Ball joint?

I have been getting a clunk under the driver side floor board when turning, primarily when turning slow. Axle u joints are new. Tie rod and all pretty new. I assume it's ball the joint.

How likely can I see movement when it's jacked up and I use a pry bar between the knuckle and gusset?

Re: Ball joint?

the track bar is connected to the frame rail in the engine bay. and when it goes bad it will clunk when you turn. the rail runs about center down the floor on the drivers side. its pretty easy to check with some help. just have someone slowly turn the wheel and watch the track bar for movement left and right.

Yeah between the knuckle and axle C. The lower is a real ball joint and there shouldn't be any movement there. The upper is spring loaded pin that goes up and down to absorb shocks while driving and slop in the lower. Don't use cheap Auto Zone type parts as they are over sized and will enlarge the bores in the axle C. If you find any slop probably do all 4. I'd go with Spicer kits. They cost about $125 for all 4 and last a long time.

Don't know about your Autozone but the ones around me, all their ball joints are re branded Moog.
I think whats causing the enlarged bore in the C's is driving the ball joint sideways because they don't want to use the correct tool adapter.

When I was dealing with this problem on a Jeep that was dropped off for some work, I got every ball joint NAPA sold and none were as large as the one that came out. Spicers would just spin. And the old ball joint wasn't splined either. I have used MOOG ball joints in the past and replaced them with Spicers and never had a problem.

Re: Ball joint?

Moog has a problem solver line of ball joints that have a slightly over size housing.
Sound like the parts monkey sold the wrong part. Should have been noticeable on installation

Spicer 706944X. One kit per side, so buy 2 to get all 4.

Even if the bar itself is good, the hole where it mounts to on the frame bracket can wallow out and allow the bolt to move around in the hole, causing that sort of pop as well - it's happened to me a couple times.
