Superior Axle Install Question

We started installing the model 20 rear One Piece Axle Kit tonight.

Problem is getting the gap tolerance from the Timken bearing to axle correct.

We believe everything is correctly in place on both sides we still have .12 protrusion. Which Superior says should be between .02 and .06"

Therefore having to get the Spacer Machined .08 to hit the optimum figure.

Anyone else run into these Problems?

Is there a way to call Superior and ask them?

Yes. They tell me to Either Shim the Axle or grind the spacer shorter. But, worried that I have the inner seal properly seated because 98% of there customers never have this as an issue.

Thing is. At first install I was not going to change the inner seal, becaue they were in grear condition. But, after instll I had too large of protrusion. Thinking maybe the supplied inner seal was thinner I decided to install theres from the kkit. So, I had the same number with the seal I instalkled and the original seal. Makingme think I have the install correctly.

I too did this install on a buddies CJ-7 and found both sides stuck out way too far. I used a block of wood and a hammer to make sure the seals wear seated all the way.....in the end, I spent about 30 min on each spacer using a grinder to machine down the spacers. All went in well from there and it's been several years with no problems....Besides, have you every had an aftermarket part fit 100%, 100% of the time!

We really had to machine the spacer a lot.

First had it machined shorter in length by .08 inches

Then we couldn't get the spacer to install all the way back to the inner shield because there is a lip insode the axle whick was too narrow for the lip on th outer spacer to get through. Thererfore we had to get that lip machined off of the spacer.

I hope everything works out okay in the long run. We have a secure fitting spacer with a protrusion around .04 inches. But, the surface area which the spacer presses to the bearing is cut about in half.

Has anyone just welded the flange to the axle on the stock splined axle before they break? just curios if would be worth it?
