I just installed a set of 2.5" spacers on the rear of my 1999 blazer. The same day I also replaced the rear shackles with 2" lift shackles. I noticed that my driver side tire/wheel sticks out about an inch or so more than the passenger side. The frame is straight. I'm not sure what could cause this. Any thoughts? Could the rear stabilizer cause this by possibly pushing out the axle to one side?

 

I doubt the axle is sticking out any extra... If it was, the c clip in the diff would have to somehow have broken or come off, and the axle would slide right out!

I would check your spacers, maybe they weren't the same?

 

Sorry, I didn't mean the axle shafts but the entire rear end being offset to one side. The spacers are a matching 2.5".
