D2 5HP19 gearbox leaks. Where to go?

[notorious]

Cheers.

The right seal is now changed, but I never bothered to move the shaft up and down during the process. Will simply see how long the new seal will last.

Saw people discussing the front differential problems of these gearboxes in other forums.

If the right seal leaks again I will probably go for gearbox rebuild and reseal as you suggest. Will change the rear engine crankshaft seal too with the gearbox out!
