Ok, this is for anyone that knows answer, my lower steering shaft at box is going bad due too body lift I'm told. my steering has a good bit of play in it. I was told by a mech at work to call summit and get an after market with dual u joint, they at summit said I gotta give info on shaft, like if its spline shaft how many splines...at bottom of collar, that's what I'm calling it I can feel a bolt..a 13 I think..im guessing I simply take bolt out or loosen it and bottom of shaft will come off. I of course took top end apart to do body lift but haven't done anything else. any help or advice would be appreciated
