My prop brake failed yesterday. Closer inspection revealed the rear oil seal has failed. It's a real mess in there! So I'm trying to remove the drive flange nut so I can get to the seal. Am I right in thinking the retaining nut is torqued up to 146->179 NM?

I'm working on my driveway and struggling to get a breaker bar in there? Any tips or advise? The transmission is in gear with the xfer box in high range to stop the thing spinning as I [try] to turn the retaining nut.

If you've not got much swinging room for the bar, you can try a bottle jack under one end of it.

You may find you will require a bar or some way to stop the flange turning. I made a flange tool to use the bolts and stop the flange, or add some big chocks in ftont of the wheels.

try turning the socket on the breaker bar a 1/4 turn to see if you can get it to align better.

Cheers

Thanks. After some tinkering I managed to get the drive flange out. What do you guys think to the state of seal landing area in the photo below? I'm guessing the grey line shouldn't be there, but it's not noticeably indented when I run my finger over the race.

I'd fit a new flange - but that's just me.

ffit the seal nearer the outer edge of the housing seal will run on a clean part of the flange then
