But a 4runner is a bitch to get big tires and lots of up travel in the rear, while still having room for a family and large fuel cell. Truck cab has more flexibility for packaging.

Fair enough

I just saw a youtube video where a guy was creating lots of uptravel for big tires in the rear of a 4Runner - I'll look for a link.

@Hank is working on his brothers 4th gen too. Problem is keeping the cargo space available, especially with two small kids. A dcsb allows more bed space with less interior intrusion for bigger shocks while retaining the in cab comfort.

1st gen tundra (non-double cab versions) are basically the same size as a 2nd gen tacoma. I just want a double cab that isn't wide as fuck.
Sounds like you need more truck :deadbanana:
I do
You got two kids. You see the struggles I got with one and two dogs
Yep, it's not easy to pack light as it is, and with more up travel, more fuel, and less cargo room, its going to be a bitch to pack light enough for longer trips. I may have to cave and finally buy a roof rack...

Reviving this to see if anyone has any suggestions for me or experience with anything similar.

I just replaced a broken ADD stub with a manual hub tube. Comparing the two this will likely make an insignificant difference in strength between the two shafts so i am looking at options for when this shaft breaks.

I like cheap stuff and getting blind internal splines machined is not - so i am trying to avoid this but strengthen a solid type intermediate shaft for the 7.5 front

My best current plan is:

find a 1.1’ major diameter 27 spline chromo shaft to cut down and weld to a stock outer section, sleeve with chromo and plug weld it all over. Plan would be heavy pre and post heat and send it off after it is fully welded for a heat treat to relive as much stress as possible.

Has anyone had experience or ever Seen anything similar? I have never seen someone weld an Axle then heat treat to avoid breaking ait at the weld

Another important question is - is anyone falimiar with what material Toyota would have used for these stub shafts? I don’t know if they like 10xx for their axle stuff or if there is any chance they would use 4140 or what? I wold like to figure out how it would heat treat compared to the 4340.

As far as options for the chromo 27 spline - the 7.5 front is the only place I can find this size 27 spline. (D30 and 27spline Toyota birfields are both larger) This means my options for a shaft are:

chromo LT shafts for stock cv outers (BTF and TC sells these) -
custom cut splined shaft

any thoughts on why this is a bad idea?

Anyway, the exact how's and why's of heat treating are beyond my pedestrian knowledge of metallurgy.

I however can say with reasonable certainty that welding onto a hardened shaft, regardless of pre/post heat or heat treatment after wieason for doing so i the first place.





















































































































































































































































































































































































































































I know of a few instances where a CV broke at the d same time as the stub shift. I was present when a friend broke his stub shaft but his cv was still intact.

Just run what you got. Fix it when it breaks.
