Diff half shaft seal gone again.

[AndyJF]

I changed the passenger side diff oil seal a few months back.
I havent been doing any overly agressive driving but its seams worse than ever. The oil has gone everywhere.
Would there be anything that could cause this. Think i heard something about a vent on these that can get blocked.

The car is a 1.8 MK1 with tonsion lsd.
Anyone able to shead some light on this?

Are the shafts ok? They can get rusted up which would shred the Seal.

Or any sort of mark on the shaft can cause the same

You'll forgive me if I'm talking rubbish here - my wife has only owned her MX5 for 9 months and I'm not that familiar with them - yet (if it was a Mk1 Escort I'd know more about it) but many cars have bushes or bearings just inside of the seal that the shaft runs on and if these are on the way out they can let the shaft move about more than it should and this movement can cause oil leaks.

All the best, Neil.

The shafts are perfect. The part that goes into the diff look brand new.
If there is a bearing or bush gone is it cost effective to fix or should i be on the lookout for a new diff?

[sidewaysreilly]

The Seals will take up lots of play, but if bearings are gone its no big deal. They are standard taper roller bearings and easily got. I'm more concerned as to who fit the seals. They are easily damaged during insertion and by the c clip ripping a piece out of them.

[AndyJF]

Well I fitted the last one. Might get my mate whos a mechanic to do this one.
Either that or we could try organise a tech day.

[sidewaysreilly]

Do probs with that. Come up to me any saturday.Near Drogheda.

[AndyJF]

Might have to take you up on that.
Have the seal ordered now.

[AndyJF]

3 weeks to get in the diff seal of mx5 parts. Must be a fairly common part to go.

[scallan]

If you have an old seal orytake a seal out you can more than likely get a set in an agri spares shop. I can give you measurments monday if you need

[sidewaysreilly]

Balls, i can get them if needed.

Check autolinks.co.uk

I have a supplier in Dublin if your stuck. Not a stock item so had to get them special order due to the extra wiper lip on them.

[AndyJF]

Its not coming out too quickly. Only getting a small bit of oil into the diff every 3-4 days. Not even taking a full 100ml.
I have it ordered and if it gets worse ill take it off the road till I get it. Just no big long drives thats all. Lol
