Steering wheel shake at high speed after strut replacement (Pls move to 7th gen forum
2004 3.4 Impala base - I replaced both front struts a couple days ago, and torqued/tightened to spec (both off and on ground to be sure).
Everything seemed fine on the street for a couple days, then I took it on the highway today for the first time. After being on the highway for about 5 minutes, my steering wheel started vibrating/shimmying/shaking terribly at about 60 mph. It was slightly noticeable then abruptly got worse.
This was not the type of shaking you get with an out of round tire or a slightly bent rim - this was more like a violent my-wheel-might-fall-off kind of shake.
I turned the hazards on and rode the shoulder to the nearest exit. I feel no shaking/vibration at lower/street speeds (0-50 mph). Luckily I was able to coast it along and avoid a tow.
It's back home now - I jacked it up to see if there was some looseness/wiggle in the wheels, passenger side has an ever so slight wiggle, but generally not feeling a whole lot of play in the wheels - the lower ball joints/control arm bushing aren't in that great of shape, guessing they need replaced but want to make sure I know exactly what is causing the vibration - My question is:
Would the ball joints be the most likely cause of the vibration, or is it an issue with the alignment after putting on the new struts? I've done a strut/spring assembly, never had this problem. I did use aftermarket/cheap Monroe stuff, maybe that's the reason but there's not a whole lot to the strut. There are new CV axles, tie rod ends, and wheel bearings on both sides as well, those were replaced a couple of months ago. I've basically had to replace my whole front suspension with the exception of the ball joints which are still original (166K).
