Topic: 94 v6 rear axle questions

[trinno]

ok i know nothing about toyota. I'm trying to get axles together to put under a tracker using the trail slayer kit from tt. What i need to know is the only differance between a truck and a 4runner 94 4x4 v6 rear axle is that one has leafs and the other coils??? and if anybody knows cant i cut of the coil perches and weld on leaf perches??

There were some 3rd members that came from the factory with 4.87 gears during those years that has no aftermarket support. (no lockers, no gearsets, etc)  It has something to do with the design or something.

That is not totally true, there is away to use any of the lockers in that housing. I do not know the details but I read about it on PBB a couple of years ago. It is something like using the 4 cylinder full locker (ARB, Detroit) with V-6 bearings. By the way it is 4:88 not 4:87.

Yes you can cut all the coil stuff off the runner housing and add leaf spring perches. A lot of people do that when the SAS the front on the runners.

yes, but it needs to be setup correctly by someone who knows what they are doing....

the 5.71 is the weakest gearset so its proper setup becomes more critical....

i know the 4 runner had antilock brakes in the rear. its just operated by madnetic switch that goes in a hole on top of the diff. just plug it with a stopper or weld it closed. and i think the e-brake set up is different. other than that and the obvious coil buckets, there is no difference

Some of the runners had anti lock breaks some didnt.  Also some of them had leafs and others coils.   The 4.88 diffs are offset inside which makes them Much more difficult to make other gears work.  There is a way to do it but it takes grinding and weakens the 3rd.   

As for the 5.71 gears......They are not what you would say weaker then other gears.  What makes them more prone to failure is the speed of which they turn.  Meaning to run a 5.71 on the street generates a LOT of heat.   This tends to wear them out faster.  They will stress the ring side pinion bearing.  When setting up these gears imo its a must to use a master install kit and make sure the carrier is in great shape.  Toyota carriers tend to wear out the carrier bearing sleeve making so the pinion bearing can be pulled off by hand vrs a press.   Go read Zuks page and read about it there.  He explains it better then I do.  http://www.gearinstalls.com/billyrear.htm
