Tranny & Diff. Fluid

[HKSemo]

Well tomorrow I'm getting my transmission and differential flushed(well drained) and adding new fluid.

It hasn't been done since forever, my car has about 120k miles on it, 5 speed manual trans, RWD of course.

The ultimate reason for us changing the fluid is because of a strong tranny or rear end whining while driving (notice it specifically loud when driving near a semi truck and or a wall...ear drum piercing even lol)

My question or discussion....is the whining being cause by the lack of tranny fluid or diff fluid?

both are getting replaced either way tomorrow with synthetic blend 85w-140 gear oil, and im hoping it fixes or reliefs the sound some if not completely

it's getting changed out right now.

Diff is done. Gear oil was black as ****. Same with the trans fluid.


Hopefully it stops whining :$

[HKSemo]

well its still there, just as loud


the problem is i have to get the whole rear end re-built.....**** THAT!!!


ill just say its a racing tranny whin hahahaha

is the sound coming out from the Diff ?
if yes mm you got a half life diff .
do it get louder in the turns ?

[HKSemo]

naw its the same on turns, hella loud going straight on the freeways, and pretty much by any car i drive by


its my pinion bearing, they are ****ed lol

well i am 90 % sure that its the diff. causing this sound .
because the axel gets louder on turns .
did you try to greec the diff internal before adding oil ! it should temporary resolve the problem .
when you shift gears if you dropt he clutch hard do you hear a bang from the diff ?
when you changed the oil did you notice any small metal shiny thingy drop with it ?

we sprayed carb cleaner inside the diff

nope...i dont drop the clutch hard anyways

we put a magnet stick inside, hardley any metal shavings at all...also the oil pan that we drained it into, has a magnet in/around the hole, which had very little shavings aswell

answered in your quote lol

try to greec the diff internal with large chunks and i think every thing will be fine
