Ok so I have a 00' xj with just a 3 inch lift and 31s, while making a left turn ill hear and feel a popping/banging noise on the floor boards. Also does this while I accelerate from a complete stop but it eventually stops. Anyone have any ideas?! Its driving me nuts

1. Exhaust mount
2. Engine and/or transmission mount

Here's a photo.

For the popping noise, go ahead and tighten the track bar BRACKET to frame rail bolts.

I replaced the ball joints, hubs, u joints, lower control arms, upgraded the tie rod, tie rod ends, track bar, steering stabilizer and sway bar links and bushing. And it is still making this banging knocking noise. I am able to twist the u joint back and forth on the front drive shaft. Not sure if that is normal or not. Still can't figure it out

Your response to me says you did a bunch of stuff but not what I suggested...........

Yes, I've experienced this myself.

Doesn't take much to make them pop, looks secure but not.

Exactly!!!

I could elaborate on this and how we discovered this at the dealership, but since nobody's paying attention, I won't bother.

Throw more parts at it!!!!

Those parts had to be replaced anyway but I'll go ahead and try it. Thanks

I'm experiencing a popping when turning left also. I tracked it down to the right axle mounted upper control arm bushing. The bracket got tweaked enough to unseat the bushing and now I get noise. Some Johnny joints are on my list to fix it.

I'm having this same issue on my 01, did this solution work for you? Only when I turn left, nothing turning right.
