I tore my Tacoma E-locker rear axle apart today. When I took out the bolts for the diff all of the studs came out too. Not a big deal, and I am sure I can just re-use them without an issue, but it got me thinking... A few vendors sell a "stud eliminator kit" which is simply a pan head bolt that screws in from the inside and a nut that goes on the outside. Why don't they just use bolts? Am I missing something? Seems like I could find a bolt the correct thread and length and just screw it in from the OUTSIDE. Inquiring minds want to know!
