Official axle rating for the 80?

[e9999]

is there some official (and perhaps documentable) rating for our 80 axles?

As in some rental yard guy who says "you need a 1 ton axle to tow that Bobcat" and won't take the "TLC is always best" for an answer...

Or, as in late at night in the bar "my axle is stronger than yours..."

And, of course, for my personal enlightenment!

anybody knows?

in trucks usually the 1/2 ton 3/4 ton and one ton ratings are more about the springs, although axles and sometimes frame are proportionally larger as the rating increases, the LC being a coil sprung SUV would be equivalent to less than 1/2 ton, the axle itself is very strong through, it would cary much more weight that the springs would, the rear being full floating (usually only found in 1 ton and heavy 3/4 ton trucks) also increases it’s load carrying ability

I believe Cdan usually pipes in at this point and says the LC is rated for 500lbs tongue and 5000lbs total weights and leaves it at that. No mention of pickup truck ratings ever.

You're the first E.

eh, what can I say, I'm curious about these things...

If you took the bearings alone at looked at the size of the Full Foating type of rating the bearings are good for it would be equal to 6000lb rating(single axle). Not to say that is the rating. with the right springs and shocks it would be a 1 ton easy. But I truly do not know the rating. What is the intrest for? If I may ask. later robbie

as usual, Robbie got the inside scoop. Good to have you around, bud!

Interest is just curiosity to see how our axles compare to the (not competitive obviously) competition... (and the occasional rental yard salesman that needs to be straightened out...)

[As far as my axle is concerned, it is definitely stronger than everybody else's... and don't argue with me, please, I don't take rejection very well.... sniffle... ]

If you are in a situation where you need to "prove" that the axle is heavier than your average Corolla, explain that the Rear axle is a full-floater like what is used in the Toyota motorhome chassis rear axle and that it shares some of the same components with that axle including the (4) wheel bearings. In adddition, it is disc instead of drum and the differential is significantly larger than the one found in the motorhome chassis


I just unloaded Pappy's new rear locker diff off the air freight truck this afternoon. The box said 97 lbs (just the chuck and actuator)

I think the figures are right on the door/door jamb sticker. Look for:

GVWRR - rear axle
GVWRF - front axle

I could be wrong, but I'm not getting out of the MaxiCush Barcelona Landau King bed to take a look - heh.

I Know that in other countries the rear cross member is rated for 10k lbs for towing. just by bolting in a ball or pintle hook. The 100 series rear diff is real close to the same size as a dana 60 (11 inch ring gear). The stock rear diff in a 80 is 9 inch but measures almost 9.75 from outside to out side of the ring. As for the front the reverse cut is called a 8 inch but measures almost 8.5 inches. It is real funny how numbers get attached to things. The truck is stout no doubt. Just recently I hauled some sand for a sand box for the kid. I did it in tow loads. My truck sets ont the 6 inch springs and I have a fuel tank and drawer system. I then loaded 1000lbs 1st load, 1200 2nd load, between the center seats (folded up) and the drawer system. Truck only droped about 3/4 inch and handled just great. still stoped fine. It is a matter of loading the vechicle properly. In the form that I have my truck set up it weighs 6500 lb with out the sand. The only negative to all the weight is the loss of fuel milage. later robbie

LOL too funny...that's what I love about wireless phones with a mute button.

I have always thought of this comparison more like "well my built mini-truck/cruiser (40series) axles are comparable to a Dana 44".......... but i have never heard of anyone actually comparing 80 series axles with say a Dana 60. I would be interested to hear what some of the board members would compare the 80 axle to a 44 or a 60. OR even a built Front 80 series axle's with the Birfs treated and Chromoly shafts?

 

[cruiserdan]

I have had Dana 60 and 70 and 71 series axles apart. In my opinion the 80 series Cruiser rear axle is on par with a Dana 60 and possibly approaches a 70-71. Of course it is important to point out that the Dana set-up is completely different than the Toyota version.
