Anyone know what it sounds like when a trans bearing is going out? I have a humming/buzzing sound coming front the trans area. The noise gets louder the faster I go. I thought it was a wheel bearing but I replaced that and still have the sound. The noise does not change while turning, it is always speed dependant.

 

Bump.

 

Check your front calipers for a seized piston.

When I first got my SS/TC it had a loud noise coming from the front end, sounded just like a bad wheel bearing should sound, with the exception is it was constant, it didn't come and go when turning left or right as you would expect with a bad wheel bearing. Turned out to be a stuck piston on my left front caliper.

 

Is your car all back together ?

 

Mine? Yeah, this was like 3 months ago.

 

That would make sense. Any idea how to check this?

It doesn't pull in any direction or even have any signs of slowing down in neutral any faster than before though...

 

No, it's getting there. Motor got here Wednesday and I dropped the car off yesterday. Should be done next week.

 

I tried lifting the front wheels off the ground and running the car to pinpoint the noise but when the wheels were off the ground the noise went away.

 

My car didn't pull to one direction or the other and I felt no drag from the seized piston. I've had seized pistons on other vehicles and it feels like your dragging a boat anchor behind you.

What tipped me off that it was a piston was when I went to replace the wheel bearing I after I had been out for a drive and noticed when I pulled the wheels off that the drives side front rotor was much hotter than the passenger side, that told me I had a brake problem. So I replaced both calipers and the noise went away, I never did end up changing the wheel bearings.

 

Alright I'll try that out. That's a pretty expensive replacement if they aren't the problem though.

 

Rebuild them. 50 a side iirc

 

That's much cheaper lol. Where at, CED?

 

Yup

 

Yep, piston's and seals in one kit and boots in another. And you might as well order new pin kits while your at it. Do it right, do it once I say.

 

I guess $200 is cheaper than $500 (if I'm lucky) but this car is a damn money pit.

 

You can service the pistons before ordering new ones, and you won't always need all new boots. Buy what you need not extra, check the pin condition if they're not covered in corrosion don't replace them. Also get some good synthetic brake parts lube and lube the crap out of it.

 

How do you service them? I lubed the pins pretty good when I replaced the brakes and they went in and out fine so I'm not too worried about them.

 

Remove piston with some air pressure (low pressure) replace with new piston and seal. Make sure the area where the piston goes is clean and use some brake fluid as lube.

 

There's a few video's a Youtube showing how to rebuild Brembo calipers.

 

Alright I'll check it out, thanks guys.

 

Sounds good! Ill be nice to see it driving around again!

 

It'll be nice just driving it again haha.

 

Any updates?

 

I just got the car back with a new LDK and immediately cracked my radiator, so now it will be awaiting an aluminum 2 core replacement.

 

Hey man, did you ever get the buzzing fixed? I have sort of the same noise when driving 50+ mph. Goes away when I let off the gas, and picks right back up when I get back on. Pretty faint noise.
