I recently replaced my crappy Megan coilovers for some stock struts with Swift springs. When I went to go get it aligned at Firestone, they said my front/passenger side hub was damage. Like while it's in the air, you can jiggle it up and down. He told me that when I hit bumps, the car can shift sideways, which I was feeling while driving to Firestone. It wasn't like this before though a few months before and I never really felt the car shift sideways with the coils. Is it possible for the coilovers to break my hub?

 

The hub is bolted to the strut by two large bolts at the top. At the bottom is the ball joint. So, at which of those two locations is it moving?

 

^^^ second that...check to make sure not broken

 

....

The hub is bolted to the knuckle and the knuckle is bolted to the strut.

You probably have a worn wheel bearing/wheel hub if there is excess play. A coil over will never damage a knuckle.

 

coilovers and wider rims/tires/bigger offsets ruin wheel bearing and thats what it sounds like is your problem, iam going through same thing right now just had to replace my front wheel bearings for the 2nd time cause of i have 17x9.5 and coilovers
