Diff Leak

[slideordie]

My 318iS open diff is leaking at the seal where the prop enters it. Is this repairable with a new seal or what are my options?

Thanks

me thinks me has the same problem tho mine is on a 320 diff, are the seals replaceable?? What work is required to fit them? i.e, does the whole diff have to be stripped????

I replied to this one not long ago. Use the search button to find it.
It's not a difficult job, but you must follow the instructions regarding removing and replacing the flange retaining nut exactly, or you will have a scrap diff.

Hmmm well i've left it with a very capable mechanic, i'll find out pretty soon how he got on.

Thanks Brianmoooore, i'll have a wee search here and see what it turns up

That may be the trouble. If he doesn't know the procedure required, and just dives in, dismantles what's neccessary, and changes the seal, as I probably would if I didn't know the procedure, then he won't be able to torque it up properly.
It's the dismantling procedure that's important.

Well he had a look at it and reckons I dont HAVE to replace the seals. Its only weeping a very small amount of oil, its not loosing oil as such. As I plan to replace it with an LSD in a few months I dont think its worth the hassle fixing thsi one.

Thanks for the info Brianmoooore, I searched around and found out what you are talking about so I will put it to him should we decide to replace the seals.
I have a feeling he might know anyway, he's been building rally cars for 25 years and converted a Mk1 Fiesta to RWD with a 180hp Burton Power engine when he was in his early twenties!
