In need of LP 44 master install assistance.

[Jesse J]

So as of now I am running 2 LP 44s (87 grand waggy) the rear is set up with 4.27s and a true trac. The front is basically just a bare axle housing no seals or bearings or anything. I have a true trac for the front and the G2 4.88 gears just sitting on a shelf awaiting the master install kits I ordered back in july from bjs offroad. It has become aware to me in my search that I might need a master overhaul AND a master instal for my front and just a master install for the back axle? Anyway it looks to me like amazon is the only place that might have them in stock? I just need some help :3

Rock auto or your local parts store have plenty of kits in stock.

Not sure why BJs never shipped to you but I haven’t come across any shortage for parts like these. I normally get all of my stuff from Revolution though. 

A master rebuild kit typically has even more parts than an install kit. You need the 4 bearings, shims, marking compound, ring bolts etc.

Ok sweet thank you! Does a master rebuild have all the necessary shims to set up a new gear set from scratch up front?

ordered the richmond rebuild and it didnt come with axle seals or shims. I would like to at least get the rear set up this weekend because I have 5 days off from school what is the chance the previously set up 4.27s shims will work? I am ordering a minor install kit

Why not just grab some shims from your local auto parts store? A master install kit should always come with shims. Sounds like they may have been missing.

You shouldn’t have a crush sleeve on that waggy axle. Just shims. A crush sleeve is a substitute for shims on some axles for the pinion gear. Low pinion Dana 30’s had those. Iirc the waggy axle is just shims for the pinion depth and preload.

 Take some pics along the way and let us know how it goes. 

[Jesse J]

will do! should start thursday night/friday morning hoping the rear goes smooth

[Jesse J]

got the axle shafts slide out and the carrier unbolted but I can't seem to get the carrier out. shouldnt it just slide out? I have tried the crowbar behind it trick

[watchamakalit]

Put a wrench on a ring gear bolt and rotate the pinion. Your fighting bearing preload. This is where the pros would use a case spreader.

wrench and prybar?

[watchamakalit]

No just a wrench in a ring gear bolt and let the wrench bind against the housing while rotating the pinion. The mechanical advantage of the gears gives you the avility to push the carrier out of the housing.

 

I found this guys tricks helpful.

 

 

[Jesse J]

oh I see. thanks for the help! going to go try it

[Jesse J]

didnt work at least on the top side like he said it would work

[ghetdjc320]

If the carrier fell out then it wouldn’t have had any preload as mentioned above. It should have a few thousandths of preload to keep tolerances tight and within spec. You should be able to remove it though without a case spreader (though it’s tough to get much preload without one). Keep some preload on the carrier using a prybar (careful not to damage the cover mating surface) while rotating the carrier using the ring bolt as described above. It’s going to take some elbow grease. When you cracked open the diff, was it full of oil?

yes it was. i bought some stuff to make a case spreader after work last night so we will see how that goes

also is there supposed to be an outer axle seal on the front? It looks to me like I might be missing one but also the axle shaft doesnt have a smooth part where it looks like one might slide onto

[ghetdjc320]

This is a waggy axle right? What year?

[Jesse J]

waggy yes 1988. 

 

built the spreader and its not working. this isnt supposed to be the hard part

[Jesse J]

FINALLY I GOT IT

[scguy]

What was the trick?
