pufferfish said:just be prepared for the possibility of needing adjustable UCA or LCA's...even with the DSS. both have documented cases of vibrations. both have been able to be solved with proper pinion angle adjustments or sometimes just clocking the driveshaft 180 degrees. theres no magic bullet to bolt in a 1-piece driveshaft in place of a 2-piece. there's a reason ford put it in there. think about it. if CV's were vibration slayers, why didn't ford put in a 1-piece just like the DSS? it has to be cheaper than that 2-piece with a carrier bearing. the 2-piece is in there because only a 2-piece can make up for poor factory geometry.
since we are on that, my theory is that moving from a 4link to a 3link got ford better traction, but more drivetrain noise. so, they loosened up the bubber compound in the bushings to make them ultra-compliant and reduce noise. this is why the s197's have issues with using a 1-piece driveshaft. the "loosey goosey" factory 3rd link can't control pinion angle. thats my conspiracy theory anyhow.
again, i am not trying to sell anyone on the Dynotech shaft or steer anyone away from DSS. i just want people to be informed. i would want to know if an item i was buying had even a 1% chance of not working as is.
I can deal with the 1%. If I have to make an adjustment from the start then I'm not to comfortable with that. I still need to educate myself on this before I take the next step. This is uncharted territory for me and I'm not ready to jump in to it yet. It would be different if I had someone with experience to check my work. I'm not a fan of going to a mechanic, I'm sure there are good one's around here, but it's like blind faith until I do, and I lack that. I normally do things myself, or take to a dealer if I cant do it. I'll post on the club forum I belong too, maybe there is a do-it-yourself shop with a mechanic on standby around here and, I'll see what happens.
