As you may remember fluid is moving from the Driveshaft Tube into the Final drive, bad news as this fluid overfills the final drive and then gunks up the brake shoes.

So today we pull the final drive apart to replace the seals and check the gear wear!

The captions tell the story.

The 1 5/16 inch socket needed for the 4 slot ring removal tool

the cleaned final drive

Heat the drive around the ring first

The 4 slotted ring holds the seal

See how the “teeth” fit into the slots

With the ring out the bearing is exposed, it will not need to be replaced

the new seal

pressing out the old seal from behind

The Bare Ring without a seal in it

Brake shoes have to come off to take the inner drive cover off

The brake shaft has to be marked and removed

Take care not to lose this washer

with the shaft removed, lever the shoes together to remove

6 nuts hold the cover on

The cover has threads in it at 2 points, putting removal bolts in, and tightening them jacks the cover away from the housing

the cover is off, it will need to be heated to seperate the ring gear

you can see the stain from the level of the hypoid, the pinion gear looks in great shape

The ring gear is in great shape, too

Place the cover on wood blocks, heat it, and the ring gear drops out!

Inside the cover, here is the seal that was causing all the problems

The spline gear looks perfect

all ready for a new seal

The splines look great!
