I pulled my rear hubs of and replaced the bearing and installed toe eliminator sense i had it off, but know i cant get the bottom part to go back in because of the metal bushing keeps moving. what should i do i cant figure this part out.

 

Press the metal bushing so its sticks all the way out giving you the maximum opening. As in, make the bushing flush with the inside of the hub. Then when you torque down the bolts it will slide the bushing back into place. I believe you can use a socket and a vise.

 

.with the spindle assembly Off the car.
Stick a nut and bolt through the Hole That doesn't have the steel Bushing( or sleeve) in it.
Put the bolt through and attach the nut.allow Extra thread so the NUT sits on the Sleeve and the Bolt's threads goes a BIT through the Sleeve.
Hit the Bolt with a Hammer and it will drive the Sleeve In and make it FLUSH so that you can now put the Assembly back on.
i hope that is understandable.
