Crush Sleeve Eliminator

[Mw0297]

So I have searched and searched and found nothing. Why does no one make a crush eliminator kit for JT? Does anyone know of a shop that makes them?

I wish someone one would. That and that nitro gear and axle would make 4.30 gears for the front as well. They have them for the rear but not the front. Maybe if more people would call them and ask them too they would get on the ball and make them.

I can't imagine the demand for 4.30's is that high; it's not a step enough up from 4.10's, and 4.56's would be so similar in stepping up from 3.73's that the hole makes sense.

I've only done a couple of Ford rear ends, is the money for a crush sleeve eliminator kit really worth it?

4.30's would be perfect imo for near stock sized tires (I'm talking manual). It puts 6th just a hair shorter than what 5th is on 3.73's, which is just right in my experience for having a little hill climbing power on the highway and still getting good mpg on low load flat ground cruising.

4.30s would be perfect for the diesel with 37s or 38s. And getting rid of the crush sleeve is always a good idea

It's been 3 years anyone know anything?

Does not appear to be a thing yet.

Well I am sure there was limited development because of the double ball bearing on the outer, but now you can use a taper kit, so a elimator kit could work. Wonder if you can use a older kit if it has the correct pinion dimensions.

Might have to call Yukon to see if they can cross references something.

A question is who has a used crush sleeve that's not mangled and a lathe. I'd like to have one possibly to have a hand.

Just a FYI, these might be a option.

Just got done with the install front and back. On the back, did a taper bearing kit and crush sleeve eliminator. *
These 2 kits are not direct swap, you will need to turn down the eliminator with a lath a few thous to work with taper bearing kit.

*I used this kit since I already had the bearings.

The bearing and spacer package sold by ECS may use a modified spacer that is already turned down to work with the taper bearing, not sure, might be worth a phone call.

The taper bearing moves the bearing face in a few thous over the double roller and bottoms out before the bearing and race make contact.

My buddy used a dial indicator to measure that slop when the bearing faces are bottomed out (without shims) but still loose, then shaved that measurement off the eliminator as a starting point, then fine tuned a few more passes to allow for shims to get the right drag in/lbs when torqued.

The front eliminator install was straight forward.

Currently installing the east coast gear kit and it has been turned down already , so far work just fine

Good to know

so the spacer kit only, (https://eastcoastgearsupply.com/i-23994954-jeep-jl-rear-dana-44220mm-solid-spacer-kit.html) appears to not be modified for the tapper bearing.

and the Full kit bearing and spacer (https://eastcoastgearsupply.com/i-2...rear-conversion-outer-pinion-bearing-kit.html) has been modied.

Thanks for the feed back.

Their video about it, forgot about the shim under the front race
