So I was looking at my driveshaft and it's not straight. I have a leveling kit and 35''s. I took the carrier down and measured where it needs to be and I would have to add about 3/4'' of spacer to get it straight.
1) Does this sound right?
2) how much if any are you running?
3) Does it even need to be straight?

Goods news is that the bearing was silky smooth, at 157,000 miles. This all started cause I was getting a slight vibration at take-off. Followed the advice of others here to a TSB from Ford saying to do this.

 

IIRC within 3 degrees is where the driveshaft needs to be.... according to Ford.

 

1/4"-1/2" per lifted inch
Sometimes you have to play with it a little.

Nice avatar, it's not surfing until you throw that rope!

 

I think the general rule is 1/4 for every inch of lift. cant remember how big mine is i will measure tomorrow for ya. Mine is 6in spring lift in rear.

 

Are you getting driveline vibrations?

 

BTW, this bearing you type of is NOT the 'carrier bearing,' those are in the rear-end (and four by front-end).

You're shimming the driveshaft support bearing.

 

Since I actually have to type something.....

 

you ever done that? I was getting ready to throw it! coming in for my beer. good advice guys. so within 3 degrees is good, i think i'm pretty close then. i added 1/2'' for now, test drive tomorrow.

 

The vibration could be caused by it bieng crooked too. Mine did that a little when i first bought it and squared it up and it doesnt vib anymore.

 

I suppose it helps if I completely read the entire post, huh?

 

For years, we went out for a session today actually. Pretty much every Wednesday. One word... ENZO. Best wakesurf boat ever made, best watersports investment I've ever made (I said that when I bought an X-Star in 1999).

Back on topic, how tall a lift?

 

I dont have a lift, just the 35''s. ot- the boat is a Tige'

 

So the vibes started immediately after install?

 

Shim the support after a leveling kit?

What got moved around in the rear?

 

I was just thinkin that, bigger tires shouldnt make that big a difference in the rear as far as the driveline? Did you put bogger tires on it or something, how big is the vibration???
