Cracking / Popping sound

Symptoms...

A series of cracking/popping sounds is heard from the front end of the Rx8 while pulling in and especially backing out of parking spots (with the wheel cranked).  It also does it while coming to a stop with light brake pressure (wheel straight).

I thought it sounded like a loose wheel.  Torqued and tightened everything a few times. I also went over every bolt I could find in the front end of the car and didn't find anything loose.  I also tried to pry on the hubs with a pry bar to see if I could figure it out - but that failed as well.  No obvious wear pattern spotted on the tires either.

Im out of ideas.  Bad suspension bushing?  A scary thought is a ball joint is about to blow out... Dunno

Checking the ball joints involves getting the front wheels off the ground (safely) and shake them up and down and back and forth hard. have a buddy watch where the issue is if you feel play.

Let's see...

- Doesn't make noises in corners like a wheel bearing
- don't have brake disc covers
- sway bars and links seem fine and the bars shouldn't be loaded when I have issues
- ball joints don't budge when I had the car jacked up

I'm perplexed  :huh:

Do you have aftermarket bushings?

Nope... 2 more data points though

The dealer couldn't find it either. Gave it back to me after inspection and said "it can't be anything major" and then bitched that I have too many aftermarket parts to be sure...

Also, I drove. Through a monsoon rain storm and it stopped the sound until it dried out.

Might be.

Don't know, maybe I will start squirting things up until it stops
