Post subject:  Suspension Noise (Clunk)
I have a '05 Jeep Liberty CRD.

I just replaced all bushings, ball joints, outer tie rod, springs and shocks with Moog and Monroe parts on the front suspension.

Inner tie rods replaced 5K miles ago.

I am getting a clunk when I go in reverse from a hard left and also when I turn the steering wheel hard left with the car stationary.
The clunk seems to happen "forward" once and to the "rear" once as a cycle forward and reverse. It does not happen repeatedly as the wheel turns.
I do not feel it in the steering wheel.
Sounds like it is coming from the front left of the vehicle.

I pulled the front wheels and rechecked my torques and everything is at torque with no movement of nuts. I used castle nuts and cotter pins on the lower ball joints and outer tie rods.
The front axles CV boots appear in good shape. The front bearings spun freely when I had them off the car.

Have you checked the mounting bushings for the Rack & Pinion assembly? They do wear out and let the rack become loose with some unwanted movement.

I have not looked at those bushings. How hard is the job?

See the link I put in my post.

Has anyone had a CV joint clunk once around NOT clunk every rotation of the wheel?

That steering bushing seems like a remarkable job... she wasn't an issue before the suspension work. It has to be something I touched.

So I get a single clunk going forward hard left and get the clunk going back with no change in steering wheel position.

I can make it clunk back and forth pretty easily. I have been watching the suspension components to no avail.

Are you SURE it is coming from the front?

Well... she never made the noise before the work and I didnt touch the rear yet.

U joints and a front drive shaft cv joint was replaced a year ago.

Does the noise happen repeatedly if you transition from forward to reverse repeatedly with the brake on? If so, that sounds like an engine mount to me. Not sure why it would pop when steering, but it would be worth looking into. I've also had (and currently have) front CV axles that pop when turning the wheel. The bearings inside seem to bind and release as they pivot past some arbitrary point in their motion. This became more of a problem for me after getting my lift, but even replacing bushings and changing the stance of the vehicle slightly could, potentially, have a similar effect.

You could have someone sit in the vehicle and steer back and forth on smooth pavement while you lay underneath and feel for where the pop is originating. Just be sure to have the vehicle in park with the e-brake on!

Had a similar noise but from the RH front.
Turned out it was from the upper control arm(UCA), rear mounting bolt was loose allowing the UCA to shift slightly. Tightened it up and noise is gone.

Which side was loose on the UCA?

Check for proper torque on your control arm bolts. Had the same issue in my 08 grand cherokee
