do you have a lift on it for the big tires?if so, how high? just a thought...

The best solution would be an anti-wrap bar connecting the axle to the frame. A few companies make them. Looks like a single ladder bar, mounted perpendicular to the axle, with bushings on the ends. If I find a thread with a pic or link, I'll post it, JSM84

sounds like you might need a longer driveshaft.

Replace with the blocks with a set of lifted leaf springs. I ran 38's with 6-8" inches of block under the factory springs for a short while. The rear always moved since it pivoted on the blocks. I installed a set of 6" procomp lifted leaf springs for like 350 bucks. Never had another problem. Articulation was a tad better too.

hey how was the rest of the factory drive line on the 38's after the axle stopped wrapping up?

I think for the most part the driveline held up for a F150 on 38's. I broke a few u-joints in the front axles. I never broke any joints on either driveshafts. I had 8" of suspension lift which caused binding on the front driveshaft at the yoke on the transfer case, without a cv. I had a stronger slip yoke installed and just machined the yoke's a tad and never touched again. Only had one rear axel snap, but I think that was from age with stress. I had 4.56's with a detroit locker in the rear and truetrac in front. I would suggest against a truetrac if running 38's. I ended up toasted mine.

hey do you know if a 1330 yoke fitts right in to the 9 rear end? and is a cv yoke better than a non cv yoke?
