GU patrol gearbox rear tailshaft seal. The seal where the back tailshaft comes out

[Bundu]

I think it is a 32 socket if I don't have it wrong. Take a shifting spanner, and size it to the nuts' flat sides, an measure gap on shifting with ruler = socket required size. You will need to remove the brake drum assembly as well before you take out that seal. Do not try to undo the H brake cable at the drum, about 30cm stream up of where it enters the drum there is a pivot mechanism from where you just unhook it easy, allow slack on the cable. Where you gonna get it in Aus, I don't know. QLD is unfamiliar territory to me. I'm from Africa which is a problem to start with that's why I refer to the agents, you prob have more options but get the right stuff. Make sure that when you replace that seal you dont damage it in any way. You will probably smile at my advice now: Buy some KY jelly from the pharmacy, lube the circumference of the seal and the seat on the box. Not too much, you want to save some of that stuff for other purposes..... like fitting pipes etc. Tap it in gently with a wood chock. Once you are done there, fill the V between the twin lips with CLEAN grease. Now carefully re-install the flange. The seal has this taper ear (tulip) shape that will face you once installed. Now lube that with some normal gearbox oil, just with your finger. Note that on the back side of the flange ( splines side) there is what looks like a washer. Make sure that is clean because that seats against that oiled tulip. Get the torque spec of that F.Nut and tighten to spec. Hope your problem is solved after that. you can grab that output shaft and wiggle it, there should be no play on it before you mount the flange. Apart from that make sure you have only that amount of oil in the TC as required. Thus fill to bottom level of filler plug. Drive your car UP and DOWN a fairly steep hill an check level again on level ground, fill again if required. If you have auto hubs, use ATF.
