Hey guys, I just got done putting in a 6" lift in my 95 f150 std cab shrt box. I noticed the yoke on the drive shaft is sticking out about 4-5" more than when it was stock. I didn't think it should be this far out!? And I'm not sure i really like the angles of the driveshaft. I was wondering, I know they make driveshaft spacers but would that help? I'll take some pictures this afternoon of what I'm talking about. Just curious on if this was normal or not.

 

Well, when you lower the axle, the driveline has to take up that extra distance somewhere... What are these spacers you speak of?

 

they go on the rear axle yoke, between the driveshaft and axle. Just a simple spacer that is suppose to put ur axle farther back into the tailshaft... i dunno sounds kinda dorky to me but if it helps until i can get a new drivershaft.

 

Ah ok, do you have a link to this thing somewhere, just want to see how it all works.

 

he doesn't have a traditional yoke on the 8.8.......its the flat yoke style.....so id imagine it would just be a spcer that went in between the flat yoke on the 8.8 and the flat yoke on the dshaft......

 

Sounds like crap to me.

Have a longer driveshaft made if you want to do it right.

 

agreed.....

Having it lengthened shouldn't be much over 100 bucks, and it will help your drive shaft angles more than a spacer, by keeping the yokes as far apart as possible

 

How much lift is there?
The OP mentioned that the driveshaft angles were also a little off. If the pinion angle is not adjusted, this will add to the length problem, and promote vibration, and shorten joint life.
You need to address the pinion angle problem. It should be angled up towards the transmission to decrease the working angles of the joints. This in turn will move the pinion yoke (flange style, very strong) closer to the transmission, and you will move the slip yoke back into the transfer case.
If you are running a block in the back, look to see if it tappered. The small part of the tapper should face foward. This will pitch the pinion up, and help cure angle issues.
6 inches is not a whole bunch, and should not require a new shaft if the angles are correct.
The aftermarket is full of longer flange style yokes, and is a cheap alternative to replacing an entire shaft. A complete shaft can get expensive.
While the new flange is a better option, spacers are actually a reasonable solution (not to exceed 1"), since the flange is flat, a spacer can be used without excessive stress on the mounting bolts.
I have been beating the snot out of a front driveshaft in a Super duty for years with a 1" spacer.
Fix the pinion angle, and you should be fine. I doubt that you even need to lengthen the shaft. You will be suprised when you fix the pinion angle how much further the yoke will go back into the case.
Good luck

 

While not ideal, there should be nothing wrong with using a spacer (if you can find one) on an 8.8. All it really would do is make the flange itself thicker, similar to a wheel spacer, but there would be side to side torque on it like a wheel, just rotational force.....when i lifted mine i couldn't find a shop around here that would lengthen my driveshaft....they all wanted to build me a new one....so i just blew it up with a bad ujoint and had a whole new one made...LOL....

 

std cab short box is as short as you get besides a bronco (they need lengthened shafts for 6inches) so its possible he needs a new shaft.

but i agree, get the other issues resolved first

 

x3 on the bad idea. With a spacer, you're making the arc of pinion change from axle hop and compression long. Could bust a u joint from just stepping on it and it binding. How much of a extender is this spacer?

 

I never actually found a space for this truck, I just have seen em for other vechials. I think the problem might be the lift came with 5.5" lift blocks (eww) so I bought an add-a-leaf and a 2.5" lift block. So the shim angle might not be right on the lift block?

 

which way does your pinion point?? up or down?? of its down you have the blocks in backwards if htey are tapered for pinion angle. if they point straight you need to make it point up.
