Transfercase oil seal

Has anyone made a tool or have suggestions for removing the old oil seal on the rear output shaft on a model 18 transfercase? Both my manuals suggest using specialty factory tools & I was wondering if anyone has come up with a different solution.

 

While there is a tool specifically made to pull seals (Harbor Freight or Sears), I've found that dropping the bearing retainer and driving it out from the rear is the easiest. Also makes installing easier too. Before you remove the retainer, might check the bearing preload. If there is excessive lash, might be a good time to slip a couple of thousands out of the shim pack.

 

Since it is not reusable, I used a plain ol' seal puller. Ended up with the seal in two pieces as it came out.

 

I use a big screw driver. Pops right out.

 

some seals come out easy by screwing a wood screw in it, then pulling it out

 

Thanks all

 

Just punch a hole in the seal, screw in a wood or sheet metal screw and then grab it with the vise grips and pull it out.You may have to use a screwdriver to leverage it out but it works fine.

If you do more than a few of these then making a tool like this is probably the way to go, especially on stuff that hasn't been touched in 30 or 40 years as the seal can actually rust right in there (fresh barn finds!). With some good planning one puller will do both the diff's & the T-case. I haven't tried it yet, but I would think it would be easier to use a flange as above with the sheet metal screws but then build a small slide hammer into it instead of a "thrust" bolt.
