I'm getting a popping sound out of the front passenger side strut when I go over bumps and whatnot. The strut cap doesn't seem to be flush with the strut like the driver side one is. Any idea what the problem is?

 

go take it to a shop or a dealership and ask them to take a look at it before it gets and worse

 

the bolt on your strut is probably loose... kinda same thing happened to me.. I switched to the TRD struts and a month later the bolt loosened up... I took it back to the dealer who installed it and all they did was tighten it...

 

have you done any after market suspension work?

 

I went in there and tightened the bolts up and it fixed the problem. Such a simple fix...
