Cranking torsion bars too much??

No. Ball joint flip makes alignment easier after a lift.

Billy, the dropped diff certainly causes failure. The prop shaft was designed to always stay at a certain angle, not like the CV joints. As illustrated in the photo, there is not much room for angle change. Less than an 3/4" in play in either direction. The cuff was not meant to flex either. I would be curious for those with diff drops to crawl under the truck with a light and see how much metal deformation has occurred, and if their cuffs are ripped.(Only my front ones ripped) How many have actually installed diff drops? That would be a good survey

I do agree that even without the drop, the cuff can tear, but much the same as a CV, keep adding grease, stay out of mud and water, and it will probably last years. My wife has a torn CV boot, haven't had a reason to repair it, if the CV gets noisy, there are lots of troopers in the yard

I've had the diff drop for about 5 years...


...and no cuff issues... YET!


Good to know though...
..and luckily I have a spare complete front shaft if I ever need it

It depends on how much you dropped the diff. At the time, I was nose high in the air on the front end, and Joe did a decent drop, will need to measure to see how much. I would say an inch is probably fine, and does a world of good for the CVs, so well worth it IMO. I will not be repalcing the shaft again, I will have one of the shops fab a universal joint shaft to go in its place. Shouldn't be too expensive, hardest part will be keeping the original bolt pattern, or fabbing an adaptor to make it work.

Mines a T/bren drop...so 2.5 inches IIRC

Lets see what your poll results indicate.
