Leaking Nearside Drive Shaft Oil Seal

[Mad Scientist 106]

See what you make of this.

 

My car has done 2000 miles now and I have had no end of problems with a leaking driveshaft oil seal, on the passenger side.

 

All was fine when it initially hit the road. The box had been rebuilt and fitted with OE seals.

 

Unfortunately, the outer CV boot on a brand new recon shaft split and I had to change the shaft under warranty.

 

After replacing the shaft, the leak started. I presumed it was the seal that had been nicked when I replaced the shaft, so off it came again for a new seal. I used a GSF seal this time as it was all I could get. All back together and it was still leaking.

 

So I replaced the seal again, with an OE one, since I blamed the pattern GSF seal.

 

STILL LEAKING.

 

Last weekend I though i'd try another shaft. I thought it might not be sealing on the shaft correctly for some reason. However, when it came out, there is a polished pair of "lines" where the seal has been. I chucked ANOTHER seal on and put it back together.

 

ITS STILL LEAKING.

 

There is nothing loose on the box, diff housing etc.

 

I'm going mad here. Anyone got any ideas???

 

It is 100% leaking from the seal, as there is no oil above the driveshaft. Its not leaking much, but its a rally car and any leak is not acceptable to me.

 

 

HELP!!!!!!!!! Its costing a bomb in crappy seals and gearbox oil!

You are leaving the seal proud from the box slightly, aren't you? If you knock it in flush then it will often leak.

Has someone in the past used a screwdriver to remove the diff and damaged the housing? Sorry missed the bit about that side being ok for 2000 miles.

Masekwm: It wasn't 2000 miles, thats the total mileage, but it was OK for the first few hundred before I changed the shaft.

 

Anthony: Yes, leaving it proud and its going in square. I even checked against my spare box and I have been fitting them the same.

prob silly question but here goes, any play in the ball joint or have you put rose jointed bottom arms on?

[Mad Scientist 106]

No play in any joints etc.

 

Latest update:

 

New shaft and oil seal: still leaking.

 

The only thing I can possibly think now is to do with the breather. The breather is nearly 10mm standard. I stuck a piece of vac hose in the hole and joined it to my catch tank. I wonder if the 3mm bore of this is causing the box to pressurise too much and push oil out of the seal?

 

Any comments?

Stands a fair chance, I'd put it back to std and try. I've never had oil come out of the breather on any 205 gearbox, so I'd leave it standard.

[shalmaneser 26]

It's definitely the seal? Because it could be the diff housing itself leaking and dripping down onto the shaft?

 

Guess that would be fairly obvious to be fair.

 

Might be worth whipping the whole lot out and having a good clean of the mating faces, you need to loosen the subframe to get the diff out which is a PITA but it an easily be done in an afternoon.

As an aside to this, my mechanic has asked me to get a (in his words) passenger side gear box seal where the driveshaft goes in. Is this the same thing and if so, can anyone advise what part I need (i.e. is it an off-the-shelf from a general parts dealer or a Peugeot only)? I went to my local autoparts dealer and he scratched his head and said he didn't have one.

just a normal passenger side driveshaft oil seal, tyr to find a make called payen as they seem to be the best.

 

on the o.p though, my friend has this same problem with a 306 1.4 on an x reg,has had 3 shafts and 4 seals but will not stop leaking, no idea as to why, i know its an ma box and not be, but it is the same side too, pass side, it just very slowly drips. i think he is removing the box at the weekend to explore. if anything crops up ill mention it here.

The seals are available in the group buy section of the site http://forum.205gtidrivers.com/index.php?showtopic=112925

Dont forget that some types of seal used on pug boxes are not meant to be fitted flush, exact fitting specs escape my at this very moment but something like 1mm on one side and 1.5mm on the other, its all in the Haynes Workshop manual though.

The GSF seals are sh!te plus no offence meant and forgive me if i'm wrong but i think J_Turnell's a little busy these days so doesn't really prioritise the seal selling.

 

 

I still hold a small stock of them, despite not being able to compete price-wise because i'm happy to pay more than pence per seal for a better quality.

Cheers folks

LOL Baz you do make me laugh, yeah unfortunately im really tied up with work these days so only have liner seals available at the moment. But as above id try putting the breather back to standard as if its a decent quality seal and its fitted properly then it shouldnt leak. Hopefully when i do get a new order in i'll be able to knock some more money off, my supplier deals in the thousands, he's a vaccum pump specialist, so only used good quality seals, hence why i can sell them for a relatively inexpensive price.

 

cheers, James

Just to confirm that James's seals do the business, done two gearboxes with them so far and it's all dry as a bone down there!!!
