I am planning on changing my diff fluids over to royal purple. I am 99% sure I dont have a limited slip rear because with one tire on ice, and the other on pavement it only spins the one on the ice. If i hold the brakes, it will spin both, and if both have even traction it will spin both... so I am asuming it doesnt have a lsd.
I looked in the glove box and on the sticker it said something like this:
gear ratio: 3.92
rear axle: corporate 9
rear differential: anti spin

So what is an "anti-spin"?? And do I need a friction additive with it?

Also, is the 3.92 a lower/towing gear or is that the standard ratio?

thanks

 

anti-spin is a lsd, limited slip differential, same thing just a different name.

 

Casper is correct, you have a LSD, the reason it doesn't work the way you think it should is that the AAM LSD is just a sorry POS...

 

SHET! that is not what i wanted to hear... so do the clips fall out of the AAM lsd too? should i get a trutrac and use this one as a boat anchor?
so how come it only spins one tire on ice?? is it really that big of a pile?

 

i was told the stock LSD is a torque-activated LSd. meaning it's only an LSD is very specific conditions.

that said, even with 160K miles, you can still hear/feel the tire chatter in turns on our hemi.

 

The "Chrysler Corporate" and AAM axles/differentials are one and the same...

 

so if the clips fall out, how much damage do they do?

magnet- you said you have 160000 miles on your lsd, have you ever had any problems with it? i never hear mine chatter...

should i wait for this thing to crap out, or change it now?

I wish I hadnt asked if it was an lsd... now Im always going to be worrying about it...

 

Wait a minute -- "...one wheel on ice, the other on dry pavement, it spins the wheel on ice..." is a peg-leg. If I put one rear wheel on wet grass (not much ice here in Florida) and the other on dry pavement, the truck goes.

 

i noticed before i installed my geas that lately when i had turned corners something was not right because i think oh the wheels was hopin! and as i said in last threads about gears , they broke in and clips were broken....i m not exactly sure if they go hand and hand though

 

It's my dad's truck (i drive the Dako), but we've only had the lube changed...no actual servicing. Like i said, on the loose-surface roads, you can hear the inside wheel chatter-spin like it's locked up with the outer.
