Lol full air ride be best...
The number beside the "drives" is the rear axle..87XX number, Max I can gross it is 10,000lb.. Timbrens where nice at that weight.. They suck at any thing less. Alot rougher with them on then just springs... And completly un noticeable with no trailer..
Roughly a 25,000lb trailer

Part should all be here today. Cleaned up the diff housing and axle tubes last night. It was nasty. Behind the carrier bearing preload adjusters was some nasty sludge that was piled up. Had to get a spoon and scrape it out. Soaked everything in WD40 to loosen it all up then sprayed it all out with brake clean. Clean as a whistle now.

Let us know how this works out. My buddy had an 08 Dodge that had this helical locker in it. One wheel peel everywhere in the rain and snow. I've wanted to do something to the rear, just not sure which way to go

Mike not sure if this has been mentioned and wish I had thought sooner..

Buy a cheaper inner and outer pinion bearing then ream the inner area where it slides down the pinion with some resistance ( not press on but not falling off, just hand tight).. Use these bearings to figure out where your shim stacks need to be then once your ready for final assy press the new bearings on and your done. Much easier and faster than pressing bearings off and on constantly.

I've got a set Id send ya if I had thought about it sooner.

I will vogue for the dodge locker.. The red truck I got from Jesse had one. I loved it.. Never knew it was there until you wanted to spin the tires, never once let me down. You could go from a dead stop to a 4k clutch drop into donuts.. You could sidestep the clutch turning out of somewhere and walk it sideways every time.

Time for a spool lol, Honestly I can't believe how expensive a spool is for these trucks. I wouldn't have bought one when a locker is like the same price. I just got off free by welding mine.

Guess your just holding your Breath for the ups guy now.

 

[zf>allison]

I don't think you will have one problem with the aam for street strip use, off road I'd use something else.

 

[melms23]

A bought a whole low milage axle out of an 07 dodge for 600 thinking I could use the axles also. Which is not the case.

As for spinning, going straight is never an issue, and when dry it will usually spin both depending on conditions.

Only time I felt it was much different from the g80 is in snow and rain. Never felt undrivable by any means however.

Hopefully this isn't the case. My dodge friends have all loved the factory locker in their trucks. But then again, they're all mostly 600hp and under. Not sure if hp will affect how it reacts.

Someone did mention that the case isn't hardened like a Detroit true trac is so after 50,000+ miles, the case wears a little and the locker stops reacting like it used to. Not sure if this is actually true or not. Either way, 50,000 miles would be 8 years for my truck considering I only put 6500 miles on it last year.

This is what I'm hoping:woott:

I got an Eaton true trac in my 79 wagon.. It behaves just like Corbin mentioned

Why not just use the standard crush shim? It's not that hard to figure out and you don't have to press bearings on and off either. Don't forget about the depth shim on behind the inner bearing. All you do is assembly it with the new crush sleeve without the seal on. Get it started with a pipe wrench on yoke then you can use an impact to tighten the rest of the way. Tighten it check preload tighten check preload etc. once oh have the right preload mark the nut and count the treads to remove the nut. Then pull yoke install seal, yoke and nut back to marked spot

Everything showed up this afternoon, took it to my work and pressed all the bearings on to the carrier and pinion.

Built this fixture out of the old bearing races to press the new bearing races into the diff housing. Hit it with an impact and they sink right in.



Got the pinion in and snugged up. Went and snagged this in/lbs beam bar to set the pinion bearing pre load. Didn't want to rush through it so I called it a night.

Do you have the stock steel cover on it? Now would be the time to snag an aluminum AAM cover from a dodge.

 

[mike diesel]

Yep just the stock steel cover. I'm looking into other covers right now. I saw the OEM finned ones.

Put it all together today, the bearing/seal kit came with everything except the pinion wear sleeve. Started filling the diff with fluid and it came pouring out of the pinion. Had to run down town to snag the $8 wear sleeve they didn't include. Luckily the yoke came back off easily. Oh well, it's all finished up and seems to be running great now.

Spins both tires no problem. The real test will be to see if It will let me do donuts, the g80 wouldn't and I'm pretty sure the last time I tried is when it exploded. Going to drive it to work over the next couple days then pull the diff cover back off and make sure everything looks good.

What are you calling the pinion wear sleeve? You talking about the seal? If so you set the preload without the seal only or redo it when you had that installed? Because preload is to be checked and set back same spot with zero seal. You do it with the seal, and your preload will be too little

[mike diesel]

I set pinion preload with no seal. There are 2 seals. The seal that you hammer into the diff housing and then a seperate one that slides on to the yoke. They call it a wear sleeve.

 

[whitetrash21]

Not to thread jack you, Mike, but does the back of the tcase have a similar seal setup?? One that's pressed in and the "wear seal" on the back of the rear housing?? Or is it one seal??
