i just bought my first toyota 4x4 it is a 81 with 22r i was just wondering how strong the axles are it has 33-12.50s on it now and was wondering if they would hold 36-12.50s with my stock axles im hopefully getting gears soon thanks for all the great info in hear

 

you don't have to worry about breaking anything if you run 36s because the engine doesn't have the powwer to turn the tires with only 3.90 gears

 

Save your money and do the tires, gears, and lockers all at once.

 

you might eat some birfields if you wheel it hard...

 

thanks for all the replys im getting the tires for free thats why i asked and what is a good gear for wheeling and dd i was thinking 5.13s is that to low i dont go on the freeway

 

usual recommendations for 22r (re) equipped toyotas are:
33's = 4.88 gears
35's = 5.29 gears

5.71's are available but seem to have a mixed review. 5.13's are not available. 5.29's with 36" tires would work great for a daily driver/weekend wheeler. I eventually plan to go 5.29's with 37" tires.

That being said, bigger tires/lower gears the truck is not going to be any real speed demon or gas mileage champ. Probably 18'ish. ALso consider upgrading your brakes...your truck is designed for 28" tires.

 

i have an '81 with 36's and 5.29's and a stock 22r with about 300k+. it turns em easy. i used to have an '88 with 40" swampers, 5.29's and a stock 22re with over 200K and again it turned them easy. i never broke a birf or axle either. im not easy on my trucks by any means i just dont hit holes really hard. my philosiphy,"easy in power out". in my opinion i woulnt go to 5.71's because the pinion shaft is way small and ive heard they brake easy. hope this helps.

 

my 83 has 5.29 and Im running 35x16x15 boggers on stock axles
