Oil in maxi drive flange

[clintox]

Probably not the right heading. It was a hot day in Perth today and I notice I have oil coming out of my maxi drive axle flange cover the actual main, not the flange itself so I'm guessing maybe a blocked breather tube as its forced the oil out of the threads.
Cheers in advance for the help

I allways put a dab of silicon on the thread when replacing as all of mine leaked and came loose when new, it was a pain as i have alloys and the wheel has to be removed first.

Oil shouldn't get that far, it might be the hub seals, although my knowledge doesn't extend to which ones

[clintox]

Hub seal is good the oil is only on the outside of rim where as normally if hub seal is bad I find oil in inside of rim and brakes etc

if you have removed all but the hub seal so your wheel bearings and axle shaft to driveflange splines are getting oil lubed, then yes, will will definitely want oil out that far. All I do is a little teflon tape on the thread of the flange for the 52mm hex nut cap.

Yes check your breather as well :)

Is it leaking from behind the 5 bolts on the end cap? Spraying out in a radial pattern?

If so, it's pot luck. some maxidrives leak oil, some don't.

Nip up the 5 bolts, you'll get half a turn out of each.

And tighten everytime the oil reappears.

Max, if the driveflange bolts are coming loose would that not indicate another problem, especially if they are good bolts and being installed with good procedure?

If everything is good, then oil leaking at the flange to hub surface would just indicate inadequate seal. The right amount of RTV should fix that.

I use loctite 567 thread sealant for the gasket between the flange and hub as well as the thread on the cover nut.
No leaks ever.

Thanks guys yes it's the thread on the cover nut, being a plumber I should be able to spare a bit of thread tape

Redrovertdi, Did you have any issues with alloys and heavy duty flanges?

I think mine are due for replacement and have been worried the HD ones wouldn't fit well with alloys.

There are two types of flanges.. one is scolloped between the bolts to allow for LR alloys.. one is not.

Scolloped, and LR alloy friendly (apparently.. see point below):

Not Scolloped, and not LR alloy friendly.

That said, I tried to fit boost alloys from a Td5 to my '86 110 County and they wouldn't fit over the standard flanges..

Just be careful using tape.....the thread are a tight fit you want to make sure you can remove the nut ie doesn't bin

I use Gas thread sealant as it doesn't go hard

Clintox, bin the thread tape!

Clean the thread up with metho first and red RTV silicone. If the breather is clear problem solved.

Deaf and Dumbers don't bugger up threads, do we? :)

Why? I had Loctite master thread sealant on there. Even thought it doesnt go hard it was an absolute bugger to undo the driveflange nut. Since going to thread tape I can undo the nut that bit easier. No leaks, easy to clean up etc. RTV is not the answer to absolutely everything.

Why? Thread tape is not designed for oil or grease applications.
If it's working for you that's great.
RTV silicone is not Loctite, it's silicone and it's pretty easy to undo, especially if your a plumber.

Did I say it was the answer to everything? no.
Did I say it was the go for drive flanges, I would have at least 100 thou on 4 in my shead that say yep.
Only saying what worked for me.

haha, have to ask, why does being a plumber make it easier to undo than someone else?

The reason I dont like RTV in some situations is that it requires cleaning and removal everytime you remove/replace. The way I clean things thats my biggest time killer.

This may be a silly question, and apologies as I'm new to all of this, but where does one find this breather?

Really ?

Been used forever by fridgies to seal, surprise, surprise, oil and refrigerant.

Locktite 567 thread sealers use teflon in their compounding too and are designed for petrol/oils/gases ;)

Top of LH (long side) axle tube.

Well for one I being a deaf and dumber(probably like mechanics) have a spanner, shifter, wrench for all occasions some modified for specific jobs, some long handled some short, right angled etc etc, so undoing it won't be a problem I've got rtv silicone sealant on at the moment and fingers crossed so far so good. I did think it was strange that they haven't leaked before though, they have been on for a few months.
