I've got some g40 TCA with the rose jointed inner joint but the outer ball joints are worn out, dose anyone know if there is anywhere you can get new joints put in or refurb kit so I can do it my self, its only a pressed in ball and socket,
You can't get the g40 TCAs anymore so don't want to chuck them!
Should be able to find a couple of sites in Classic Car Magazine and suchlike.
this guy does the trick quite well

kool thanks guys
Would it be worth getting the rose joint done to?
where do you get the little rubber boots from? on its own? and same for the track rod ends, mine are split but in perfect working order, and yeah can you not push a rose joint into the inner one?

ebay!
that's a cool video, I might give it a go with an old TCA. What is he welding part way through though? Is he just doing that to get some heat into the metal to push the ball joint outer casing out? (and/or welding a ridge to push it out with)?
Yeah i thought about getting an old one as well. Wonder what size ball joint will be needed?
I would of thought it would be to do with getting it really hot, as it would expand then quickly cooling it to make it contract so it comes out easier.
Will send him a message on youtube.
He grinds the old balljoint down to separate the ball/thread part from the bearing and smashes the ball/threaded part out. That leaves the bearing race in-situ, so he runs a bead of weld around it to get it hot before throwing it in the water to make it contract uber-quickly and drop out.
As Andy said- it also works if you leave them to air cool, I've done it on a stubborn wheel bearing race before, bead of weld round, allow to cool, weld/race contract and pop out.
Neat trick providing you don't weld the race to the housing...
it cant be to hard to change them tbo as long as we can find the right size joint to put back in i might try to get mine out soon, would be nice to save the g40 tca's. will let you know how i get on
Dose anyone know if the rose joints can be pressed out? Or are they in with cir-clips (haven't look yet) Been looking for replacement ball joints cant find any in the size I want so im thinking of taking the rose joint out getting standard arms and getting them machined so the joint can be pressed in because standard arm inner diameter is smaller and tapered for the bush to fit.
Right Ive managed to press the rose joints out! So I'm going to buy some standard arms and get them machined out so I can press the rose joints in hopfully if the standard diameter is smaller witch I'm sure it is.
I will get some pictures up when u get the measurement
This could be awesome! Any ideas where to get just a rose joint from?
Haven't a clue as I'm using my g40 ones but will be hard to find some tbo unless u modify the arm itself or just make ur own from scratch like ppp ones
right so its worked :)
firstly i pressed the rose joint out the g40 TCA and pressed the bush out the standard one i got off my mate to check the inner diameter as u can see the standard on with the bush (top one) has a smaller inner diameter so i went ahead a ordered so good quality standard TCAs

so i got my new standard TCAs and pressed the bushes out got my two rose joints from the g40 TCAs

sent it to my local machine shop and asked then to make it a press fit
few days later

so i got my g40 rose joints and pressed them in at work hoping that they will be a snug fit

they were perfect took 2 tonne of pressure to put them in so perfect really

cleaned up the dust covers and holding rings

and pressed out the outer bushes ready for nylon ones :)

so ive just painted the outer part of the rose joint so it dont rust then ill pump them with grease put the dust covers back on, put the nylon bushes in and ive got myself some new g40 TCAs :)
Luckly my rose joints have loads of life left in them but when they do wear out i will get the measurements i need and get some proper spherical ones:)
over all the new standard TCAs were £41 for both
machining £45 for both
job done :)
Awesome!
good stuff! I guess you could do the same with the outer bushes too, machine the bore and then press fit a suitably sized spherical bearing to that.

Would that be better than a nylon bush?
Could be onto something there ryan :)
I guess it could work as long as it was a bearing and not a rose joint plus you would probably need a cer-clips to hold he bearing in as I wouldn't want to rely on the press fit to keep it from moving, tbo nylon ones do the job pretty well I think but deffo one I will look into! :)
