Hey guys I have a weird problem. I have 275 tires in the back. Quadshock is still on. Clears it by alittle less then an inch. For a year now ive had these wheels and tires on there, it never touched the quadshock. Went on vacation for a week. Came back yesterday drove the car and when i turned left while going like 50mph on a long curve, the wheel was jerking right by itself, I noticed it was weird, thought maybe its time for an alighnment. Now today I drive around alot maybe 20 miles to best buy, on my way home, I leave parking lot pretty fast, and i notice a squeaking noise, and a strong burnt smell. I come up to a light everything seems fine, so i decide to have fun give it a nice launch, and the car DIPS HARD to the back right, and the whole car jerks sidewyas alittle, something the car usually does when its launched hard, loses traction and goes sideways but I notice the dips was very hard. And usually in 1st-2nd gear now I hear the squeaking. Then I come up to another light, I leave in first like I would any other time, slow and easy and the car dips HARD again and the front lifted up pretty hard, I realised something has to be wrong with my suspension, so I drive very slowly home, everything works fine, drives perfect except that noise and the occational pull to the right and the strong smell of burning rubber.

So I get home, look under my car check the lower control arm, axle, everything lookse fine and strong dosent move. I look at the quadshock, and the outside part has melted rubber to it, and my tire is sticky and melted on the inside. Obviously the tire was rubbing against the quadshock. I tried moving eerything see if it would budge just alittle, but nothing moved everything seems strong, and still had the less then an inch of clearance. So whats wrong? how can it be that after a year of driving on these tires pefrect it all of a sudden starts to rub on the quadshock? Is something bent? I didnt hit the car no hard bumps, nothing. The torque boxes looked fine but i couldnt see much with the wheel on. Im going to take the wheel off and take off the quadshock tomorrow, see if i can find anything, and its ONLY the back passenger side wheel, driver side is perfect stil.. Any guesses please?

Are you still running the stock arms/bushing?
 
Mob,

I would go through and try to tighten up all of the bolts and nuts just to make sure that nothing is loosening up. Failing that maybe the bushings on the control arms are starting to go and they have some play in them. Others will probably have more suggestions but those come to mind off the top of my head.
 
hmm alright thanks guys. Though im pretty sure if I go down there those bolts are so old i doubt ill be able to tighten them or loosen them. How can I check if the bushings are bad, by apperance? I dont have a torque wrench. Im broke till wednesday but if the bushings are bad should I use this as an excuse to upgrade lca's? :)

oh and should I take the quadshock off? I really want to before it burns the tire off to the rim, my tires are already bald, I dont need anything else making them worse.

You may get wheel hop from removing the quads. But, it will stop the rubbing issue.
If low on money, get some poly bushing for the sock arms. Then while you have them out get torque box reinforcements installed and the lowers boxed. Will be cheap if you can do it your self. If not, it will be cheaper to get some good LCA's to install but, you will still need to install torque box reinforcements.

yea, I think im just going to take off the quadshocks untill this wednesday and ill order some good lca's. Ill deal with the wheel hop till then. My tires cant take any more abuse, heres how bald they are, im going to need new tires next.

Looks like you need to lower the pressure in those bad boys. I see alot more wear on the inner tire then on the outer edges. I run my Micky DR's at 16-18psi all the time. Of course it's only a good weather car!

hmm ill try that, I have them at about 33psi, i think the max is like 45 or something, ill put them at like 28. I noticed my gas mileage went up though when i put the psi up.

You'll like them at 22-24psi best but, you will deffinately have to remove the quads because the side walls will buldge.
 
Be sure you're actually trying to turn the correct bolt.

There's something there that looks like a bolt, but it's actually welded to the frame. I broke a wrench trying to turn it (using a bottle jack), and then realized my mistake.

I did remove my quad shocks.

I think with 275's you have to have them turned or the tire wont fit. I had to with just my 255's.:shrug:

Ive been using my 275's for a year now, and a bigger slick on the rear, and it fits perfect, like i said theres alittle less then an inch of clearance, and the driver side still dosent give me any problems. Something is wrong.
 
had this same problem. Put new control arms on with poly bushings, PROBLEM SOLVED! And to comment on tugging and pushing on the control arms and the car to see if they move...... Your car weighs over 3,000lbs static, your putting maybe 200lbs (benefit of the doubt) to see if the bushings are giving or not.

I'm sure you get the idea... :)

arent there 2 bolts towards the rear and one on the front?

Which one isnt a bolt?
Lower pivot point has the bolt you turn facing the inside of the car(towards the center). Top mount is just a nut that goes on the frame welded stud.
Besure to use a lot of 3 in 1 oil before you start wrenching.
