Pinion seal failed , unsure of axle identity (2 Viewers)

[Themcfarland]

I recently purchased an aussie based fj45 .
It already had power steering and 4 wheel disk brakes and a 1hz in it
I am stumbling to find which axles are under it . I feel instead of the previous owner putting all of this stuff over time I wonder if he didn't just slap a 45 cab into an 80 series or even 60 series drive line
It has the f55 with granny low and 5th over drive the split tcase and full float axles but remnants of the unused parts of the wire harness and such make me think it was a gasser like a fj45 would be and the tag says f45 in the vin

I have googled till I am blind and greasy as all trying to be under the truck and comparing pics I find on here
Are there any clues to what the year changes are in the axles or something to gst me to the parts I need to look up ?

I hope to have a buddy help me pull this seal , but wonder what caused the seal to fail.. wondering if I need to order the bearings too while we're in there
I have a 16th of movement in all directions but in or out. It does make a but of noise when underway but think that's due to low diff fluid right now its slung all over the underside of the wheels ..thanks in advance .. Dave

So you think it’s potentially a 60 or 80 series frame and running gear with a 45 cab dropped on it?

Leaf springs or coils?

What does the VIN number stamped on the frame say? It’s on the front right rail in front of the passenger front tire.

What year is on the title?

Pics of the truck and axles would help identify the axles. That and we all like pics…

The title is showing 82
Ill have pics of my pinion leak but I want to get better detailed pics of the extra brackets too .
The bracket for pinion brake is still there but no disk , the rears have the drum park brake brackets .
The axles are full.floated too and the bed was not original it was an UTE setup .
Ill take better pics to show body mounts and look for frame tag tonight
its a fun puzzle , and the brief 3 week honeymoon is over she is costing me money

Looks like an axle seal leak to me not a pinion leak, most likely a clogged breather and leaking when it gets warm. Its a standard 9.5 cruiser diff, most likely not a solid pinion spacer so take that into acct when you swap the seal. Do your own research on this. Outer seal on a full float is often removed, at least that's what I do. Oil the bearings not grease. Im talking about the little seal that goes inside the spindle. Ymmv, Pull the stub shafts and replace the paper gasket and back seal on wheel bearings, insure wheel bearings are good properly tightened, lift up, see if there's up and down or side to side play. Adjust wheel bearings and adjust accordingly. Make sure mating surface for paper gasket is flat and clean, insure studs are tight and not pulled, make sure cone washers are installed. When you say "pinion brake" are you talking about bracket on back of transfer case? You might need to find a local cruiser specific shop to help you out. Your brake pads are saturated and need to be replaced also. Or clean your breather, give it a good decrease, fill diff, drive and see if the leak continues, replace rear pads after leak is fixed. Beware your brake ability is bad with saturated rear pads. Rear full float seal bearing kit should be very standard on 40/80 series. Call a cruiser vendor that knows what you have and can assist with correct parts. Might be a bent rear axle housing also. You will know when you put the rear shafts back in the diff.

Amazing info thank you for this
I have info from previous owner that the wheel ends and axle bearings are all replaced less than 2100.miles ago . Pictures were sent , but I will follow the instructions to check the back of wheel bearings and paper seals
Guess what he did at that time ? He routed the vents to a higher point within the engine bay and I suspect its kinked where its tied off with zip tie.
Thanks for the Safety warning on the brakes . I will clean them up .. Just incase I need it

Regarding the park brake / pinion brake .
It looks like there is a bracket that was positioned to hold the caliper or cable management to the caliper , that is positioned towards the back of the drive shaft over the pinion area . That is what made me think pinion brake like a 14bolt sometimes had . I have not seen or heard of anything like that on a fj on that end of the drive shaft but im new to laddcruiser and stumbling my way through it
I truly appreciate you folks taking the time to.nudge me along . I know it's likely the same questions over and over from guys and it gets old . So I appreciate the effort..
I live in Louisiana im not gonna worry about the parking brake/ebrake . The parts are hard as snot to find .
I have everything but the drum and lever portion for the rear axle brake setup but lost motivation.
I have the pull lever cable and everything mounted for the rear disk/drum setup if I get motivated . This oil seal changed my direction .
