i have a 2000 blazer and when im on the highway and hit a bump in the road or a joint my truck starts bounceing all over the place. it feels like someone is rocking my truck side to side. i put brand new shocks on it thinking that would stop it. but no luck. any idea this thing sucks driveing down the highway lol. it has 104k on it also
