7" lift late 99 7.3 steering wheel vibration

[late997.3]

I have a late model 99 7.3 with a 9" OUO rear traction block and traction bar set up with all Icon in front 3" hanger with 4" leaf springs. I just had this all installed and have a little vibration when starting out in 1st thru 3rd gear. I have no idea what its from and its not bad, but it wasnt there before when I had the 4.5" Icon hanger kit. I am still runnning 35/12.50/20 wheel and tires on truck also. Any info would be appreciated.

Do you have a 4-6 inch dropped pitman arm AND the matching track bar relocation bracket? If so, make sure the track bar drop bracket and upper track bar are tight. I had these come loose on my 6" lift once.

Did they rotate the tires when you had this done? Check balance of all tires especially the rears. Also measure height in wheel wells on all four corners while on level ground to be sure something isn't off causing the drivetrain to be tweaked a little. Sounds like the driveshaft angle is off.

Yeah , I have all that and its good en tight...looking into the angle of the OUO rear block possibly or its just the drive shaft angel. It really isnt bad at all but I just want to make sure nothings going to fall apart when driving...

I did not get the tires balanced or rotated after this just a few days ago because they just did that about a month ago before the lift. I put my summer wheel and tires on a nd they did that.
I am thinking its the drive shaft angel also, but Im gonna take er in next wheel and have the tire shop rotate and balance I thik just to be sure...thanks for the advice also!
