Knocking upon acceleration
What's up everyone?
I have a knocking sound coming from the rear of my truck and I took it to a mechanic who could not find the source. The truck has a 4" Fabtech suspension lift and is a 2 wheel drive. Could this be "Shock Knock". It only happens when I accelerate from a complete stop, or when stopping relatively abruptly. I have also hear that it could be the sway bar. Motor mounts are good and u joints and lugs are tight. Any ideas?
Look forward to hearing from the community!

Did u check any of the shock bushings? Even though they may be some what new, it has been known for them to crack sometimes especially when the truck is really tourqed out alot. Also how bout getting in the back have someone accelerate and stop, and put your ear to the bed and try to narrow it down to one side..
