5lug Axle Info

This thread isn’t finished, i am working on it but hit post by mistake. If you have any more info let me know so i can add it in
This thread is to give everyone a good understanding of 5lug axels and how they are different then 6lug axels

Between 95-15 3 axels different axels were found under our trucks, the 7.5”,8.4” and 8.4” (for 2nd gen taco). All of these axels were set up for spring under axel (sua) vs the 6lug spring ove axel (soa). All used a softer 2 leaf pack vs the 6lug 3leaf pack. The e break setup was different from a 6lug in that the 5lug cable just went strait into the back of the drum while on a 6lug in soan across the axel and went to a mechanism on the outside of the axel.

Toyota 7.5” axel 86-04 pickups and tacomas
This is the smallest of the 3 axels. For tacomas this axel was found in 4cyl 5lug tacoma. It had a 27 spline count. It came with 2 different gear ratios Auto trans 3.58 manual trans 3.42
Pre tacos had a more narrow axel but the 3rd was the same.
There are a few options out there for different gears and lockers.

Toyota 8.4” axel (1st gen tacoms)
Found in v6 5lug tacomas, the axel is similar to the 6lug version and will take all the same internals. Came with a couple different gear ratios, s runner 3.15,

Toyota 8.4” axel (2nd gen)
In all 5lugs. 2nd gens axel is 2” wider on either side and use different mounting points then 1st gens. They came with manual trans 3.31 auto trans 3.53 gears, but accept the same internals as the 6lug, it will even take the same diff from the earlier 8.4”.

I should note the 6 lug elocker axle shafts are 1/2 in longer than 5 lug and I'd assume 6 lug non elocker axle shafts. This is why Im 6 lug in the rear I did try to swap them but no game. Also 2nd gen 5 lug with auto is 3:53 gears.

 

The elocker housing is different then a non elocker housing.
But non e locker houseig should be the same as a 8.4” from a 1st gen other then length and the spring perches

 

Yup I just wanted to clarify in case someone decided to follow what I did.....The locker is so worth it though lol

 

Why you go with a new axel vs just putting a arb or Detroit in it. Would of been simpler

 

I got the whole axle for $400 and the new leafs for $100 so around $550 with some tools I didn't have, I got a locker with a slightly better gear ratio. I was looking at an arb but you cant beat that price lol

 

Damn you cant even get your 3rd regeard at ecgs for that price lol

 

An arb alone is close to a grand and I wanted a selectable locker still. I will still regear eventually but for now its got enough pep for that I need. (Also I may have a mk3 supercharger to go in )

 

Ok im reviving another old thread but here we go, im looking to swap out my axle on my 5 lug tacoma. Im trying to figure out what gear ratio i currently have 96 tacoma V6 auto, but want to convert it to a manual and swap out the axle with something bigger but want to know what is compatible with what, tried searching and keep finding info on 4 bangers and 6 luggers.

 

Are you possibly saying that I could take a 5 lug axle from a 2wd 1st gen tacoma with a V6 and swap out with 6 lug axleshafts from a 4wd 1st gen tacoma with a 4 cylinder in it?

 

Yes and no.

yes you would make it a 6lug. But you will end up with a SUA 6lug axle when you need a SOA 6lug axle.

you will also have some weird gear ratio in the diff.

but other then that its just a normal 8.4 axel

 

Actually, what I'm trying to do is SUA. So this would be what I've been looking for. From what I've read over the past several months, with SUA you get a better ride and less axle wrap. Also I want to lower my rear a few inches.
