Default How to tell if U-Joints are going? Faint clicking noise from drivetrain

While doing my clutch (exedy stg1 w/ new oem flywheel) this past weekend it seemed like my u-joints felt notchy. From previous experience working on other vesicles didn't seem like this was a good sign? I do not feel any vibrations when driving the car.

However I do hear a faint ticking noise sometimes, if I press the clutch pedal in it goes away. This is at low speeds

06 wrx, vf39, 40k

On mine it was more of a grinding, scraping, squealing with some jerking/nudging vibration only when taking off and disappearing when load was light. Basically sounding like a rock in the brake pads, couldn't find it till it got bad enough to start thumping the tranny/drive shaft into the tunnel area.

I believe if you go under the car and try to wiggle the driveshaft at the U-joints and you have any play your joints are probably bad. IIRC i did this on a chevy truck once...

Good luck

Doesn't seem like U joints could go bad that fast on a 06. Possible just not likely. Any other symptoms?

I just hear a faint little clicking noise at low speeds, if I push the clutch in it goes away. I am just not sure what this is related too! argh

check your trans fluid, you probably have a couple chunks of metal that used to be teeth floating around in there.

Man it sucks not being there to hear the sound!

How fast is the clicking?

Does it speed up when you rev the engine in neutral?

Does it sound like it is coming from the engine bay or under the car?

What RPM range?

Loudness on a scale of 1-10?

The more info the better.

Jon I have something similar. Mine is a 06 wrx, 150,000 miles, stock turbo, running a different map, full hks turbo back exhaust with 4 inch down pipe. Short air intake. When slowing down I sometime I hear a clicking noise and also when driving accelerating usually you do not hear it but sometimes it creeps up and it's not super loud but is noticeable. It sounds like clicking going on and if I throw it in neutral you can hear it still but usually it goes away. It comes and goes but mostly from low speed you can hear it.

Highway not to much but if I notice it I usually throw it in neutral then back into gear once and it fusses and then stops. It sounds like it's coming from under the hood. I recently replaced my right cv axel because the inner boot went bad and was making a clank noise when in first and taking your foot off the gas provoking the car to jerk backwards and you would hear a clank. After searching for the issue I thought maybe my bad cv axel was the issue. So I replaced it Saturday actually and it got rid of the 1st hard jerk back noise after releasing your foot off the gas abruptly but I still can hear from time to time the clicking noise going
On. I may need someone to ride with me to figure this out but it's very annoying. Any ideas?

The clicking sounds pretty synced like fast but not as fast as I'm driving to be exact. If I rev the engine in neutral while driving it happens it doesn't really raise the sound of it but usually right after that it fusses for a sec and then it stops. I never had to rev it to stop it though it just does once I throw it in neutral usually. On a scale of 1-10 in sounds loudness I would say fairly an 4 maybeee.

In neutral I can rev the engine slowly higher and at any rev meter point and there isn't even a trace of the sound. I can really hoarse it loudddddd as well and hold it and not one trace of the sound. It's only when driving and mostly happening when slowing down. It doesn't do it as I speed up just will randomly start when cruising so I've been riding
With no music so I can catch it. Still factory shifter and all that. Clutch was replaced about two years ago but to be honestly the guy who did it was not qualified in my
Opinion to do it. Found out later this. He was a
Friend of my wife's family who just got out of prison and needed work and was well reputable once before so I figured I would let him do it to help him get on his feet. Bad choice because he had all kinds of problems along the way due to lack of proper work environment and tools. It didn't make any sounds like this though after that was done. This started about 3 months ago and has continued randomly since but not a day goes by I don't
Hear it!

Oh yea it does sound like it's coming from under the hood somewhere though or maybe under the car in that area but it's hard to pin point being it only happens when I drive

Get under the car and shake the driveshaft around. If you feel any play it's time for new u joints....which means a new driveshaft.
