gearing question (sigh)

[wiretie44]

hello all I have a 97 SR5 3.4 4WD Auto not locked it originally came with the 15 inchers... anyway I acquired a locked third yesterday with what i believe to be 4.30 but i need to confirm (exactly how many teeth should it have) and I have searched my eyes dry!!!!:ybrick: Also I did the spin test one wheel 20 revs 39 revs on the DS which tells me 3.90 gearing but in my seemingly endless searches most believe that was a 2WD setup,:shrug: but i digress. Also seeing as I will most definitely be re-gearing the front who do recommend I purchase the new gears from and any particular brands better than others. And while we all are here are the locker ECU for the tacoma and runner the same I know that they have different part numbers (89533-35070 runner) (89533-35060 tacoma) So firstly how many teeth on the gearset, where to go for new front gears, and ECU compatibility or availability . thanks

divide the number of ring teeth aby the number of pinion teeth

37/9=4.11
41/10=4.10
43/10=4.30 (not sure if this actual)

You can count the teeth on both gears and divide to fiqure ur ratio
