help please!!!!

[Tmend]

Okay so im almost done with my frame when i ran into a ploblem. when my front bags are inflated they reach 100psi and the upper part of the spindle hits the upper control arm and prevents it from turning or going any higher. i ran into this problem once i bought the suicide doors bag mounts with the cups. i think the cups added extra hight causing thr contact. i dont want to remove them becuase with the bags fully deflated front and rear the truck sits level. any thoughts or help.

let me add i double checked but is it possible my spindals are installed on the wrong sides the are cpp drop spindles

If your calipers are toward the front then they are on the wrong sides. The calipers are supposed to be to the rear side of the spindles. WES

i double and triple checked they are on right.. the one with r is on the pass side and the one with l is on the drivers side...no one has had this issue?

wrong ball joints!!! what year ball joint did you use...I'm pretty sure you used the early one....try an 87 ball joint.... the taper is different

[Tmend]

the spindle is for 73-87 frucks and i used ball joints for a 1973..so if the taper is diff will this not allowe the ball joint to slide all the way in the spindle giving me a bigger gap between the control arm and spindle?

[Tmend]

remember this is only when the bags are inflated. fully deflated or half way i have no issue....

Correct..I would check that first

[Hottrucks]

not sure what look your going for but I would take 1" off those lower cups to...you'll be much happier

and your missing the bumper in the upper A arm

the only thing i like about the cup size is fully lowerd the fruck sits level. if i remove i inch off then the front it will sit one inch lower right?

yes but with air it doesn't matter what is important is that yor bags are somewhere in the middle when at ride height

Jeff

by the way it look good so far

[Tmend]

you got a good point so what i wil do first is cut 1 inch off the bags. then recheck if at 140psi when inflated the arm does not rub. i was running flat plates at the bottom and did not have this issue. the 1 inch removale will help and i can keep the same ball joints...i have read alot that the cups from suicide door are on the larger side and people do cut them.

[Hottrucks]

yea but if the ball joints are wrong then there wrong...also you must be new to air I run about 65 psi at most in my front bags with a 500 caddy motor

[Tmend]

yea sorry when i said 140 i ment at the highest preasure on full lift. i havent got to drive it yet LOL. so at ride hight while driving what sould i run the front and rear bags at?..the ball joints work well when level or deflated the swivel fine no binding or grinding. the spindle did not bottom out it only went up to were the ball joints starts to look like a ball. (tapper got larger) same ball joints when i had the plates on...and yes this is my first air ride set up as you can tell...AND THANKS FOR ALL THE HELP THIS IS WHY I LOVE THIS SITE.

[Tmend]

I where i got the ball joints and they said from 73-87 the ball joints are the same part # ?

[Hottrucks]

I beleive they are but be sure if the taper is wrong it will be dangeriuos and will ruin your spindles

[Tmend]

How do I know if I have the wrong or right ball joints. I can't compare I already trashed the old ones.. I really don't want to keep buying and returning parts.. However I wantvto get rid of this problem

I'm wondering if just putting the bumpers in would solve it??? would limit the travel and may be enough...

[Tmend]

Thats what hottrucks said. I'll order some and put them in. I measured and there is about 1 1/2 each between the upper arm and the crossmember when inflated. I don't think the bumpstops are the big not sure tho

this is what i got went to 4 diff auto supply stores all ball joints are the same..maybe my problem is normal and the suspension was never desiged to go that high.

[Hottrucks]

f you look at your first pic you can see that the nit is tightened to far the cotter pin should be though the nut not below it

[Tmend]

im thinking of just buying cpp upper ball joints since i bought there spindles...

not to dog CPP because I get in trouble for it....but just fot giggles try the 67/70 ball joint...from the drum brakes....it has to be one or the other and since those don't fit...I would go with the other..OR ask for JEFF @ CPP he has done wonders for other board memebers... do not deal with other people there then ask him which ball joints....I would try the other ball joints first

[Tmend]

this is such a dumb problem to have. you would think since i bought 73-87 2 1/2 drop spindles a 73-87 ball joint would fit.. man this sucks
