Default Drive axle outer seal leak

Hi folks,

Has anyone changed out the outer seal on their drive axle?

I have a 2007 Tourmaster T40A and notice some thick 90W-ish oil leaking over the inner wheel (and brake of course) on the passenger side. It's periodic but need to replace that ASAP especially since it's leaking on the brake drum.

I heard it wasn't necessarily a complicated process to replace that seal but wanted to reach out to see if anyone has done it and how it went.

Thanks in advance!

If DIY, buy bearings too, and have them handy, as seal leakage often indication of bearing failure/ i.e. wobble? OTOH, starting to get a few years on it.

Hello I have replaced several seals over the years and they are not hard to do. Pull the hub pop the seal and reinstall the hub. Of course inspect the bearing but they may not need to be replaced...clean the spindle where the new seal will ride. And clean the drum and pads if oil has gotten on them.
Refill the lost oil or change if needed

This ^! The fluid is from the differential so topping it off after replacing the seal would be a good idea even if little has leaked out. May even want to change the differential fluid and replace the gasket for the diff cover too just to make sure it’s fresh. It’s a messy process but not difficult.

I’ve worked on 4WDs for years and replaced seals, gaskets, etc enough times it became easier to do.

There will be no diff cover or gasket to replace its not quite like a 4wd. It is just a plug located in the diff remove the plug and oil should be right at the level or put your finger in the hole and it should be no more then your first knuckle down.
Now you would be correct on smaller vehicles like my h2, or say Ford or Chevy.
But as you mentioned the seal is very simple to replace..
