Rear Ratios

[Blazerbill]

Just picked up 99 LT s10 with GU6, 12:41 3:42 front ratio,GT4, 11:41,3:73 rear ratio should'nt the front match the rear or vice-versa for bet overall 4wheeling ?

 

I know fords have had some with diffrent setups without any problems.

What????????

 

The front and rear gears MUST be the same (only slight exception is trucks specifically meant for a straight line mud bog and nothing else)

 

Why do you think you have different gears?

I know i have them, changed lube in rear looked @ #s while cover was off as far as front diff had to remove it to get to oil pan to replace gasket and decided to split it open to check bearing condition since the amount of lube drained out was low and black. (all looks good but numbers didnt match)

Good thing you never put the truck in 4wd....

 

You need to regear one of the diffs. Or you'll blow something up when you engage 4x4

I did before i payed for it but no-go bad solenoid that locks front in so i know what i'm doing this weekend.

 

Thanks Matt

no problem.

 

for what its worth i'd regear the front diff to 3.73s instead of changing the rear to 3.42s. The front diff is also easier to regear (IMO at least).

 

 

I wonder if the previous owner "disable" the actuator so you wouldn't know ... might want to check the voltage

I doubt the truck actually has different front and rear gears. Somebody made a mistake somewhere.

.... like possibly counting one extra or one less pinion tooth than whats actually there.....

I wish it was this simple,thanks for your input but i tought my parrot to count to 50 and does this pretty well, as so can i and more,

does not 12:41 translate to 3:42 if one was to divide 41 (ring gear teeth) into 12 pinion teeth count . as does 41 divided into 11 = 3:73

I thank you once agian, you saved me a few hours work removing front diff had i installed after doing pan gasket.

I'm assuming you're going to regear the front correct?

 

If so, and you didn't put the front diff and axles back in yet, don't drive the truck. You can not drive without the CV axles installed. They hold the front bearing assemblies together.

So do I. Unfortunately, it does appear that you have a bastard child on your hands.

 

That's a pretty smart parrot.

Indeed regearing to 11:42.........my weekend will be fun.

RPO code in glovebox reads GU6, 3:42 so vcm/pcm will need reflash know of a good reflasher for diy ? Edit: Spelling

 

 

Any thoughts on iron case to replace aluminim?

For the price i payed for him he should clean his own cage.
