Finally driving my 76 fj40 after 4 years of rebuilding. I've found cornering a little unpredictable. Usually on broader sweeping corners, anywhere from 20 to 35 mph, I start into the corner in a consistent arc. Right after the rig rolls into the bank, I'll get a second 'pitch' where it feels unstable and 'finds a new line'.
This obviously makes me really lose trust for higher speed corners, like freeway driving.
Current state of my cruiser is, 2 inch lift by OME with new leaf springs, shocks and shackles. I added 4 or 6 degree casters (cant remember which). It tracks very straight, maybe even a little heavy. I havent aligned for toe.
My current philosophy is that my shackles are pivoting throwing my axel into a different arc after the turn starts. The reason I'm thinking this, is I installed rock lights right on the rear shackle perch. The drivers side shackle was nearly vertical while the passenger side was leaned way back. I jack up the back on the frame, which straightened the passenger side.
Any other ideas on what could be causing this? It my therory is true, do the shackles need to be tightened?
