Toyota questions...

Recommended Posts

Hello. I know nothing about toyotas...do they have rear ends where the ratio is 3.9? If so, where can I get one?

I'm thinking of a project with a Subaru transmission to be used.

You gotta be a bit more specific. I know 1973 Toyota Corollas with a 1.6L engine had 3.90 gears in the back, the ones with the 1.2L engine had 4.10 gears.

When you go to the dealer to do your research, you will find, that there are so many different Toyota rear axles, with different ratios that your head will spin.

Exactly what I meant. (Knowing nothing about Toyotas)

I want a solid axle with 3.9 ratio.

the majority of the truck axles come stock with 4.10 diffs. if you swap a legacy diff up front and a transfercase in, you could use the stock truck axles.

 

as for the toyota rear diffs from the trucks, all you need to know.... it appears 8" diffs come in 4.10 and up, 7.5" toy diffs came in 3.9. options with an 8" rear diff are innumerable, i'm not sure about lockers and such for the 7.5" diff

info from the http://www.pirate4x4.com/forum toyota FAQ... don't bother asking any questions over there unless you have thick skin...

 

 

Toyota Rear Axle Widths:

55" wide, '79-85 4wd trucks/4runners - 6 Lug

58" wide, '86-95 4wd trucks/4runners - 6 Lug

56" wide, '79-95 2wd Trucks - 5 Lug

60.75" wide, '95.5-up Tacomas/4runners

66.75" wide, '93-98 T100 trucks

 

Differentials – Gearing

 

Gearing..... with a 4 banger and single case

stock 4.10= 31 or smaller tire

4.88=33 inch tire

5.29= 35 to 38 inch tire.

5.71= NOT RECOMMENDED FOR REAL OFFROAD USE

83-older 4.11 diff's are 37/9 and are 8in 4cyl style diff's, in 84 they switched th the 41/10 ratio, any time you have more teeth to a pinion the stronger the diff will be, reason being: more tooth contact/more teeth contacting the ring gear at one time.

This is the same reason 5.71's are very weak, 6 teeth, 5.29's have 7, 4.88's and 4.38's have 8, 4.56's have 9 and 411's have 9, 410's have 10, and 390's have 10

If you have the axle code of your vehicle, it is easy to find out what size differential, what ratio, and what pinion set-up you have. This will also help if you are hunting for a particular unit off another vehicle. The axle code is in the vehicle ID plate under the hood or drivers door. The axle code is 4 digits: a letter followed by 3 numbers.

 

Example: G292 = 8.0" 4.10 final ratio 2 pinion

Code:

 

1ST R&P SIZE 2nd/3rd R&P RATIO 4th DIGIT PINION SET-UP

F = 7.5" 07 = 3.900 2 = 2 pinion

G = 8.0" 08 = 4.110 3 = 2 pinion LSD

10 = 4.375 4 = 4 pinion

14 = 4.875 5 = 4 pinion LSD

25 = 4.556

28 = 4.300

29 = 4.100

31 = 3.91

38 = 3.42

43 = 3.56

54 = 3.90

66 = 3.07

.

.

 

Code:

 

Ratio Ring/Pinion Color Crawl:Ratio

3.42 ...42/12... Purple ...31:1

3.90 ...39/10... Red... ...36:1

4.10 ...41/10... Pink.. ...37:1

4.11 ...37/09... Orange ...37:1

4.30 ...43/10... Blue.. ...39:1

4.37 ...35/08... Green. ...40:1

4.56 ...41/09... Yellow ...41:1

4.88 ...39/08... White. ...44:1

5.29 ...37/07... None.. ...48:1

5.71 ...40/07... None.. ...51:1

driving or building you sink way to much money way to quick

 

soob or nonsoob you'll sink a lot of money. it's the nature of the beast, and the money has to get forked up to 4wheel hard. :rolleyes: i don't think i'm even near what i've sunk into the subaru in the toyota yet. it's fairly close though. the subaru has over the years well over $7k. the cost to strength ratio though...

that's a very conservative estimate, and doesn't include the multitude of tires, consumables (ie replaced axles and stubs, trannies, differentials) or repairs over the years. just the straight to what it is cost. otherwise i'd be sitting here for days trying to run it all up. projects eat money, but in the end they can be worth it.
