Thread: Leaky Diff flange

This is a very handy thread, as I have the same leak, ( well i think I do).

along with the leak I have also developed a shudder and slap in the driveline ( sounds and feels like the rear end) as i release the clutch and you can hear a noise back there somewhere as I take off or if I labour it. Any Ideas????????.


this noise has and shudder has only come on since i noticed the leak..

THANKS

Scott

OK, have just ordered a new style seal and a new flange which they have in stock. Only just over $100 inc postage so I'm happy with that.

Should get it early next week.

I'll take some pics when I change it for those interested. Marking the nut position etc.

Thanks all Tony

Has the flange nut come lose Or you need more preload on pinion. Uni joint? Tail shaft had a bump and bent?

Your Uni Joint looks to be dry, it may be worn and vibrating enough to cause the seal to leak, check it out, Regards Frank.

The shudder and slap is unlikely to be directly resulted to the oil leak, unless both are due to a loose nut on the pinion shaft or, less likely, a bad U-joint at the diff. The thing that most often makes drive line slack show up as you describe is a dragging handbrake. And one of the things that causes it to drag is oil leaking from the transfer case, although obviously not the diff.

The one problem I see with changing the flange is that unless it is exactly the same thickness (length) as the old flange your bearing preload will be wrong when you line up the marks on the nut and pinion. A few thou will make a huge difference to the preload/crush tube. The method of marking the nut position is really only valid if the only part you are replacing is just the seal itself.

Hence why I don't like disturbing it. They should be the same I hope. I will mark the nut to shaft and also check preloud as I go.
If I stuff it up It's only a new crush sleeve
