I replaced the radius arm bushings, the center pivot pin bushings, driver side ball joints and outer tie rods on both sides. now I have some positive camber going on. why and how do I fix? any help would be great thank u

 

On mine the front end shop showed an adjustable cam like they installed. Said they just kept playing with it until the caster and camber are right.

 

I should have included this sorry, but I took it to an alignment shop and they they did not have enough adjustment in the cam to fix and they just adjusted toe that day, I think I will find a new place to go.

 

This may sound rather basic. But!
Is there a possibility the radius bushings didn't seat in properly causing a shift in the axle ?
There is a better than average chance the rear radius frame bracket(s) are cracked and letting the arms shift.
If you sometimes hear a noticeable clunk when shifting from or to reverse, the arm(s) & bushings are moving in the frame bracket or the frame bracket rivets are letting the brackets move.
Look for wear signs on the frame rails, least likely, or check closely at the bushing seats, most likely.
Mine was the passenger side frame bracket seat letting the arm move.

Now, if you're talking about where the arms connect to the axle bushings, there is a possibility those are made to be installed in a certain position. Meaning that the rubber may be thicker in one area and thinner in the other, causing the axle to rotate either fore or aft.
I personally have experienced them all, however the latter was on the rear axle spring perch. The spacer blocks were tapered approx 1/8" causing the u-joints to lock up. Neither the spring rebuild company or Ford could answer the problem. I just knew that changing the springs wasn't the cause. Lying under the truck and doing some very close scrutinizing gave me the answer.

Good luck

 

Hojolabo, thats very good info! Because I do have that clunk and cant figure where its coming from. I think it may be time for bushings.
My alignment shop owner always has to test drive my Bronco two or three times when they due an alignment. This guy does a good job!
The Ford TTB can baffle the rookie. I found this out the hardway because one time I never saw the mechanic test drive my truck. The owner was at the USC Ohio State game.. The mechanic (the owners son) told me he set everything to specs and that was the best he could do! My Bronco was all over the road!

 

The ONLY caster/camber adjustment on an OEM TTB front end is the cam adjuster between the pins of the upper ball joints and the axle housing. Every other pivot point is a typical pin and bushing setup and the radius arm bushings are bayonet bushings that allow the arms to drop and lift as the suspension travels. The most common issue with the TTB is the inability to overcome NEGATIVE camber before rolling the cam into the caster adjustment. The cam adjusts BOTH settings at the same time and therefore cannot always accomplish the task if there are other worn bushings/components in the system.

You say you replaced "center pivot bushings" I assume you are referring to the axle pivot bushings located at the inboard end of each half of the D44 TTB axle. These are the most frequent culprit when dealing with camber issues. If the truck currently suffers from an excess of positive camber and the alignment pros say its good, I'd give it a couple of weeks and see if things don't settle in and it rides normally.

Radius arm bushings should have no effect on camber. If anything, worn bushings here would cause a positive caster problem when moving forward and negative when backing up.

If you have replaced both the radius arm bushings AND the axle pivot bushings the ONLY components left to cause camber issues would be balljoints.

 

How are your springs and or shocks? they could have an effect on the camber.
One thing I personally wouldn't rule out is that center axle pivot not having an adjustment on it, and I have nothing to base it on factually, just suspicion and I don't care what anybody says. It didn't have this problem when new, why now? I would try the Ford garage(s) and ask ??s and see what they say. I have a 92' 4x4 and had everything changed on the front end except the center bushing and didn't have any camber problem. While at the Ford parts ask to see the center bushing assembly and examine it closely for a cam effect.
As far as one of the other members stating he had his aligned by the mechanics son who said it was all set yet wandered all over the road, that is usually a sign the toe in is not toed in to specs.
As far as the clunk sound in another members Bronco from forward to rev. try the passenger side first, that's where mine was broke. The drivers side was cracked. It's pretty easy if you cut the rivets with a cut off wheel in a high speed grinder.
Good Luck to all and keep us posted with the outcome. We'll all learn that way.
Love this site.

Shocks have no effect on alignment issues and there are no adjustments for the axle pivot bushings.

and possibly a weak coil spring

 

bronco has positve camber when going forward and negative camber when in reverse but radius arm bushings are new and tight. I am going to take it to a different alignment shop in a couple weeks and I will post whatever they tell me.

 

I was reading my Haynes manual "80-96 Bronco" and in section 10-5 is says to mark the camber bushing B-4 removing the upper ball joint. From that I would bet that whomever did the ball joint replacement didn't put any index marks and put the bushing(s) in misaligned. In order to correct it means to remove the upper ball joints and try and figure it out, in your case the buck may be getting passed. JMO with the help from Haynes.
The only thing I thought about the shocks was that if they were weak that the front may sag some and add to the problem. My only reasoning on the center bushing was that I was told that the rear spring plates were equal on both ends by the spring shop as well as a dealer mechanic, upon checking myself up close and personal, I found them to be tapered and thus causing my problem.
I know this has nothing to do with the problem at hand other than sometimes you cannot rely on others entirely. Sometimes there called engineering changes. and the bulletins aren't seen by all. Not so in this case I guess, it was just food for thought.
Good Luck

 

Shocks do not support the vehicle weight. They are for dampening of movement.

 

Sounds like the toe is out of wack. When its toed in the camber will change when going forward and again when in reverse. The oppist will happen when its toed out.
This is why you must have a good alingment mechanic.

You can set the toe your self with a tape measure. Adjust the toe then go for a test drive and check the toe again to fine tune and get it just right. It takes me two or three times to get it just right.

Camber also can change with a heavy load.

 

I'm wondering if the hole where the bolts for the pivot bushings isn't wollered out. I had this problem on my 95. I ended up welding washers to the supports to fix the problem. With them holes wollered out the axles will sit higher and that would cause some positive camber. Thats my 02
