Transfer case fixed yoke removal?

Weeping transfer case output shaft seal on my 2019 F450.

All videos I see online show a slip type yoke on the output, mine appears to be a fixed type with a large nut.

Is it as simple as impact driving off the nut and prying out the yoke? Or are special tools and lots of cursing involved?

Anyone know the torque spec when re-assembling?

Thanks.

Well, if it is anything like the rear end in a 1999 DRW F350, it requires 450 ft/lbs of torque to install the yoke nut, and thats what this sounds like too. If it is, then you just need a big buster to get the nut off, everything else slips off. A good impact usually can remove one up to 1100 pounds tight.

Did you get that seal replaced? If so how bad was it to do? Mine is leaking and my local dealer wants $1800 to replace it.

Nope. I never was able to locate the proper seal. Used my VIN, used the model/powertrain combo, and no supplier could send me a seal that was even close to what I needed.

Couldn't even find an independent who would quote me on the job.

Luckily, I hadn't removed the old one yet.

Before breaking down and paying the dealer, I decided to see if I could "clean" the seal lip and yoke surface. I brakleened the whole area and also spread some RTV around the lip in case there were any tears I couldn't see.

Very surprisingly: it worked. I refilled the transfer case and monitored it for the next few thousand miles. No more leaking and case remained full.

It's a fairly easy job. You can get the correct seal from sewell ford.

Was going to try to tackle mine as well. 2018 F350 SRW 176”WB and this is what my setup looks like


My plan is to unbolt u-joint and set that short section leading to carrier bearing towards dog to get out of way. Unbolt large hex nut (hopefully someone knows size) and slide yoke out and pry seal out and replace mine has slinger attached to hard to see what going on until I take apart. Hopefully the seal I got from dealer is correct


Any pointers appreciated. Thank you
