2006 LJ Rubicon - First Jeep Build - Even An Idiot Can Do It

[hosejockey61]

With the pitting or damage to the races I posted above, I was going to replace the races. Think I need to swap the bearings too?

Task a look and see if there is any damage.

Thanks, they seem ok, but not sure if you can tell just looking at them. Races seem fine besides the scratching. Ill replace the races just to be extra careful.

What do you think about cutting off and relocating the rear spring mounts while im in there? Worth doing?

I am installing a savvy under armor skid along with the currie 4" lift, so worried about how much the pinion is going to have to be turned upwards.

I can your video on it, seems straightforward enough.

Might as well why your in there.

If anyone on the forum is near Tahoe or Reno and wants a free set of black painted moabs. Let me know.

@hosejockey61

Drivers shim carrier- 0.124
Passenger shim carrier- 0.140
Pinion - factory under bearing + 0.006" under race.

I added 0.006" to pinion depth. Looks too deep to me. Should I back off to 0.003" behind the inner race?

Backlash at 0.009

That's what I wanted to see. Perfect. Now we know that your sweet spot is somewhere in those 6 thou you added. Take out 3ish (whatever is easiest combo to make) and rerun. Almost there.

Thank you Sir.

Took out 0.003" pinion shim. Does this look too shallow now, or just right?

Rear dana 44 as reminder, so we want to favor the drive side of the tooth, correct?

 

[hosejockey61]

This looks pretty good from what I can see. There is build up of paint at the root. Wipe it off and run another pattern. When taking the picture, show us the face of the tooth. Your pic is looking more from top land

Well, im back on the struggle bus. I got two new races from koyo. Same part.

I get 0.011" backlash if I put the following shims in:

Drivers side - 0.124
Passenger - 0.140.

Backlash was consistent around the gear within 0.001", Maybe 0.002"

So I went to the following shims to reduce backlash:

Drivers - 0.130"
Passenger - 0.135.

Now the backlash varies from 0.006 all the way to 0.002 around the gear. What gives?

 

[Hackyman]

I checked the carrier and ring gear for run out around the outside. The carrier is almost perfect. Less than 0.001". The Revolution gear has 0.004" around the outside in runout. With an obvious "lump" on one side.

Make 100% certain the carrier is seated all the way. I don't care what your shim numbers are, do what you have to to get the backlash in spec.

I always put the bearing caps on and tighten them down snug before running a pattern. In the past I was taught that finger tight is fine but discovered that it didn't always give a consistent reading. I snug them down every time now.

HOW you take your backlash reading really does matter. The plunger needs to be as perpendicular to the drive side of the tooth as possible. Make sure it isn't touching another tooth. Make sure it is partially pushed in prior to setting the magnet to ensure full engagement.

Thanks,

Carrier is fully seated, there is a little wiggle to the anti rotation tabs on the locker, so i know they aren't wedged.shims aren't bent.

I tightened the bearing caps snug with a ratchet.

The tightness seems to be confined to one stop, maybe 2 on the ring gear. Went back to the shim combo that gives me too much backlash and im getting readings mostly 0.011 and 0.012, with one spot of 0.008.

Should I take the ring gear off and make sure there are no burs, or junk in there?

Yep.

 

[Hackyman]

Yep.

Would you heat the red loctite, or just take them off with an impact?

impact is fine

 

[Hackyman]

I assume I should get a new set of ring gear bolts?

Fine to reuse even if they have been torqued?

As long as you red loctite them
