engine and drivetrain Wailing Noise from Trans Tunnel/Firewall

[Utah02]

Hey guys,

Anyone have an idea of what this noise is. It's a little hard to get on video sorry. It's a wailing noise coming from the transmission tunnel and firewall area. It's not a constant thing but it happens very often as of late. It does sync with my speed so if i am slowing down then the wining slows down. happens mostly when I'm at a constant speed or slowing down and doesn't sound very good. Anything helps

Thanks in advance

Center Support Bearing.  CSB.

 

Not hard to fix, makes a big mess if it seizes solid.

I had the same it was the Guibo & a lot louder, sounded like a bad TV Ghost sound effect.

 

Good luck

Recently purchased Febi CSB from following vendor. Fitment is perfect and is made in Germany for very little money.

A failing center support bearing will often signal its imminent demise by making the wailing noise when cold, the wail ceasing abruptly as the bearing warms up a bit--only to start wailing again the next time you start out in the cold.  

 

When it's wailing all the time, it's saying (in humpback whale language) "replace me before I seize and really make a mess."

I had a very similar noise and it was the center bearing.

 

I had a hell of a time getting the drive shaft castle nut off and in process ended up bending the ujoint, which subsequently led to finding a driveshaft and a 5 speed and doing the 5 sp upgrade. Significantly more time and money than just the center bearing

I'll need to look at mine to see if it will be hard. Any tips before I go at it? 

 

Thanks

To replace the CSB means you need to drop out the drive shaft. Might as well change the Guibo while you are at it if the Guibo state is poor or unknown.

 

Once you have the drive shaft out you need to seperate it in half by undoing a large nut inside the u joint. This will require a skinny 24mm spanner (Or a spanner ground down to fit) to slip inside the U joint.

 

See previous post from buckeye with photos.

MARK THE 2 HALVES OF THE DRIVE SHAFT before undoing them as they need to go back together exactly the same as the drive shaft is balanced. Just paint a mark on the 2 halves of the drive shaft in alightment and make sure the 2 marks are still in alignment when you reassemble the drive shaft.

A few years ago I did it the easy way.  I called Mesa Performance in Costa Mesa, CA.  They had a ready-to-install refurb/rebuilt driveshaft.  Easy out with the old, easy in with the refurb.  I also replaced the guibo, no reason not to.

Colby,

I just did mine tuesday evening, just remember to mark driveshaft and if your exhaust comes off easily like mine did I was done in an hour and a half, granted I did have a lift and bolts with very little corrosion.

Good luck!!

Dave, I'll have a lift luckily but I'm not so sure about bolts without corrosion. I'll hope for the best.

Thanks for the input!
