Outer Limits 4x4 Board

just got my ute on the road and after bout 3 or 4 days driving it the car is making a weird wineing sound.
if anyone has ever heard a car with straight cut gears this is wat it sounds like. it mostly does it when i back off and dont accelerate.

it seems to be coming from the gearbox/transfer.

i really dont know what it is and its making me worry and not want to drive it!

the car is a 1977 fj45 ute with a 2f and 4 speed box. it has a brand new clutch and im pretty sure the gearbox has been reco'd.

does anyone have any ideas?

cheers

After it was Reco'd was it filled back up with oil .. stupider things have happened

idler gear in the transfer maybe??

well if it was reco'd we didnt get it done and yes we put new oil through engine, gearbox and transfer when it was finished.

i just changed oil in gearbox and transfer and the oil from the gearbox was clean as a whistle but the transfer oil is a different story. i has millions of little fillings through it(looks like glitter) and it was also pretty close to black(this was brand new oil 1 week ago).

wats the idler gear and is it worth gettin some1 to change or just get new transfer if i have to?

Sounds more like a bearing that has shit itself.

Could be one of the bearings wasn't given the correct amount of preload when it was put back together, or the thread stake wasnt enough to hold the bearing retainer at it's correct preload.

Take it to someone and have the bearings changed (as a set). May/may not need new gears, depending on the amount of abnormal wear (from incorrect position, and also the iron filings in the case), likely to be a new gear set rather than a single gear. Look at it as an opportunity for a ratio change....

not the dust shield tween the engine and gearbox hitting the fly wheel is it? Had this one before, luckily found it before we tore the Gbox out agian? Just prised it away and the noise dissapeared!

get a 2nd hand one as it sounds like idler gear as im pretty sure thats what my brother said mine was, and sounds exactly the same as mine before it blew...

reco will cost far to much for what its worth imo. but get a 2nd hand one then drive yours Till its dead

I would get another tcase as well. I changed mine when I heard a similar sound and noise stopped right away. If you havent done it before though I strongly recommend fabbing something like this up.http://www.ih8mud.com/tech/tcremove1.php
Without it its a nightmare to get the old case off the shaft. Trust me, I spent two days trying to pull it off, then I read that thread and 20mins worth of booty fab and it came straight off.

generally if you get a wine on decell it is your rear diff pinion bearings.

Once again...not with week old black oil with silver bits in it. He has already established where the noise is coming from.

your best option is take the vehicle to a desperate alcoholic with no money,
they will drink all the wine out of it!

sorry, but i had to say it!

Sounds like the hard facing has come off the gears/bearing surfaces in the t/case. The oil is black due to the heat from the gears/brg being ground away.
