rear tire wobbles

[JDM240SXcoupe]

So i took my car for an alignment and the guy couldnt align the rear because the rear pass side tires wobbles. I knew it did just didnt know it was gonna be a problem for the alignment. So he said it could be the spindle. My question is how do i fix it? Whats the spindle? i searched but coundt really find much. What parts do i need, thanks for the help.

Here's an exploded view of your rear suspension from the axle. The spindle is the second item from left to right. The wheel could be bent itself. Could also be the hub (part with the lugs that your wheel bolts onto)

Its wheel is not vent because i replaced it with another one with didnt wobble and still does it. Hub could also cause this?

The hub rotates with the wheel in the wheel bearing so if it is bent it would wobble.

Well the rear doesn't have a spindle. It has a splined axle shaft which slides into the rear hub and gets bolted in. The rear hub is bolted to an iron upright. I would very much doubt that the issue lies within this. However I would remove this wheel and jack the rear of the car up, and pt it in reverse VERY CAREFULLY. And use a solid surface (like a milk crate) and a flat ruler can bring it in to the very edge of the brake rotor and look for visible wobble. Then put a known good set of wheels on the back and see how it feel. Make sure all the suspension arms are torqued and show no bends first though.

I would think the wheel is bent, rotor is warped, or the tire is out of balance, before thinking its a hub... unless your axle is broken.

^^^^ True true. If its not the rotating assymbely then it has to be the wheel/tire. By the way OutToWinPAHC, your powdered wheels and dif cover look amazing. Way to keep those wheels fresh.
