Crown SC4000:
Reduced traction above free lift

Hey all,
I am working on a SC4040-40 that is experiencing a significantly reduced traction issue above free lift only while turning to the left (forks first) or to the right (power unit first) Long story short, traction motors have been swapped and no change, the accel pot, and steer pot have been changed, distribution board has been swapped with a known good lift, MRC1 and MRC2 have been replaced, swapped side to side and also have swapped in known good controllers. All of my inputs into the DB to the MRC1 and MRC2 are reading normal. The power cables to the right side motor have been replaced as well. Concern is still present. Am I missing something or what because I have bee chasing this issue for months now. Any help will be greatly appreciated! Thanks
