Jeep Repair: steering/suspension repairs, axle/wheel bearing service, vehicles road travel, jeep wrangler yj, crooked down the road

Question
MY 1993 JEEP WRANGLER(YJ) DOES NOT DRIVE STRAIGHT DURING ROAD TRAVEL. I WAS TOLD THAT WHEN TRAVELING BEHIND MY JEEP, IT'S DRIVING SLANTED AT A LEFT ANGLE. WHAT ARE ANY POSSIBLE CAUSES/REASONS THAT THIS MIGHT BE HAPPENING?

WHAT DOES THE TERM 'DOGGING OUT' REFER TO? AND IF HAPPENING, POSSIBLE SOLUTIONS?  

Answer
I am not familiar with the term dogging out.  I am familiar with vehicles that "dog track".  This refers to the front and the real axles being out of alignment with each other.
The telltale sign is usually the Jeep looks like it is driving crooked down the road.   An alignment shop can tell for sure.
Your leaf springs are probably getting weak and since most of the weight is on the left side of the Jeep, that is where worn springs will show signs first.  New springs are the only cure.
