I have a 06 F-150 4x4 5.4l and the tires are at an angle |---/ ---- \ ---| ive changed the upper and lower ball joints I'm thinking the Bearings? if you would give me any ideas of what you think the problem is,i would appreciate it..


plus.... it vibrates from about 59-69 Mph after the tires being balanced

 

have you done an alignment?

 

the alignment is a little outta wack from the rack being changed,i had the tie rods pretty close to aligned when i changed them. would that little offalignment be that kinda problem?

 

sure, anytime you rebuild a worn front end, and moved stuff around the alignment needs to be done.

 

Thanks ill try that out...cross fingers

 

Assuming by upper ball joint, you changed the entire control arm? The bolts that hold the upper control arm are the adjustment points for caster and camber; moving those bolts moves the control arm. If you just threw it back together without any markings before dissassembly, there's your problem.

 

uh yea get and alignment im due for and alignment and my fronts are doing the same thing. / /----\ \ but not bad.

 

thats what i had going on with my truck. i change upper and lower ball joints and the front coil overs and added a level. you just need an alignment. it will start making your tires wear on the inside instead of evenly if you wait to long

 

agreed always make a marking, that way it is pretty close to where it should be atleast

 

this may be a dumb question... does the alignment shop,straighten your caster/camber points on the control arm?

 

Not really sure what you're asking by "straightening", but here goes...

The two bolts that literally connect the upper control arm to the truck have eccentric washers on them. On the frame right there where the bolts go through is a tab of sorts. When you turn the bolt, the eccentric washers turn against that tab and force the control arm in a particular direction to make the appropriate adjustments. Both sides of the control arm have the same washer to offer almost and infinite amount of adjustment to caster and camber, depending on what alignment specs you're (the alignment guy) trying to achieve. In other words, the caster and camber is literally adjusted by moving the entire upper control arm at its attachment point to the frame. Did that help?

 

i had the tie rods pretty close to aligned

 

okay yeah that was it,i just adjusted the control arm and that was it thanks... and i also added some spacers that you twist into the springs that helped the stance out as well...

 

I ran my truck after lowering it for a week before getting it alighned. I could see the wear in just that short of time which was only about 60 miles put on it. This is what I used.
Camber kit from Eibach. I manual straightned it until I could get it in the shop.

 

You should def. get an alignment done. Assuring everything is adjusted to factory spec will help to keep the tires from wearing prematurely. Just because it looks ok doesnt mean everything is where it should be. $50-$60 is not alot to pay for peace of mind.
