OK, Bought a 07 with a couple problems today.

I think what happened is. I was driving down the trail and hit a hole in the road that was hidden by weeds and naturally the strut pushed the wheel down to full extension before hitting the ground again.
Because the RC upper control arm did not hit the bump stop i think the spring pressure slamming down damaged the threads.
It took about 5 minutes before i could tell anything was wrong but by then it was too late anyway.
I don't know if it's normal or not but with the RC upper control arm it lets the suspension hang down about an inch below the strut then comes in contact with the bump stop when the lower strut is unbolted.
I think i need to get new upper control arms. I think the suspension should hit the bump stop before the strut bottoms out.

Continuing with my replacement engine i finally have the cam back in it and a new Melling timing chain, cam phaser, GM actuator bolt and Dorman tensioner.
I thought about doing a VVT delete but decided against it. For one, I'm not out for all out performance and the VVT is not a bad thing for my situation. 99% of the time just normal everyday driving.
My stock cam is fine and with new cam bearings i should not have any problems for a long time + saving the cost of a new cam and a tune saves around 1K.
I will be getting a BB tune after i install this engine. BB is only about 40 miles from me.
