vibration
Hey guys .. new to this forum hope maybe one of ya has experienced my issue ?
1971 suburban with a bit of front end / maybe even total shake at speed. I do have a bit of freeplay in the power steering to the right, the alignment is set all new ball joints and inner outer tie rods, sway bar bushings and shocks. I have not re balanced the wheels yet. Also note that when I hit a bump straight on the front feels like it shakes side to side my next attack is the control arms lol. thanks in advance for any ideas you may have Dave |

Re: vibration
A funky tire or unbalanced tire can have a huge impact there.

Re: vibration
A bad shock will do it also.

Re: vibration
Ya I'll balance the tires tomorrow before I leave work tomorrow panhandler62
I already replaced the shocks last week Pgsigns, I think maybe the play in the steering isnt helping even tho it showed corrrect toe when i aligned it maybe I really have the wheels turned a bit when I hit a bump causing the front to shake side to side almost feels as the wheel folds over but the tire pressure is correct. I appreciate both your response's have a great week ahead |

Re: vibration
Well at least you found your issue Zellway glad that fixed it .. mine already has the one with the polly bushing what I have noticed since balancing the wheels is now the shake only happens in the front when I hit any size bump causing the front to shake side to side annoying as all hell. Next thing for me is to swap out the a-arm bushings all the ball joints and tie rods are done

Re: vibration
Nice looking setup. Post up how much caster they are able to get on the alignment. Be nice to get 4 or 5 degrees in it.
