can anybody tell me what the differances between a two wheel drive rear axle and a four wheel drive rear axle. i want to know if i can use the houseing from a two wheel drive to do a leaf conversion. for my 4 runner.

 

Smaller axles, smaller ring and pinion, narrower, spring under, etc.

I would look for a 4WD housing, or endure a lot of trouble.

 

all that and the 2wd axles are 5 lug.

 

okay can i use the axles and third member out of the 4 wheel drive rear end. how much narrower is the two wheel one than the four wheel one. im only asking cause i have a trailer thats made out of a 90s pickup thats two wheel

 

Forget about using any part of the 2wd axle for a 4wd. Whats wrong with the current axle in your 4runner?

 

nothing is wrong with it i was just woundering if i could use it since it is for a leaf spring setup and my runner has 4 link

 

2wd axles with a F code are 27 spline with a 7.5" ring gear 5 lug
2wd axles with a G code are 30 spline with a 8" ring gear 5 lug (non-dually axle only)
4wd axles are all G codes and are 30 spline with a 8" gear 6 lug

2wd axles with a G code will accept most 4wd G code third members**

**Not 100% sure but from what I have learned the depth of the 2wd G code axle housing is shorter than a G code 4wd axle housing. What does this mean? The ring gear may hit the back of the housing of a 2wd G code if you use a 4wd G code third member but this has not been confirmed so far. I have a 2wd G code axle housing and a couple of 4wd G code thirds and I will see if this myth is true or false.

how do i tell what housing i have?

 

The one that came with your 4Rnr will correspond to the Axle Code on your Vin plate in the driver side door jamb (Depending on your year). It is a 4 digit code starting with a letter. My code is F372 because I own a 2wd so yours should be G---. It should be in the bottom right area of the sticker
