Started Grizzly locker install!

Grizzly Locker that is



What a work of Art!!



It is going to stink covering it up!


Snugging up the ring gear for test patterns.


This is why we are just snugging it up. We now are waiting on a bolt set.(and ordered a spare) Local Dealership wanted $6.00 per bolt, however Randy's Ring and pinion was $0.43 each. Hmmmmmm!


Ring gear snugged up for testing.


Measuring shims, Veneer Calipers are a must.(I think anyway)




First shim going on!




Test bearing ring gear side in place.


Shims Pinion side of carrier.


Clean case ready for carrier.


Carrier in place with one bearing cap installed.


Coast side pattern check first test.


Drive side pattern check first test.

......to be continued!

Hope to get my Ring gear bolts early this week. And need a pinion seal and pinion nut and we will be in business. Can't wait to try out the new Grizzly locker!

Got it done!!

Well I finished the install yesterday and have all the pics on photobucket so tonight I will finish the write up!! And so far I love the Grizzly's street manners. It is quiet. I have had a Ez-locker or Aussie in my TJ since I became it owner. I ran spider gears for about a month between the EZ and Aussie. And for the last two months I have had a mini spool. And this is like having the spider gears, except when a wheel slips. I slipped the inside (left turn) wheel a little on some loose sand and the other wheel grabbed and picked up the front of the jeep hard. It appears it will work great all around. I might need to change the front from a Aussie to a Grizzly! But first I will finish this write up!

And then long arm the rear!

But so far Grizzly locker two thumbs up!!

Well Finally I have a chance to add some more.


I didn't want to but I had to shim the pinion to. I had a slight pinion leak anyway. So case all cleaned up!


Test pinion race is also a great investment.


Test race slides right in, makes for quick shims changes.


Pinion parts stacked in place. Except Yoke and pinion nut. I didn't show it but I use a non-distortion thread nut for test fits. The on and off again of the distortion thread pinion nut will eventually mess up the threads of the pinion.


I chased the pattern around for a bit and then got down to getting backlash in order. Setting up for checking backlash.


Zero set


First Backlash reading was 0.011" I adjusted the Carrier bearing shims and got this reading, 0.009". I will try one more adjustment.


Backlash reading 0.008". Dana 44 spec is 0.006" - 0.010", so this is better right in the middle. This is great. now one more pinion check and we should be good to reassemble.


Here is the Crew Chief checking everything for final install!!


Here is all the stuff for installing pinion for final assembly. I put a light coat of RTV on splines to seal them. I will show a picture later of my tools for pinion install.


Everything ready to torque up.

More to come!!.....

So far still love the Grizzly

I am loving the grizzly locker. Very quiet I only hear it on very sharp turns. And after the spool it turns like a jeep again. I don't know when I will get to test the off-road manners of the grizzly but I look forward to it.

final chapter

Here is the last few steps of my install



Locker installed with non-test bearings installed.


Test pattern check.


Drive side pattern, which Randy's install guide say's is not as important for used gears. Which mine are.

and with all looking good I bring this install to a close!

Thanks

you know a picture is worth a lot of words!! And there are plenty of instructions and books out there with lots of words and stuff. I know the first time I did a set of gears a color picture for a few things would have helped allot. Same thing when I did my transfer case upgrade. Some of the drawings in the jeep manual left me with more questions than answers. But once I got into the case it all made sense.

I just wont to give anyone who tries it a little better visual understanding of what you will see.

So far great. I have to admit I haven't been able to wheel it yet. I have had it in Snow here twice now. It does pop every now and then, but nothing like my EZ locker or my Aussie locker did. And it does click when cornering but much quieter than the old lockers. I do get the occasional person in the parking lot telling me that my CV joints are going bad! LOL I usually don't have the heart to tell them I don't have CV joints.

And as you can see from the pictures it is a gorgeous piece of machined art, so I feel kind of cool just knowing it is in there looking pretty. Even if I can't see it!!

I had someone say that to me last week when pulling into the gas station. This guy goes "hey man your CVs are goin bad". I was like "CVs? What? No man that's my front aussie locker, Wranglers dont have CVs". He had this baffled look on his face and went inside.
