Loud clunk in front and throw my alignment off

[BlackScorpion]

OK guys, been dealing with this for a while, on my 2010 H3T, had my whole front end done bushings, ball joints and one new camber bolt installed. Had my alignment done after the work and a week later heard a loud clunk and my alignment went off and truck pulls to the right. Took it back to my mechanic and he claims the alignment place didn't tighten the bolt and it came loose. Ok , took his word, few day later pulled into my driveway and heard the noise again, truck pulls to the right? called the alignment place and they re-did the alignment. On my way home , i heard the clunk again and truck starts pulling to the right, took it to my mechanic and he claims they can't find anything causing it. Has anyone else ever had this issue? I'm currently have the truck sitting as i'm scared to drive it and have something come off. Can you guys provide some suggestions of what could be causing it , I highly doubt i'm going back to this mechanic shop.

Any help would be greatly appreciated.

I'd look first at lower control arm bushings to see if they are worn. The lower control arm could be shifting. Its not uncommon for the bushing to be worn, apply the brakes when driving and the truck pulls because the LCA shifted. Heck, I'd also double check the upper control arm bushings too.

Check the steering rack for cracks. It can break and separate causing the alignment to change. Look closely where the black-painted steel tube meets the alum. casting.

Invest in a GoPro or Akaso EK7000 (cheaper and same video quality) and take a video underneath while driving. You'll find the culprit.

If the steering rack bushings are shot the rack can also shift and will do exactly what you described.

Make sure to verify that the front hubs are in good shape. I had one recently that by all accounts when checked, tested seemed just fine but when stepping on the brakes would shift out of straight and cause a loud clunk. Was very weird. No other tell tale signs.

This is an issue that I have been trying to track down with my T as well.... I get the clunk and over time my alignment gets thrown off, but it sounds like yours is much worse then mine

The cam is a good idea. I would also put locating marks on each suspension piece. Drive it, when you hear the clunk, check all your marks. You should know right where it is then.

UPDATE: Took the truck to a different shop, explained the situation to the mechanic and we did a test drive, just what i told him happened. He stated let me get up on the lift and see if i can see what's causing it. half hour later, i get some news. Apparently, when the last shop did the front end the did not tighten the upper control arms and they bounced back and forth, he tightened them and did an alignment, after taking it on a test drive for what seemed like a 1/2, he came back and reported that the truck is running right now. So I hope this was the problem. It only cost me $60 for the alignment, so i can't complain. Only time will tell. so far it seems to ride tighter, and i made further then the last time with the alignment at the other shop.
