I bought a Yukon limited slip carrier for my 8.25 rear end. I’ve never done the swap before. From the information I’ve gathered, I need to take out the old carrier take the ring gear and bearings off and put them on the LSD carrier. Then set the backlash and tighten everything down. Is there anything else involved??

 

YOu need ot measure the back lash first, then match it when you reinstall

 

Measure the backlash first and get new carrier bearings and races, it's nearly impossible to get the old ones off without destroying them unless you have a $350 clam shell bearing puller. Swap the ring gear over and use lock tight on the bolts, remember they are reverse thread bolts, then set the backlash back to what it was before.

 

My understanding is ring gear bolts are one time use items, so get new ring gear bolts. and yes lock tight them! Make sure the bolts and holes are degreased so the lock tight works best. use a stone to lap any high spots off the gear and carrier mounting surfaces, pay close attention to the threaded holes on carrier to make sure no burrs are raised. a boiling water bath is used to heat the new ring gear to expand it to help it fit on the carrier.

new bearings are in order, the used bearings will become your set up bearings, the new ones are only installed once the proper gear pattern is obtained

 

You may hate the 8.25 after 10 hours of backlash pattern adjustments. I do

 

I’m still waiting for the dial indicator to measure backlash to come in the mail. I’m gonna have to take the lsd carrier and new bearings and races somewhere to get pressed on.

Could I use the old bolts with red lock tight or are new bolts an absolute must?

Boiling water sounds like a great idea for the ring gear! What exactly do you mean with the above?

 

You can re use the carrier bolts

 

I have reused ring gear bolts several times without issue, you don't need setup bearings for a Chrysler 8.25 carrier, you adjust the backlash with side adjusters, which you will need to buy or make a tool for.

Per others I guess that applies to the dana, not the rear end you got, so no set up bearings needed for you..

as for the bolts, many sources say one use only for the ring gear bolts, and also some have a very specific torque sequence with an intermediate torque value prikr to final torque value.

Many many people get away without paying attention to this detail. The Space Shuttle flew for thirty years, 135 times. After launches, fuel tank insulation foam was regularly found littering the launch site. But they kept flying. Upon return heat shield tiles showed signs of impacts. But they kept flying, the damage was never critical to safety after all the made it back every time.. Only once did the design flaw of the foam coated fuel tank cause the heatshield on the wing to be critically damaged. The wing melted off that Space Shuttle. A better than 99% success rate none the less.

Or to paraphrase Dirty Harry..... do you feel lucky, well do you?

Me, I put all new bolts in, just as the instructions called for. I have bad luck, why tempt it?

above links a nice differential build write up.

 

I have never used boiling water for the ring gear. If it fits snug, line it up with the ring gear bolts, start them all and then suck it down with the bolts a little at a time. As for me, I don't want water anywhere near the gears

 

Boiling water is a recommended method, it wont harm the gear. The exposure to water is brief, and because the gear is hot, like 212F hot, water instantly evaporates off and it is near dry as an old bone before you can carry it to the work bench from the kitchen. although being paranoid I have blasted out the blind bolt holes with compressed air as a percaution in case of water in the holes not evaporating out.
Use of hot gloves or pot holders is needed, run a wire thru the ring gear and leave it sticking above the water, use the wire as a handle to remove hot gear from water.

I am pretty much 100 percent certain that all our ring gears saw plenty of hot water as part of their production and or post manufacturing cleaning. It wont harm it. fear not!

 

Welp, I got it all in there this weekend. I took a long time on it making sure things were good to the best of my knowledge. Fingers crossed that it’s correct. Haven’t driven it yet because I’m doing some other stuff on it

 

Did you get the Duragrip, How well does it work?
