I am trying to diagnose an issue that occurs when I either: turn aggressively into a driveway, onto a downhill on-ramp, as I am finishing a turn onto a flat street coming from an steep uphill road, making an even moderately tight, up to a full crank U-turn and sometimes immediately over speed bumps with a slight turn after.
The Issue is a scraping sound coming from somewhere in proximity to the front tires/axle accompanied by the forced slowing down of my truck and sometimes a slight dip in the front as if it was compressing.
I was thinking it had to be tire rub, however there is no obvious signs of rubbing in any of the areas that potentially would come into contact with my tires. We have trimmed/cut/pounded everything, even the frame as much as possible before entering the cab compartment. I am considering either replacing the CV, wheel bearings, more cutting and welding, or going down to a 285/75/17, however I am trying to avoid loosing any height, I like how the truck sits currently.
From what I've read, It seems like there should not be any issues running this setup on my truck, and my buddy who has been helping me has worked on a ton of F-150's with a similar setup with no reports of rubbing issues.
Is it possible that it could be my CV Joint or Wheel bearings? Would That create these same effects I noted? Wheel turned about 2 rotations to the right
Maybe jackup the front end under the axles and then have someone turn the wheels back and forth while you’re looking for anything that doesn’t look right.
well, if you crank the wheels two turns and get the noise. I would TEST again, same road, same speed at 1.75 turns of the wheel, then 1.50 turns of the wheel and see when the noise starts.... If it was the CV or bearings you would think you would still get the noise at a slightly reduced turn angle... If the tires are hitting and you back off 1/2 rev and it stops, that should narrow it down..
How much LIFT ? There have been comments about putting the CV joint in a bind if you get too much of a LIFT KIT... Excess lift and hard CRANKING could be binding inside the CV ?
