Post subject:  Diff Oil Leak & Drive Shaft Issues
Hey guys,
First post, not a good one either.
This mini hadnt been run for around 5 years, finaly put it back together in the last few months, got the engine running about 3 weeks ago.
Problem is there was oil leak and clutch fluid leak. Thanks to the help of the Minisport guys, i realised i forgot the copper washer between the high pressure hose and the slave cylinder.
Now all this oil that is leaking can be seen from the photos below, coming from the diff output flanges. I have run my hand down behind the tappet covers, and theres no sign of oil there, so in my eyes it has to be the output chaft seals, theres oil all around them (and i believe their sealed with a selastic, have new seals coming aswell).
The outer CV joint boots are both stuffed, so i have some new ones coming (no clicking on the joint).
I would like to replace and do all this work myself, im just worried that if i roll the car off the ramps, jack it up, wheels off, drums off, pry the shaft out between the pot joint and the diff, will i have enough room to get right under the car safely to get the diff output flanges off to put the new seals on, safely?
Anyway, and help and tips appreciated, and motivation :lol:

Hopefully once this is all sorted, will get the RWC done, get it on the road, and start meeting up with everyone :)

It`s best to pop the ball joints & tie rod end out & rest the wheel assy on a tin or stump of tree :-) (carefull not to damage or stretch the brake hose) as it lets you swing the axle with it`s inner guts of CV still on the end of it right out & away , leaving you the room to rip the pot out & replace the seal &/or gasket (whatever is needed)

Thats a good idea, but i have to take the shaft out anyway, both CV joint Rubbers are cracked and torn in places. I will have another look tommorow and see if i think i can reach the diff from the wheel arch rather than from underneath. Thanks for the quick reply :)

no man,,, you won`t be able to do it unless you have the car up in the air,,, or rather you will curse yourself for tring it that way,,, just jack it up & wack some axles stands under it,,, wheels off, ball joints & tie rod ends off, pop the wheel assy out a little way & rest on a tin or block or milk crate,,, swap boots , seals, gaskets, whatever you need to do & then shove it all back together

big hammer & big chissel & "SMACK" the pot joint out,,, you`ll need some rooom under the car to do that... unless you have special leyland pot joint removing tool part number such-n-such

Allright Allright, i will give it a go. I assume anywhere on the bottom of the subframe is allright to jack it up? Only have one jack stand i can see in the garage (surely the other one isnt far), but i might have to use an assortment of ramps, jacks and stands :P
Im sure i will work it out somehow, will have a go at it tommorow afternoon :)

Don't forget to drain the engine oil before you remove the pot joints. You will have a real oil leak if you don't :evil:

Yeah i wont forget, but thats whats killing me, since i put oil in the engine and got it started, its probably done 1km of driving and about 30 mins of idling....... But i have another 5L of oil to go in, so its not tooo bad.

Well i had a go today, everything was fine except the 2 ball joints, so im going to have to wait to guy buy or borrow the tool to get them done properly. Steering arm came of allright. Does look like with the right tool will be a lot easier than i thought. Just have to play the waiting game now :)

Good stuff. Although you can get the ball joints off without a cracking tool, they are a blessing once you have one in your mits.

Ended up borrowing a fork splitter of my mechanic, got both the shafts out today. Started taking photos on the 2nd shaft, step by step, so i can put a picture tutorial together for everyone else who wants to have a go.
After doing the first one, the second gets done much quicker :)

Time to go get some new grease and some diesel tommorow, and wait for my minisport parts :)

Hey guys, spent today cleaning up the shafts and joints, all good. Just used diesel, a brush and air compressor to do the cleaning. Took the flanges off the diff after that, to my delight there was no seal, or gasket goo between them, and i could clearly see the oil pressed between the flange and diff, so im 130% sure thats my leak. 8)
Can anyone give me help how to get the rubber seals off the flanges (in the pics) i have tried with flat head screwdriver, but they seem rock solid. There wasnt an issue with the seals, but i have new ones coming so i figured i would replace anyway.
Thanks for any help :)

I put them in a vice carefully, stick a flathead screwdriver in there, and whack the handle sideways. Works for me...
