OME CS005's = Too long a rear driveshaft?

[ntsqd]

That is where I'm at. Had to literally pry the rear flange over the end of the pinion shaft to get it in place. Obviously I'm not going to drive it this way until I get it figured out. Mil wrapped leave is in the hanger and not in the shackle, though the load leaf strap is forwards of the center pin which is exactly opposite of what I'm used to mini-trucks having. I had originally hoped that I was just getting a grease semi-hydro lock in the slip, but it hasn't changed - no grease oozing out anywhere.

What did I miss?

Try removing the zerk on the slip yoke, see it that relives any pressure. I know my stock driveline was pretty tight, but not like you're describing, I had about 3/8" from bottomed out.

Is the truck up in the air, or weight on the tires? They'll settle if up in the air.

These are CS005's going in, and my rear seems a little forward, too... But I haven't got it on the ground yet.

Thanks!
I'll try removing the zerk and see what happens then.

It is on the ground. I can see that compressing the springs will go in a good direction. What I'm not sure of is where it will go in extension. The axle will move forward in extension, but what I don't know is if it moves enough to offset the length increase from going down.

My truck has OME medium's in it, CS004RA/B, and getting my drive shaft in when the suspension is @ full droop is very tight! try putting some weight on the axle and it should go in easier.

I pulled the rear D-shaft to replace u-joints, and had to shoehorn that sucka back in. This is with original bone stock springs installed.

Just to be clear, the weight of the truck was on the suspension when I attempted to reinstall the drive shaft. I had to use one of the ~18" long prybar/screw drivers to convince the piloting ring on the drive shaft flange over the end of the pinion gear. It is not under compression just sitting there, but there is very little compression travel available in the drive shaft's slip, say less than 1/16" (1.6mm).

I worked a 14 yesterday so I've not yet had the opportunity to see if removing the zerk relieves any 'hydro-lock' effect from the grease in the slip. It would be nice if this is the problem, and that the fit of the slip parts is tight enough to not allow the grease to ooze out. My hopes aren't high though.

GTG!

Turns out that the slip spline is sealed well enough to keep the grease from oozing out. I finally got some time to mess with this and as suggested I pulled the zerk out of the driveshaft. Strange looking mixture of grease oozed out and then I had plenty of plunge available.

Now to cure the Stink-bug stance.......
And install rear disc brakes.......
And do the engine swap......
And......
