ball joints, top?

Post by steveb » Sun Apr 30, 2017 1:09 pm

ball joints? top ones, the ones i was using have a 20mm thread, book's seem to be 18mm.
So has any one brought any recently and from where?
my local autostop in East Tamaki showed no stock of
the numbers, if the numbers did work. numbers from the Haines book.
it seems U.K may be the way to go, any answers?

DMC, yes thanks, i saw the rally design upper and lower (maxi) ones,
they don't do a freight estimate to here, kinda, buy the parts and
absorb the freight, the price we pay at the end of the world...
how is your build?

Rally design is pretty good on freight, and the landed price will still be cheaper than what you pay in NZ.

called into BNT, part number works, but only one in country @ $37+gst.
So yes, rally design units are 7 ish pound, $14.00 therabouts,
Once again its easier to import privately, I do try and support the local market first,
but it's getting harder,

You might want to have a chat with your certifier regarding the use of a tie rod end as a top ball joint. 7ish had with his McGregor build. Also I discussed it with my certifier and he explained the reasoning behind there dislike of using tie rod ends as ball joints.... they are just not designed for use as a suspension part.

Re: ball joints, top? frasers!

Post by steveb » Sun May 07, 2017 8:42 pm

just looked at frasers site and there is what looks like a transit link, but its sold as a cortina top ball joint.
How say you certifier's. if it is sold as a ball joint, is it a ball joint???
doesn"t almost every 2nd seven on the road use this setup? locost, fraser, mc greggor, most of the english??
So 7dreamer what did you use as a top ball joint, does it allow camber adjustment?
thank's.

Caterham use a Lada tie rod end as top BJ, can't get any better than that.

First off i will say i know the status quo works and works well and has done on thousands of lotus 7 type cars. I had a discussion with a certifier after i saw the drama 7ish had on his McGregor build and I wanted some clarification for my own very slow build.
I am using holden gemini uprights so in a slightly different boat to most here. Currently I have toyota tie rod ends which I'm unhappy with. By pure chance honda civic top ball joints work for me and a quick search of tradme will show that the tuner market has made a ball joint that will allow camber adjustment so I will use these on a new set of a arms. It will depend on your certifier and there opinion of wat they find unacceptable. Simply a tie rod was never designed as a loaded suspension compoment to take vertical shock load they are designed to transfer lateral load to the upright and get dragged up and down by the suspension movement. Hope that makes some sense.
Pete.
