Wishbone balljoint on Avon - thread issue
Hi, I recently purchased a 99% complete Avon and am finalising things prior to SVA. I have noticed that there is no additional thread appearing on
the underside of the balljoint to the front wishbones - is this required for SVA? See pics
If this is the case can this nut be shortened and then split pinned or do i have to get new ball joints due to the ones tiger providing not being
suitable??
Any help would be appreciated!

You sure the nuts is fully done up with the car bearing the full weight of the car? I had a similar problem with my car (I even had some nuts turned
down into half-nuts) until I did the nuts up properly.....

Was gonna say, the ball joint cover always looks like a rubber "donut" when the nut is fully done up.
Id try jacking the upright up an bit and putting a bit of weight on the top of the ball joint. It sounds like the pin is spinning in the upright as
you try to do it up.

Suspect you may have the wrong ball joints? Some do not have a long enough thread . Might be worth doing a search on here as this has been covered
before giving the correct parts numbers IIRC .

Looks to me like it's not fully engaged. I'd try jacking up from underneath the wishbone (as mentioned above) to try and make sure the BJ
is fully into the taper in the upright. You might need to "wiggle" the ball joint when you do this- it's quite easy for the ball
joint to be going in at an angle and jam slightly sideways. If you're jacking from below and you wiggle the BJ it might unstick and click futher
into the taper. If you've jacked it up high from underneath you might need to "wiggle" it with the help of a few clunks from the
sides with a rubber mallet...

Check for dirt or paint on the female taper.

Do a search for upper ball joint threads by The Doc 10/08/07 and also one by Ben B transit balljoints doesn't protrudefar into cortina upright
9/4/07 May be of help . Still haven't worked out how to put a link in.

just an observation might save you problems later on, But SVA don't appear to like plain braided hoses, could graze your legs, would suggest
spiral wrapping.

Avon thread issue
Hi thought I'd add that Tiger recognises this problem for some ball joints that don't have a long enough thread and suggest the drill and
split pin route. The ball joints I fitted did have a long enough thread to show some on the other side of the nut so the nylon insert was locking the
nut. The book from tiger has notes on this so it might be worth getting it. Also has suspension set up details, dimension etc. It does have a
reputation for inacuracies in some the dimensions quoted on the chasis diagrams but still usefull for other bits. I'd try second hand on ebay or
amazon its perhaps not worth full price but then some of the info will help you so take your pick I guess

You could also try using a plain nut to pull the balljoint down then take it off and then put on the nyloc nut.

i have the same problem with mine (rocket with cortina uprights) they dont seem to sit low enough in the upright and i was considering milling the
uprights alittle at the top to fit the ball joint... would it just be better to get ball joints with longer threads then ?
