Check the anchor plate bracket bolts. Very common in these trucks. They loosen and cause a clunk when you hit the right bump. It usually gets worse with time. Let it go too long and you could eventually loose a wheel. It won't fall off usually, but it could damage the wheel beyond repair. Most folks usually find the problem before that happens and it also depends upon which bolt becomes loose and falls out.

It's also one of those parts you can look direct at and not notice any problems lol. So check anchor plate bolt torque, it also has nothing to do with alignment.

BTW- since your alignment is out, is the steering wheel strait? Do you have aftermarket adjustable cams for camber/caster? Realize, your going to get more vibration transfer with the front end so tight, -I'd check the passenger side plate bolts first.

I could go on but I'm winded. River1, do you ever get winded lol

Listen to these guys OP, good replies for sure.

Anchor plate bracket bolt - dont believe I've heard of that before ...where exactly are those at? Thanks for the advice. The clunking is gone since I changed the idler arm. But certainly want to check those bolts out.

Since truck was aligned I have no vibration and she drives down the road straight. The clunking and feeling was just when I had the front end up higher or lower going up or down a parking gargage.

Well guess what, turns out it was the starter in the on or engaged position at all times!! To me it didn't sound like the starter but that's what it was evidently! Thanks everyone for all the ideas. I just wanted to let you all know that's the actual situation has.

Wow that is definitely a new one.

Damn, how could a starter survive like that ? But yea, that can happen. The GEM could cause it or the ignition switch on the column could go bad.
