Shudder while driving

[04strokerdissel]

I own a 2004 F-350. While driving it has a shudder at 25, 40, 55, and 65 mph. I thought at first the tires were out of balance but then noticed it has a slight knock when I come to a complete stop and then again when I accelerate. It is not the transmission, I know this, but I was thinking it could possibly be the degree of the driveshaft. The truck does have a 4 inch front and 2.5 inch rear procomp lift but I wasn't sure if that was enough to throw the driveshaft out. Wanted to get some opinions before I started tearing into it and spent more money than I have to. Any info would be great. Thanks

Could be a wheel bearing, or bad ball joint.

You didn't tell me it knocked earlier, check your u joints in the driveshafts. Thats what mine was doing. Try and catch it before its too late and costs ya a whole new yoke...TRUST ME... that is assuming it is a ujoint

You may need the carrier bearing drop bracket. I'll bet if you dont have it the u-joints wore out prematurely. If you do get new joints, look into the drop bracket...
