Okay im new to the forum and this is my first post so forgive me if this has already been addressed. I've got a 96-02 tacoma axle with elocker under my 88runner. I've put in 4.88's but when I was installing the new axle I discovered I have a tacoma axle on the right and a 4runner axle on the left. I discovered this when I went to install the ebrake. It was a Craigslist deal and I overlooked it. Stupid I know. I went to the yota yard and got a non abs tacoma axle but it vibrated when I put it in so I removed it. My question is as follows. What axles fit in the taco housing setup for the elocker and abs? Would anyone recommend a spacer to fill the void with the non abs axle? Thanks.
