Rear Diff Coverd In Oil Film

[DAS KAMU]

saw under the car today while putting in the alloy subframe collars

and saw oil in a few areas around the diff

what id like to know is do you just use some automotive silicone/sealent

as id like to remove the cover and reseal it

cheers

will put a pic up in 5 mins

[DAS KAMU]

heres a pic of the general area

just want to know what is the best sealent someone said "rtv" wtf is that?

it was a lil moist as its prob coming out of the breather as i had been hway drivng for an hour before hand

yes its a real bad pic sorry

[DAS KAMU]

oh hicas will go in the bin at the same time ill be doing this next week

[badhairdave]

give it a clean and confirm where it's coming from first. It's very unlikely to be the seal between the housing and the backing plate as they don't just start leaking randomly.

If anything it is either the breather or possibly one of the seals on the out put shafts. Also the front section of the housing looks pretty clean in your photos so it sort of points to the breather, and possibly an over full diff.

[DAS KAMU]

could you point out what you mean?

which are the seals on the out put shafts

[badhairdave]

at a guess 38342.

Bit hard to tell from the diagram. Basically, pop out the out put shaft and there is an oil seal pressed into the housing. It's an item that wears so it's the more likely culprit.

[DAS KAMU]

looks like there marked 38342

what kind of an effort is needed to swap these over in case i ever have to?

[DAS KAMU]

by out put shaft

your meaning the outputs either side of the diff yeah?

is that a huge job?

i can use a hoist which is good

[badhairdave]

Yep

Easy job, you just have to tap them out with a hammer as there is a circlip holding them in and then you will see the seal.

Rip that out however you can (small flat blade works well enough) and tap in a replacement.

Job done

[DAS KAMU]

noob question

would it be better to remove the diff and put it on a bench to do this yeah?

if yes how hard is that?

wil i need to buy other stuff as well ?

such as other shit perishing etc

[badhairdave]

It's easy enough doing it on the car.

I've done it both ways on different cars. Off car is easiest, however getting the diff off and on is a bit of work on it's own.

On car it's just undo the drive shaft bolts, push it out of the way, dump the oil and pop out the out put shaft

ok that sounds good

cant wait to have a go will do it next week with pics

have ordered the seals

ill do it with the diff off as the diff mounting bushes have perished so ill do it all together

what about the abs etc? anything needed to take extra care of?

im sure you need to mark the tail shaft and attach it the same way

[DAS KAMU]

just order'd a bunch of seals

may as well make a day of it

both rear diff output seals pn # 38342-n3100

front pinion seal for the rear diff pn # 38189-21g00

front of transfer case seal pn # 33216-05u00

back of transfer case seal pn # 33140-05u00

adds up to around $150 or so

oh and input seal for the front diff pn # c8189-03v00

[badhairdave]

I wouldn't touch the pinion seal on the rear diff. It's a dissasembly to get to them and then you need to get your pinion pre load right and confirm that the back lash is set correctly. If it isn't leaking, leave it.

[DAS KAMU]

its a little weepy so ill do it

and it will be done by someone who knows what there doing (not me lol)

[sh@un]

it's most likely the breather is being held open by crud and the oil is misting out. check that first

you could just mark where you took it off also and put it back on the same

if the nut goes back to the same spot itll have the same pretension

will do

pics when i check it all out

[DAS KAMU]

is the breather removable ?

is there like a valve in it?
