I recently purchased a 2003 X with the 6.0l. When I drove it home it wandered all over the road. I explored the forums here and read so much, with so many differing opinions that I was completely confused.
Axle Wrap - soft Springs - Rear Sway - X codes, Vcodes, Steering Box, Ball Joints .... on and on..
From someone that does not do their own work, and does not know how to, I will say this. I changed the ball joints. as they needed to be changed, and the sway bar links were bad as well, changed those.
changed the steering box to a stock replacement from the dealership, 725.00 out the door and WALA! all fixed. steering is tight as a drum. no play, no wandering no nothing. A pleasure to drive.
Now I appreciate the advice on this forums and it educated me so much on the excursion, but biting the bullet on the cost was the hardest part. but I dont regret it at all.
For information, my X is stock height with 20" HD wheels and 34's. I just purchased a new ICON all spring lift of 5" and some new 18" Artillary wheels with 35's. I did that because of all the information on this site.
so thank you all for costing me 5 grand !
and fixing my steering issue
