I have a 01 Ranger Edge.. .and i was curious if i had a limited slip diff?????? its the 4.0 4wd 4dr. thanx for helpin a newbie.....

 

my guess would be yes but check the sticker on the driver side doorjam for the axle code. it will be at the bottom of the sticker.

I have a 99 3.0 and the door sticker says axle code 97. Does mean that 97 is for both 3.0 and 4.0 4.10 ratio non limited slip?

 

Another way to tell is to jack up both rear wheels, put the truck in neutral and manually turn one of the rear wheels while watching the other side. If the other wheel turns backwards, you do not have limited slip. If it turns the same way, you do.

 

generally if there is a letter and a number in the code, it is limited slip, if there are 2 numbers it is non limited slip.

 

on my 02 ranger if you look at the reat axle tag it will have a L on it for Limited slip

 

okay i just looked today and it is and r7 so here is another newbie question.... whats the difference between the 3.73 and the 4.10.... Whcih is better, Wose, cons ,pros?? all the good stuff thax a lot for everyone that is helping me.. also does everyone 01-04 ranger have a 93 mph limiter on it???

 

yes all rangers have a speed limiter at 93mph from what i know on the 01-05 well the gasmilage is wourse on the 4:10's because it is a lower geer and gives you more toque and the lower the geer # the higher the geer is and will give you more top end(please correct me if im wrong) here is a post from franken truck on a nother thread showing the diff in ring and pinon size and tire size. might be helpful in understanding

 

I'm confused. My truck is a 02 Edge with the 3.0 and 4x2. It says I have axle 97 so that is a 4.10 non limited slip but 4x4 according to el conquistador. Also with that combonation I would think I could spin the tires on dry pavement and I barely get a squawk.

Here is a link for the vin decoder; check the engine code and see what it has for the rear end code

I need a vin decoder for the 2002 model year, because the 2000 you posted a link to gives me incorrect information such as the axle code and the VIN numbers don't match up

 

Here is one for later Fords

This link dosen't work??? but it is the correct address..

This is out of the 2002 Ford Manual:

Ranger

86 — 3.73 non-limited slip.
87 — 4.10 non-limited slip.
89 — 4.56 non-limited slip.
F6 — 3.73 limited slip.
95 — 3.55 non-limited slip.
R5 — 3.55 limited slip.
96 — 3.73 non-limited slip.
97 — 4.10 non-limited slip.
R6 — 3.73 limited slip.
R7 — 4.10 limited slip.
KA — Electric vehicle (no ratio).

The axle code is on the door sticker.

 

Thanks Rockledge, that clears it up for me.

 

Well I am still confused because I can lay a burnout with BOTHtires. Maybe the dealer changed it because the dealer owned it until I just got it
