Easy driveshaft question
I have a driveshaft out of a 2005 F250 Supercab SB. It is exactly one inch longer than my factory Excursion shaft. I have F350 blocks in the rear (raised almost 2 inches). Will this driveshaft fit? I have several posts about my vibrating Excursion. If this would not bottom out, I am willing to try it. If you are not sure, what is the best method to see if it will work? This driveshaft has the factory rubber dampener where mine does not.

Yikes!!
Having read all three pages of your vibrating post I can see the incentive to try the other shaft. One inch difference should not be an issue given your minor lift. I shouldn't think you would have a problem unless you fully collapsed the rear suspension, which would probably cause other problems.
Did you ever get the CV joint? Mine has it (stock) and there hasn't been a vibration problem either before or after a 5" lift.

No CV yet. I stopped the shop when I took him the yoke from the spare driveshaft and he said it used a 1410 Ujoint and the X uses a 1350. They use the same joint. He is wanting to put it (CV) on the pinion side also. I wanted to try this driveshaft and see if it fits. I have a week and a half before going on vacation. If I dont get it fixed, we will have to take the wifes Wrangler Unlimited. I bought the X for this purpose and am determined to do all I can to get it fixed.

absent some really wierd issue like an out-of-round out-put shaft on either your tranny, or input shaft on your differential, I would BET you could solve your vibration issue (again, assuming it is really a drive-shaft problem) with having any half-way competent drive shaft shop make you up a drive-shaft with CV joints front AND rear. Drive-shaft shops generally know what they are doing as to "phase" and "balance" issues. Not cheap, but that should do it. Of COURSE it is REMOTELY possible that you have other issues (engine or transmission problems - a road-wheel machined off-center) but you have to start somewhere !

yeah - some humorless kid got upset over my teasing the diesel and "raised" guys, figured out how to get me banned, supposedly for two weeks. Two weeks have passed, but he wont let me in. So I simply re-registered ! Be assured I NEVER EVER use rude, vulgar, or "fowl" language ( I cant speak "bird"...!)

Absent info from someone who has a +1" DS on a +2" lift Ex, I 'll add my .02 ...
Because the rear shackles are inverted (fixed end down), when the axle is unloaded the driveshaft will be pushed forward. And pulled back under compression. So you can see how much room you have after the 2" lift by jacking the frame and lifting both tires off the ground. Just remember that in the real world, if you droop both rear wheels the suspension will move a little more.

I am planning on trying this tonight. I was going to do it last night, but discovered my hubs were not releasing. I had to pull them both and clean / grease.
Will report back when I try it.

Thanks everybody. I feel like a nuisance for posting so much on the same topic. But on the other hand, it may help someone else in the future when they search for vibration. I know it has helped me. I have searched various forums myself for this issue. As far as vacation, I (as well as the wife and kids) hope I get it figured out as well. Her Wrangler Unlimited is nice and all, but we would be limited on what we could pack and the kids comfort is obviously not the same. I ended up buying an Excursion that was used and abused. At least I know the oil and transmission fluid had been changed.

Update- I tried the old / new driveshaft last night. It was quite interesting. I am vibe free until around 68. At that mph, it is evident, but barely and stays that way until about 73 or so mph then it quietens down some more. Major difference between the two. The F250 shaft length wise is too long for my tastes. The end of the splined portion is at the end of the opening on the slip at ride height. This leaves a finger width between this and the Ujoint. I am taking the driveshaft to Fleetpride and he is going to replace both ujoints (Spicer), cut it down and balance it. Should be done Monday. An interesting fact evolved yesterday. I called the dealership that serviced the X (prior owner). They had extensive maintenance records on hand. I asked about driveline issues and sure enough, she took it in at 35,000 miles complaining about a roar in the driveline. They replaced the driveshaft and pinion bearing. That explained why I found one pinion bearing a different brand when i went through it. She then took it back at 70,000 miles complaining about the same thing and they could not find the cause.
At least I am not crazy. But, this tells me it is not a new issue. I honestly think a CV will totally fix it, but for now I will try this so i can take it on vacation.
