Sport 4.90 Gears
« on: April 14, 2017, 05:27:10 PM »
4.90 gears from a sport.  What years? 00-04? Looks like 3.5 and 3.0 were available in the sport of those years.  There are a couple in the local yards here in OKC.  Can I swap the ring and pinons fromthe sport to my 95SR?

As long as the gears come from a 3.5 and go into a 3.5 it'll work. I ordered mine a couple days ago from a 2002 3.5 sport. I'll hopefully be able to do a write up on this.

Thanks for the info Charly, I'm considering 4.90s as well unless I come across an SR with 4.63s and a locker.

With the Sport front center section: Does anyone know if the dash lights will still work when 4 wheel drive is engaged? Or will the front wheel lights flash?

For the rear: Since its a third member, am I correct to assume no gear lash has to be set? That would be a significantly easier driveway swap!

 The lights will flash when you engage 4WD, however you can wire the front detent plug into the T-case Detent for 4WD and it will just light up solid when in 4WD. It's very easy.

Here are the ratio options and your axle options, use this info to figure out your gear vs axle applications

   Taken from Outerlimits
 [color:"red"] T/case & Final Drive Ratio's
 [/color] 
Gen 1

2.3 TD = 4.875, 5.29
2.6 / 2.5 TD = 4.625, 4.875
2.5 TDI = 4.625, 4.875
3.0 V6 = 4.625, 4.875
t/case = 1.944:1 low range for 2.6, 2.3 TD & 2.5 TD, 1.925:1 for 3.0 V6

Gen 2

2.6 = 4.875
2.5 TD & 2.5 TDI = 4.875, 5.29
3.0 V6 = 4.625, 4.875
2.8 D = 4.875
2.8 TDI = 4.90
3.5 DOHC V6 = 4.636
t/case = 1.925:1 low range for 2.6, 2.5 TD, 2.5 TDI & 3.0 V6, 1.90:1 for 2.8 TDI & 3.5 DOHC V6

Gen 3

2.8 TDI = 4.90 5sp man
3.2 DID = 3.90 5sp auto or 4.10 for 5sp man
3.5 SOHC V6 = 4.30 5sp man & 5sp auto
3.8 SOHC V6 = 4.30 5sp auto
t/case = 1.90:1 for all

Gen 4
3.8 SOHC V6 MIVEC = 4.30 5sp man and 5sp auto
3.2 CDI = 4.10 5sp man or 3.917 for 5sp auto
t/case = same as Gen 3

Axle Data [/color] 

Gen 1

2.6, 2.3TD, 2.5TD & 2.5TDI (some) :-
front axle = 25 spline, 29mm diameter, diff = 7.25" diameter (low pinion)
rear axle = 28 spline, 30.5mm diameter, diff = 8" diameter
3.0V6 :-
front axle = 28 spline, 29mm diameter, diff = 8" diameter (low pinion)
rear axle = 28 spline, 30.5mm diameter, diff = 9" diameter

Gen 2

3.0V6 :-
front axle = same as Gen 1 except for NH & NJ auto has 7.25" diameter front diff (high pinion) NH & NJ 5sp man has 8" diameter front diff (high pinion)  [color:"blue"] some models with auto transmisions will also have 8" high pinion but will have smaller CV joints [/color]
rear axle = 28 spline, 30.5mm diameter, diff = 9" diameter

2.5TDI :-
same as NH & NJ auto

3.5V6 & 2.8TDI :-
front axle = 28 spline, 29mm diameter, diff = 8" diameter (high pinion)
rear axle = 31 spline, 33.5mm diameter, diff = 9.5" diameter

Gen 3

3.5V6, 2.8TDI, 3.2DID, 3.8V6
front axle = 28 spline, 29mm diameter, diff = 8" diameter (high pinion)
rear axle = 33 spline, 36mm diameter, diff = 9.5" diameter

Gen 4
same as Gen 3

Note :- Mitsu factory Aisin manual hubs (found on some models - Gen 1 or Gen 2 base models & Tritons) are interchangeable and will retrofit to all Gen 2 models with super select.
These will not fit to a Gen 3 model as they run solid one piece hub flanges (non-removable).

Looking forward to a solid write-up of the swap procedure.

A list of items to remove in order would be helpful for those that have never fully removed the front axles/differential!

How does one identify which front diffs do not have the disconnect?

 The Sport disconnect hits the Montero oil pan.

My experience with disconnects front ends has been with failures. It creates a week point in the axle. They also work with vacuum from your motor to engage. The vacuum line can be damaged or come lose as well as the actuator or diaphram going bad which will cause you to lose 4 wheel drive.
