There is a complete rear axle for sale with low mileage close to me. The truck is gone but the drivetrain is all there. Its from a 2002 2wd with a 4.0 motor and automatic transmission. There is no tag on the rearend. Is there a guide or way to tell what gears and or limited slip could be in it? Thanks for any help on this.

Cheers

there's only 2 ways to tell i think,1.)sticker on the door jam of the truck,2.)tag on the axle .but seeing how you don't have either one i'm not sure

 

Open it up , divide the ring teeth by the pinion teeth, or......spin the wheel/pinion, count the turns of pinion/wheel and divide. Not sure about Ford OEM, buts ome gearsets also have the ratio stamped on the front of the pinion.

 

Put the axle up on a pair of jackstands.
Turn the pinion shaft in one direction while a helper watches both axle hubs.
If they turn in opposite directions from one another , it's an open diff.

Now set the pinion yoke with a bearing cup at 12 o'clock , mark it at the top with a sharpie pen.
Without moving the pinion , mark an axle hub at 12 o'clock.
With your helper watching the hub , count the turns of the pinion it takes for the hub to make exactly one revolution.
Just a tad over 4 revs = 4.10
3 and 3/4 revs = 3.73
Those are the most common.

 

Thanks guys for the help.

There was some tags on the axle.
They read:
V375B and L55.88 1k16
Does this make any sense?

On my 91, it said the ratio right on the big gear on the left, 3.55 gears O.O

 

===================================
It's a 8.8 with 3.55 L/S..................does it have the shock mounts for a Ranger? 8.8's weren't very common in 4X2 Rangers is why I ask......sounds like an Explorer setup, but then again..........anythin is possible!

 

I thought all the 4.0s had the 8.8? But I may be wrong

 

Thanks guys I am going to pass on it.
I need a 4:10 ratio.
