drivetrain noise, please help!

Post by 93wagonship »

hi guys,

my 1993 BF wagon 4wd have developed an annoying drivetrain noise most audible from 60 mph (100 km/h) and up.

the noise appears to come from the transmission and is not related to RPM

in the video below it is possible to hear (like a saw working in the wood shop)

when the clutch pedal is depressed, the noise becomes worst (did it several times by the end of the video - loud noise followed by clutch pedal squeaks)

the noise began soon after a head gasket and clutch job, but the mechanic say it's unrelated and wants to charge another $700 to open the transmission and inspect the bearings

please help!

cheers

It sounds like the throw out bearing, was it replaced when the clutch was replaced?
(Edit)
I listened to it again and it sounds deeper than that, it is speed dependent like a shaft bearing, or diff bearing.

Thkx man, yep new tob (exedy clutch kit). And it doesn't seems to be the problem. Yes, it's speed related (from about 50 mph on).

Anyway to calm that noise down a little? Change the diff fluids or use mOs2 (like liquymoly)?

Depending on how much it wil set me back, I'm selling the car as is, unfortunately cannot diy.

My old 93 did the same thing when I replaced the clutch. I knew it was the tob but I sold it before I billed the tranny back out

Hope deeply it's just the tob. Maybe the guy just didn't lube the shaft properly...

Today I've managed to suck about a quarter of transmission/front diff excess oil. Now the dipstick read F again. Washed underneath to see if the leaking axles will stop leaking.

I was observing the job, the guy also inverted the heater hoses (upper / lower) which I've managed to undo. Also, he used RTV in the valve cover gasket, wtf? Well, I'm not going back there anyway.

Cheers

Well I've had a professional to diagnose this and most likely bearings inside the transmission / differential. Will not fix it now though.
