Axle housing leaks

Mon Sep 02, 2013 5:19 pm

Just finished mowing and discovered gear lube dripping from the drain hole under the brake band on each axle housing. The right side seems worse than left but both dripping pretty good. New seals for the axles?

Check the level of your final drives first. Yes - Seals for sure. You will probably have to burn your brakes dry also. They get soaked when it leaks there.

Keep in mind those seals are more for keeping dust out than they are for keeping oil in. You may have excess condensation in your tranny allowing the lube to raise above the axle in which case you probably just need to drain and flush the trans and refill with 3 1/2 pints of gear lube.

They are grease seals, have you ever noticed a numbered lo boy [ transmission is the tank for the hydraulic fluid ] ? The seal is near the fluid level. If the seals , bearings and shaft are good it will not leak.But check the transmission for water in the fluid more than likely it will have some in it.You will need to replace the seals. This is just my opinion.

I am with Barnyard on this one. I would drain and refill and not worry about the seals.

There are four seals in that area.

Wouldn't hurt to replace all four.

Just getting back to this. Looks like I need seals are 385872R91 and 381907R91. Anybody have the NAPA numbers for these? Maybe 10681 for the diff seal? Thanks!

Thanks Barnyard. I knew I had seen that list before but I couldn't find it.
