What is my differential gearing??

Wanting to slap in a locker but don't know how to tell what my gears are and what gear ratios the 2nd gen even came with.

 

All V6 6-lug models came with 3.73 axle ratio.

 

Park the truck on level ground. Put it in neutral. Jack up 1 rear wheel. Turn the tire so that the valve stem is straight down. Make a mark on the ground that lines up with the valve stem. Have someone turn the tire exactly 2 turns while you watch the pinion yoke. Count the number of turns of the pinion yoke. 3 3/4 turns would be 3.73. If you had something like 5.88 it would be just shy of 6 turns.

 

Why do u rotate twice?
Wouldn't u do it once?
JJust asking

 

This is correct.

 

I was under the impression that all the autos came with 3.73 and the 6 speeds came with 4.10's

 

Because you're only turning 1 wheel. If you want, you can jack up 1 side turn it once, set it down, jack up the other side and then turn it once. Same results.

If you already have a locker, posi, limited slip, spool, etc., then you jack up both sides and when you turn 1 wheel the other wheel will turn also. In that case, you just turn 1 time.

 

No.

v6 6lugs regardless of trim and transmission all came with 3.73's

i4 6lugs regardless of trim and transmission came with 4.10's

/thread

 

Gotcha - Thanks

 

^^This.

I4 5 lugs have 3.31 manual, 3.58 auto.
X-Runners are 3.15

According to literature, Prerunners are also 3.58 if 4 cyl auto

 

wrong...... like stated... ALL 6 lug i4's are 4.10's regardless of trim transmission or prerunner / 4x4

 

Maybe the brochure has incorrect info... it's been known to happen in the past!

 

Weird, don't think i've ever seen or heard of a 4 cyl 4x4 / pre runner with the 3.58

 

yeah that brochure is wrong for sure.

no way an i4 would be happy pushing a prerunner with 3.58's.
