Having a partswasher is very helpful. If not you'll want about 5 cans of brake cleaner per side. Have 3 5gal buckets and many rolls of the blue throw out paper rags. You don't need to separate the axle/birf. It'll take you 6 hours for the 1st side and 3 hours for the other. Check that you can get the 4mm bolts out of your hub before you begin your project. That got me as I had to replace hubs also $100 I didn't budget. Get a few punches and razorblades, gasket remover. Cardboard and lots of it for your garage floor.
