Curious about best apparatus to put in 3.07 middle gears

[Reworked LMTV]

Hi Guys,
Well the axles went in for balancing yesterday. Tiger Tool helped a lot. If you use one you must take the zerks out first. They get destroyed.

I need to drop in the 3.07 gears. Just curious about using a gantry and chain hoist vs. engine hoist vs?

I am putting in a locker at the time. Count the number of turns and mark the star nut position? This is what I have seen.

Use a floor jack or transmission jack.
Ring and pinion needs to be set up by someone who knows what they are doing to include verification of gear contact area.

The guy that sold me the locker said to scribe mark everything before taking apart to install the locker and then put it all back together using the marks. I didn’t personally do it I had a local driveline shop do it but it came out fine that way.

I just used a floor jack, and it worked ok.

Did you stabilize that massive chunk with anything?

Nope. It sat in the saddle/dish on top of the jack. One person kept a hold of the gears, and one slid the jack.

It would probably work better with a transmission saddle on the jack, but it never felt overly-precarious. (And I'm not the type of person to do blatantly stupid things that are unsafe. If I had felt it was going to end poorly, I would have just gone and bought the transmission jack.)

putting in a locker is easy and requires no setup. just mark where the side adjusters were and put them back there. have done hundreds that way.

I am assuming you did a 4x4, not the 6x6. The 6x6 chunk in the middle is massive.

Correct, for a 6x6 you will probably want a transmission saddle, but I still don't think it will require anything fancier than that.

The 6x6 center diff is precarious even on a big transmission jack. the shape just does not lend itself to sitting on anything.

I unloaded an intermediate differential from an F250 once. With three people, it was more of a controlled fall.

For my install, I plan to have the bed off and then do a chain fall from above. Maybe use a motorcycle jack from below.
