#21
UPDATE.....BTW it was 2 threads all about daddy. Dont know how one could mistaken that but this is DF can say be what ever you want.

I'm trying to keep this as budget as possible so I will be sticking with the factory trac-lock LSD. I have receipts for a whole new carrier being put in the truck a number of years ago by the previous owner, so it *should* be pretty fresh still. Can't wait to see what was inevitably f'd up by the "mechanic" during the install though...it howls pretty badly...
But so far my shopping list is as follows:
Chrysler 9.25":
-USA Standard Ring & Pinion Part # ZGC925456; 4.56 ratio (Rock Auto) - $178.17
-Motive Gear R925RMK Master Install Kit w/ Koyo Bearings (Summit) - $89.97
Dana 44:
-USA Standard Ring & Pinion Part # ZGD44456T "Thick" Gear Set; 4.56 ratio (Rock Auto) - $136.51
-Ratech 122K Minor Install Kit (Summit) - $44.97
Grand total $467 shipped (CDN). I think that's pretty damn good for a gear swap. Threw in a couple axle seals on blowout at rock auto just in case. I also have decided I'll just use the crush sleeve instead of the eliminator kit. Just doing a minor install on the front as the truck has low miles, bearings should be fine, and nobody has dicked with it yet. Also found they don't make notched cross pins for the trac-lock carrier or the D44. Only notched cross pin available is for an open diff, which has 0.010" smaller diameter than the trac-lock does. Guess i'll bite the bullet and grind the teeth. Will probably order everything tomorrow

Code:
USA standard gears are not recommended for quiet running vehicles.
Anyway, here's some pics of what I picked up
D44 on the left, 9.25 on the right
Motive master install for the rear
Minor install for the front
All looks good except the 122K Ratech kit for the front was not what I was expecting. It came with a pinion nut, pinion seal, pinion shims, carrier shims, ring gear bolts, and a diff cover gasket which I expected. Summit's site said included a crush sleeve, but it does not; instead it includes two additional packs of shims. Looking at Ratech's site, it says those two shims packs are for between the bearing and pinion head (1) and between the bearing cup and housing (2). Seems like this kit is for use with a solid spacer but I really don't know. Really confused as to where all these shims go as there are 3 different shim packs for the pinion alone. I'm confused with #1129 and #1114 found on the site below which are the pinion shims I was sent:
http://www.ratechmfg.com/dana.htm
Any idea what they're for? All I wanted was a crush sleeve, so Summit will be getting a call about misinformation. I'll try and give Ratech a call and see how what they gave me is supposed to work

Here is a picture to help as it's the same for all Dana axles...
The large diameter (inner) shim is b/t the housing and the inner pinion cup (Item 2).
The smallest shim is outer shim b/t pinion shoulder and bearing (Item 1).
I highly suggest you make setup bearings from your old bearings.
1. Setup Carrier bearings. 2 total
2. Inner Pinion CUP that goes to the housing.
I used a flapper wheel on an air tool to make them. Use on a high speed drill.
I suggest the following tools...
for measuring old/new shims --
Dial Indicator like on here
D44 FSM
Unless there is something different about a "minor" install kit...? I've only regeared 2.5x, so not an expert here.

Now I'm confused. I've had my head in the FSM for some time now and all I see in the 216 FBI (D44) section is reference to a collapsible spacer, seen here:
The 248 and 267 RBI axle sections show use of a crush sleeve as well with no reference to shims. The only axle in the FSM that appears to have pinion pre-load shims is the 286 RBI (Dana 80):
Not doubting either of your expertise but at the same time I have difficulty arguing with the manual. I am reading out of the one for my 97 if that makes a difference.
@Wh1te: I've got a tool list, some of which I have and some I don't:
Have:
-tool C-4164 for side adjusters on 9.25
-micrometer / caliper
-dial indicator
-in lb torque wrench
Don't have yet:
-case spreader for D44 (will be fabbing)
-bearing pullers
-seal drivers / race installers
I will definately be making dummy pinion bearings for the rear, but I'll have to get used to pressing on the carrier / pinion bearings for the front end as I'll be using the old ones.
