Okay,

This is starting to annoy me. My rover ball is raised about 2in over stock. I think, I don't know. Since I am moving the lower links, where would you guys measure from? The pivot inside? Perhaps the center of upper links? I don't want the ball to fail, I am kinda hard on stuff. Anybody know what stock is?

If I take the measurement from here I have 8.6in of separation. I have to rotate the pinion up 2 degrees from where it is about.

That gives me this link angle:

Thanks guys!

First, that white PVC won't hold up to what you put your truck through, black sch. 80 PVC is as low budget as I'd go. You should know better than this by now.

Measure the vertical separation at the center of the pivot ball, that's the point where the link pivot revolves around. So center of the ball front to back and up and down.

Where is that?

Wish I still had the ball-joint that I exploded, would be really simple to measure it out exactly. I can't think of how to describe measuring one out on the internet, I'll measure it out on my truck tomorrow and let you know.

That center point is pretty much in the middle of the joint. Or midpoint between the top and the bottom edges of the forging that holds the ball joint.

Does that make any sense? It's too early....

So, a little above where my finger is in the middle of the forging that bolts to the arms?

i see you got the pvc... is it the heat treated kind? :flipoff2:

X2 The measurement should be at the center axis of where the joint pivots. If you have any tir rod end you shoud be able to use this as reference

Once I paint it, it should be strong enough.

Right. Guys. I get that. I thought that before I posted this. What I am after is WHERE on the ball that is! Add to it that the ball is on an angle slopeing foreword and I don't know what it looks like internally, and I am lost as to where to pull the measurement. Where I am pointing in the picture is my best guess.

i.e. in the center of the gray thing in front of and above your finger.

the drawing is of a typical ball joint internals.

Remove the nut and seperate from the axle.

Then move the pin from side to side.
From full left to full right.
Use a straight edge to draw a straight line along the center axis of the pin at both extremes.

Basically / \

Where these lines cross is the center of the ball.

I got like maybe 1/2" above where you are pointing. It was just below the center of the socket when measured top to bottom.

Does that make sense?

I understand your predicament exactly, and think I figured out how to describe it, referencing a tie-rod end is worthless as they're totally different dimensions, may as well reference a zucchini.

Poke around on the top of the ball-joint, unless the D90 is very different from the Disco, the ball-joint should press into an open cup. Fin the top of the ball-joint, that piece of metal is just over .120" thick, and the top of the ball rides against it. Mark the top of the ball on the outside of the cup. Now poke the rubber boot with something that won't mangle the rubber boot and find the end of the taper, that's the bottom of the ball. Find the center-point between the first mark and the bottom of the ball and you've got your point to measure off of +/- .250". If you want to get it even closer than that move the axle up or down until that ball-cup is level, or buy another ball-joint and cut it up.

First question:
How accurate do you need to get it? I'd have thought within 10mm would be fine.

Unbolt the joint, push the threaded shank over to one side and scribe a line up the housing along the line of the shank.
Push the shank over the other side and scribe another line. Where these two lines cross is the centre of the ball.

Awesome idea

Thanks guys.
