I have developed this weird front-end CLUNK that I'm having trouble diagnosing.
The noise occurs when the steering wheel is turned at least partially, and I move slowly over a bump, like a speed bump or rain gutter while turning, either steering wheel fixed on one position or in the process of moving. Most of the time, there will be some small "crack" noises here and there with one loud clunk/pop noise. It happens ONLY when going slowly AND turning. It will not do it when cycling the suspension while stationary, and it doesn't do it when going fast or straight. The sound appears to be coming from the driver side only.
I have checked the ball joints, and they appear to be perfect, no play, and good boots. The steering is nice and tight, and the linkages seem to be in good condition with no play, etc. No clicks when turning on flat, level ground w/ the AWD engaged. The top nut on the strut is good and tight, and the bushings on the top and bottom of the top plate appear to be in good shaope. Weird...
Anyway, I'm thinking that it's a CV axle/joint, and here's why. When turning, the CV joint is in a different position than for straight, normal driving. Combine that with a cycle of the suspension (upwards) and the CV joints on the driver side have to compress to take up the additional length as the wheel hub gets closer to the same elevation as the output of the differential.
I'm pretty sure that this is my issue, but I just want to check here to make sure. I have some Poly steering rack bushings (first thing I checked) ready to install since mine allow the rack to move almost an inch on flat ground. I'm also ready to replace the front shocks (148k on them) since the lower eye bushings are very weak even though the shocks still feel fine. I'm thinking of getting an Auto Zone CV Axle for $70 and swapping that while I'm already doing the other work.
Has anyone else had a similar noise, and if so, what was the cause?
