Cant take the shake
 

So the other day i got my blazer on the road. It had been sitting for over a year and now when i drive it over 60 Mph it shakes seems to be from the right front i changed the front tires to the rear and it helped some but still a vigorous shake at 70mph the ball joints seem tight and wheel bearing makes no noise or has any play that i can tell i think it may be the idler arm ? I think im lost on the subject and cant live with a shake

can anyone plz help me with this im stumped and i have no clue and am on limited amount of time

What are ya driving?
Does the shake appear at low speeds and then gradually increase in annoyance or just all of a sudden at speed?

its a 1995 chevy blazer it slowly gets worse after 70 and up till its horrible

Where did it sit? pavement? Dirt? Did the tires go flat during the idle time? The tires "could" be the culprit.

Could be a pitman or carrier arm. What you might try is taking it to a decent alignment shop and get a quote for an alignment. Good shops will tell you they won't align a vehicle with bad tie-rod ends, carrier/idler or pitman arm failure and/or bad ball joints. At least in my experience. At least you could get an analysis.

So heres what ive accomplished i replaced the upper and lower baljoints and the idler arm. Blazer still shakes and i have no idea why the garage told me it was gonna be the ball joints all tie rods seem tight and i have regreased them to make myself feel better so now im in NC with no clue as to why it shakes its perfect under 70 so any other ideas ???

Odds are the tires have developed a flat spot in them from sitting for so long. Or possibly a bent wheel. I'm leaning more towards lumpy tires though
