The Yeti Project

So thinking everything was mint, I pressed in/on all of the remaining bearings.

Well, I forgot that the gear oil will add preload. As for how much, I wasn't sure. I started out with .003 off of both sides of the carrier. Thank goodness for this carrier bearing removal tool. It is worth every penny.




After a couple of in and outs with the carrier and the pressed on final bearings. We have the final setup numbers and patterns:

Pattern Setup Run #8: Final run

Inner Pinion Shims: .076"
Outer Pinion Shims: .069"
Pinion Preload @ 215 ft/lbs: 21 in/lbs rotation
NRGSB Shims: .051"
RGSB Shims: .037"
Backlash: .005"-.006"

Drive Pattern:





Coast Pattern:

Having the previous numbers makes a great starting point. You have done a great job, Sir!
I had to replace my front carrier because the dana 30 has a carrier break. I was using a spartan auto locker. what type of locker are you using?

FWIW, on my gear install post, I linked to the Rustys Gear special. And they still have it available!! Sweet. Sorry. LOL I got a little excited. I went to see if they list the bearing brand but they don't. I'm 90% sure they are Timken.

When I broke mine in, I had it in 4wd full time. ran for about 20 minutes then let it set for at least an hour. The housings got pretty hot on the 1st few trips, made me nervous. but according to Motive Gear, that is normal. the heat buildup is necessary to temper the gears and finish the hardening process. I've had mine in for 5 years, wheeled with 35's through mud and rocks. Regearing is not hard, just tedious, nerve wracking and PRECISION work.

You've done all the right steps and put in the time. You're patterns look good, your measurements are well documented and all that's left now is to break them in and enjoy!. Good Job!

It is a Detroit True Track. I've really only noticed it once while driving through a blizzard this past season. Half of the road was packed powder and the other was thawed wet pavement in the sunshine and heating up. I felt it engage fairly hard/grip. I wasn't ready for it the first time and it pulled to one side fairly firmly. I won't go as far as to say a lurch or a jerk, but a firm pull. I got used to it fairly quickly, but had to slow down to deal with it. Overall, it has been a good limited slip Differential. The rear hasn't really done much since I put her in.(thanks for selling me that BTW). It has helped many times out wheeling but have yet to have a level of slippage while regular pavement driving.

I'm still not done with the repair yet. I am having bent ears on axle shaft issues while installing new 760 U-joints. They're being a pain in the arse.

Definately looking forward to getting some more overland trips in this summer. We're looking in to the Pitkin/St Elmo area on the other side of the mountains from Gunnison and Aspen areas to the south east. I believe that JDGreens has done some time over there a few years back. There is also an old toll road/mountain pass just south of Wolf Creek Pass near pagosa springs area we've been thinking about going back to as well. This repair hopefully has a longer life than the last install. This one got about 24,000 miles on it before it failed, whatever it was that pushed it over the edge into the 'not gonna work' category.

I appreciate the help Doc!
