I need advice with my suspension!

I recently purchased a 2008 4 door Wrangler X. It has a 4" Pro comp lift with 35" tires. Just yesterday as I was driving I had a deathwobble after hitting a bump. I have noticed a grinding/crunching noise when going over railroad tracks and bumps. I got under it and I think my Jeep has the stock control arms. I thought these would be changed with the lift kit. Anyway, the control arms seem to have a little play around the bearing when I jerk on them. More in the driver lower control arm then the others. Also my tires are getting a little worn and probably don't have another 10K miles before I'll need to change them. They have been recently balanced. I had the death wobble in my 2 door TJ and it was temporarily fixed with a new steering stabilizer.

I have a few questions though. Do I need to change the control arms with a different length? Should I just change the bearings? If so how hard is it? Could it be something else? I just need some advice!!! I'd appreciate it. Thank you!

Assuming that you bought it with the lift and tires already installed, I would say you will be better off having the entire front end looked at. There could be any number of suspension components that are simply worn out. Any one of them could cause DW but more often than not, it is from a combination of worn parts.

Going to be difficult to diagnose online since there is no real way to determine how long the Jeep has had the current suspension/tire setup or how it was used in the past.
