For being an "easy" adjustment...pinion angle has a lot of shops worried. I called like 4 places. 1 shop wouldn't let me spend money with them because they were sure it was a drive line balance issues. 2 shops where sacred to touch anything. the last place had to ***** to check it but wasn't sure if he could get wedges to fit and thought maybe he might have to cut preachers to and roll the axle until it was at the right angle........ but he could check it for 30 bucks..so maybe ill let him get that far.

Oh another shop said I needed an aluminum driveline because "in my situation" they can't balance the DS close enough and or set the pinion angle close enough to make it work so they just let it stay fu**ed up and reduce the rotatining mass so you cant feel it vibrate....

Gun,

This has got to be getting irritating. Call Denny's an ask them for an opinion. I've always had great support from them and have purchased 6 or 7 drive shaffts for some strange combinations without issue:

They will be providing the driveshaft for my 66 fastback with TKO600.

Im only about 50.00 dollars away from you..but I haven't quite exhausted all my options yet...I think I can talk the first shop into checking pinion angle even though "there is no way" its the problem... I do think they are quite capable of it...I'll try a different approach with them tomorrow

Then maybe ill come visit.

Thanks

That's pretty funny. I have a longer drive shaft than you, it's steel, AND it's 3.5 in stock. No problems. "I can't fix it, but I can sell ya something "that might fix it.""

can't wait to see if you get it fixed. as said very similar setup and problem. i didn't go for dennys as I planned to change leaf sprigns which is just done (knowing that that might again change my pinion angle). but if it's not healed now I'll probably do the same. get a ncie new alum balanced shaft exact to measure.

edit: i remember that you measured your angle in the opast and seemed correct. I actually had to cut/turn/weld my spring perches because they were in the wrong place to start with when I received axle. I'm quite convinced that our problem is the exact same.

Do you have a dust rubber cap on the back of your T5? and how far from that does your yoke stick out from that? i can measure as well to compare, but it'll be 3 days until i'm back at car

Well, looks like you have alot of good info, but I thought I would through my 2 cents in. I 've read through the posts and I was just wondering if you have checked the run out of the axle pinion flange? I have seen the same thing happen where everything was balanced out and it still had the vibration. Did you try removing the d/s and rotate 180 deg. at the rear flange? Also as far as shims go you can find them at a good spring shop or check some Jeep parts sites, Jeepers are always screwing with drivline angles and such.

Good luck! Keep us posted so we can all learn.

Good call...Actually one axle was bent and had about .012 to .015 runout. Again a much different vibration it was heavy and made the windows rattle and you could feel it in your face ...literally. This vibration got progressively worse and did not increase when throttle was let off.

Both axles were replace with some "tom's kick *** axles"

that was before the t5 swap.
