holy wobble, please help!!!!

So i recently went from 6 to 8 inches of lift up front. I have a basic fabtech readius arm drop kit. I now added a leveling kit under the coils to give me an additional 2" of lift. At the same time i rotated my tires crossing back to front. So now for some reason when im cruising on the highway it pulls to the left, even worse if im making a right turn it vibrates like crazy, but if im making a left turn its smooth as can be. Also when im on the brakes sometimes i can hear a donk donk donk noise.

Before i did the extra 2" and rotated the tires, it pulled to the right a little and even more when on the brakes, now it does all this described above.

Any thoughts??

I would recommend getting an alignment if you haven't had one recently, especially to see where your caster is at.


So you rotated tires and now the pull changed from the right to the left? Could be the tires.

I was maybe thinking it could be the tires as well. Im really hoping an alignment will help it though, maybe a balance too.

what did you do in the rear for the lift? mine has a knock when i take the steering wheel through a spot little to the left and then on the way back. The pulling is probably a result of the tires. They will wear one way then you rotate then it pulls the other way. let them ear some more and it should settle out then. The wobble i dont know. Mine did it the other night to where i stopped and looked at eveything and then it hasnt done it since. So I dont know. Hope you can figure out whats going on.

I didnt change anything in the rear, i just added some lift to the front. I would think my ball joints are fine they were just replaced maybe 7k ago. I think the pulling is from the tires but the violent shake and donk donk noise is what im more worried about.

Fixed the wobble by re-tightening everything, I guess something was loose. It still pulling which should be fixed with alignment and or tire balance.

pulling is in the Castor adjustment or not the castor but more specifically the cross castor or the difference in angle from one side to the next. You should aim for the closest possible number there but if not favor the right by having more angle on the left. Im not sure about fords yet but on a dodge you mark the position of the cams before you take them loose then as long as the new arms are equal you can return the cams to the same position and have more or less the same cross castor.

thanks, its going into ford soon for studs so im going to just have them allign it and that should sholve the problem. I also found a screw in my left front tire causing it to loose some air pressure. I have since plugged it. It has helped the pull a bit, but it does still pull to the left a little, unless im on the breaks then it will pull to the right a little. I also found a broken abs sensore wire on my right front tire, which would explain the ABS light lol. I already ordered the parts to fix that, not sure if it would have anything to do with why it pulls to the right when breaking.

When I got my dodge lifted the bolts kept coming loose and I neglected it and they actually egged out the bushings so It never did drive right and I ended up lowering it back to stock...
