Thanks trident!
When you say that the jag part is "not designed for spring loads", is it not used in this way on the DAX?
I presume that he SAAb part IS designed for spring loads?

I was thinking the same,the Jag part is a TOP ball joint,why isn't it suitable? I was planing on using these on the 40

Definately, at least the track rod ends I have seen have had springs to preload them, thats why they are so stiff to move. I can't imagaine
them lasting 60,000 miles plus if they simply relied on the fit of the ball in the socket. Just like rose joints, the tinest bit of wear and they
would get very sloppy.
Don't need to destroy it to check, just clamp it up in a vice.

It is not designed to takes any weight in the plane you want it to. On the Dax it does not carry any of the cars weight, it only stoppes the wheel
from falling over, the load is carried by the bottom joint.
In a normal Locost the bottom ball joint takes the weight and is used in tension. A Transit drag link can also be used in tension. To use a rocker arm
suspension you need a joint that will work in compression. The point that BT is trying to make is that tension ball joints have a spring that pushes
the ball onto the joint preventing play, when you then put this joint in compression the spring is then taking the weight, not the ball, and the ball
will move out of the cup, leading to play, and joint failure.
DO NOT PUT ON KNOB OR BOLLOCKS!

It is a Jag XJ6 & MK10 top ball joint.
On Jags the spring (or in the case of the E Type the torsion bar) works on the lower wishbone much in the style of the Mk3-5 Cortina, the Jag lower
ball joint is massive.
On the SAAB and the Triumph Dolomite/1500 the coil-spring-damper unit acts on the top wishbone pushing the ball joint down into the cup.
(To explain a bit Standard-Triumph did a lot of the design of the original SAAB 99 for SAAB --- pitty they didn't keep it for themselves)

Thanks chaps, looks like the SAAB joint is the one to go for if I can settle the other issues with the top rocking arm set-up.
cheers

Taper on the SAAB balljoint is unkown, of course it would also be possible to use SAAB up rights with gutted CVs --- istr PCD is same as Ford up to
the GM take over.

Shoudn't be a probem mate - It's being fitted to a fabricated upright, so the hole can be reamed to fit the joint.
