what is the drum to drum width on a 1985 toyota 4x2 7.5" rear end?

i have a 94 ford explorer rear drums... 3.73 lim slip d4 ford 8.8" rearend...

i am thinking about doing a direct swap into my toyota... this same thread will be posted on the ford explorer board as well....

also, if i remeber correctly, it has a center diff and not offset correct? now what are the positions of its spring pads located... like how many inches in from the sides of the drum? the toytoa jsut has rear drums... the explorer has abs with rear drums... also, what about a custom ebrake setup for this? i would assume i would have to either lengthen or shorten the current e-brake cable
i also know i will need different brake lines rubber/hard and such

what about in the pinion mount flange from the driveshaft to the pinion?

Just curious....whats the point???

upgrade in strength, replaces the whole axle with one that is 10 years newer, already has 3.73 gears and limited slip... same bolt pattern as well.....

why dont you find an axle out of a mid 80's "1-ton" toy 4x2, correct me if im wrong but those axles had a 8" 3rd member out of a 4x4 and it was still spring under, with 5 lug if im not mistaken

Swapping a 7.5" Toyota diff in place of a 8.8" Ford is most definately a step backwards in strength. Find a 8" from a ¾ or 1-ton or from a later V6 2WD truck. Even then, the benefits are negligible if at all.

jimbo74

not sure if i read this correctly, but are you saying the ford 8.8 is weaker than the toyota 7.5? i was actually wanting to put the 8.8 in as a replacement to the 7.5

out here, the junkyards with anything good is vary scarce.....

i think you've got it backwards there buddy

i take it your gears are 3.73s? there's quite a few different ratios for the 7.5 in 1985: 3.07, 3.42, 3.58, 3.73. i think the only problems you'll have with the 8.8 are that it's lug pattern *could* be different, and you'll need a new driveshaft or some way of mating the u-joint up

jimbo74

the ford uses a 5 on 4.5 lug pattern, just as the toyota 4x2 trucks

the explorer rear has 3.73s with a Limited slip

i might just keep the toyota axle.... and just put a locker and 4.10s in it.....

Yup, I had it backwards. For whatever reason, I thought you swapping a Toyota 7.5 into an Explorer (believe me I have seen this done too). My mistake.
