild. Liqui Moly LM47 and they were packed.

Other than lube issues, what causes failure? I sure don't beat on the drivetrain and the boots are intact.

If you suspect rear CV - perhaps check the mounting bolts are all tight...maybe they have loosened up a little since you swapped the shafts out previously?

I looked at the paint marks on the CV and the bolts and still aligned. I will get the torque wrench on them to verify tightness before I go farther.

Thanks

ok i listen again several times..you said you checked the rear wheel bearings.. if you turn right there is more noise....now come to think of it-and your axles are fairly new- possibly to focus on your rear left wheel bearing.....all tight,right

Ivan

the reason is ,if the cv joint would be really bad it would make more like scratchy noise not dung dung noise

don`t worry about the torque..they are tight enough;-)
Ivan

Suggestions for checking rear bearing. I lifted the car and pushed and pulled the wheel looking for play. It seems to have neither axial or radial play.
