New member, '97 tacoma w/ handling problems

Hey everybody, just sold my 1980 Hi-lux 4x4 and bought a '97 tacoma reg. cab 4x4 cause I wanted a nicer hunting truck. Already miss the old one, had character. The '97 has handling problems, when I go over a rough spot, dip, bump, or pass a semi on the interstate, the rear-end of the truck has a side to side motion, like it wants to fish-tail. Has anybody had this problem with theirs? Can't see any noticeable problems. Read these models had problems with broke leaf springs, they dont look broke, dont think bad shocks would cause this problem either, any ideas would be greatly appreciated, thanks.

 

welcome! and idk i have a 97 with no problems like that. my trust is a BEAST
