O.T. ford ranger rear axle seal

Tip B-4 you drive in the new seal pack the back side with grease, this will retain the inner spring on the back side of the seal. If the spring jumps out sometimes you can git it back in and some times not, if not then you will need a new seal. I use a seal driver and that last Damm hit to hear the seal set will knock the Damm spring out, I probably am better off to just use a hammer and tap it in.

There's NO pressing needed, and IIRC, no special tools.

If that's correct, you have to drop the diffy cover, then remove the spider gear pin.

Then, push the offending axle shaft INWARD, allowing the "C-clip" to fall out of the groove in the axle.

Then, the axle can be withdrawn, and the seal popped out and replaced. The bearing is a "straight roller bearing". If it has not been making noise, and the rollers look good, and the wear surface on the axle shaft is good, you should NOT need to replace the bearing.

Get a new bolt to retain the spider gear pin, and reassemble everything, and put the correct oil in the diffy.

You probably might as well replace the other seal as well, they are less than $5.00, and once you have the spider gear pin out, it's not much more to pop the other axle, and do both.

There's 2 seals used, depending upon HD or LD rear axle.

HD rear axle, 8.8" ring gear uses National Seal #8835S.

LD rear axle, 7.5" ring gear uses National seal #8660S.
