j_jza80 Posted October 22, 2017 Share Posted October 22, 2017 Hey guys, my Supra had an MOT the other day which it passed, but one of the contol arm balljoints was an advisory, so it will need replacing. Looking around on the web, all i have seen is "the balljoint isnt replaceable". Has anyone actually tried it? Looking at the control arm, in looks as if the ball joint is pressed in from the top. Ive got a spare control arm, and use of a hydraulic press, so im tempted to give it a go on that, unless theres a particular reason the balljoint isnt replaceable? Will the existing balljoint be destroyed attempting to press it out, ruining the arm? Thanks Quote Link to comment Share on other sites More sharing options...
HarleyFDMD Posted October 22, 2017 Share Posted October 22, 2017 Toyota dont list individual ball joints so even if you did manage to get it out what would you replace it with? Your only option would be to take it to a 'ball joint shop' and get one that matched.. but then how would you know it was upto the job? Ball joints as im sure you are aware are pretty critical components and if one was to fail at speed then it would be game over. I would just bite the bullet and buy new ones. I bought new rear wishbones a couple years ago Quote Link to comment Share on other sites More sharing options...
Dnk Posted October 22, 2017 Share Posted October 22, 2017 Didn't CW look into this a while ago Think its new arms to be honest if you can still get them or custom arms like the Ikeya type Quote Link to comment Share on other sites More sharing options...
evinX Posted October 22, 2017 Share Posted October 22, 2017 Im waiting for 'blue print copies' to come up as ill go for them, Optimal already produce the front upper ones. As they get discontinued the original manufacturers will be able to re brand and produce them. Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted October 22, 2017 Author Share Posted October 22, 2017 (edited) Think its new arms to be honest It will probably come to that, but before handing over a lot of money for new arms, I would prefer to see if it is possible to experiment with my spare arm and see what comes of it. One of my mechanics tutors has suggested tapping the underside of the balljoint with a grease nipple, and packing it with grease, though I'm not particularly keen on this idea. Toyota want crazy money for facelift suspension parts, equivalent money to newer Ferrari ones. Anyway, the arm is at college with me tomorrow, so i'll attempt to press out the balljoint on my spare arm, and see what comes of it Edited October 22, 2017 by j_jza80 (see edit history) Quote Link to comment Share on other sites More sharing options...

I'm going to go out on a limb and assume that *if* I can find an identical balljoint (and it would have to be identical in most regards), and it is from a similar size (weight) car, then it will work fine.

a98pmalcolm Posted October 22, 2017 Share Posted October 22, 2017 My lower one seized a few years back and the whole arm had to be replaced. I got mine from Keron at Extreme Performance Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted October 22, 2017 Author Share Posted October 22, 2017 My lower one seized a few years back and the whole arm had to be replaced. I got mine from Keron at Extreme Performance I was donated an arm from a fellow clubmember a few days ago, but it seems the balljoint has excessive play. I think i'd rather buy new than pay for a used one that might go very quickly, unless by some chance a low miles facelift car ends up being broken on here in the near future.

j_jza80 Posted October 22, 2017 Author Share Posted October 22, 2017 custom arms like the Ikeya type Rose joints aren't particularly suited to road use, but then again replacement rose joints are very cheap, even if it became an annual job. A pair of Ikeya arms isn't much more than 1 Toyota one. Definitely not going with the likes of Jap-speed or whatever they're called, heard nothing but bad things about them.

Dnk Posted October 23, 2017 Share Posted October 23, 2017 (edited) If a ball joint is already worn then i think filling the joint with new grease will be short lived to be honest I'd personally just bite the bullet and get new arms if available. You could try filling the joint using a grease syringe http://www.suspension.com/blog/how-to-grease-ball-joints/ What is the difference between facelift to pre facelift lower arms ? other than the price Edited October 23, 2017 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Al Massey Posted October 23, 2017 Share Posted October 23, 2017 The reason why I bought brand new arms and bushes from Toyota was the fact that mine lasted 21 years. So I would rather pay extra now for that guarantee then a few hundred every year for a maybe. Quote Link to comment Share on other sites More sharing options...
Scooter Posted October 23, 2017 Share Posted October 23, 2017 What is the difference between facelift to pre facelift lower arms ? other than the price I think it's just a bush change (I'll try and find a thread about it) but I agree having a prefacelift and facelift there is no feel difference and as far as I know no fitting difference, ie same subframe and bolts and shape of the arm.

Scooter Posted October 23, 2017 Share Posted October 23, 2017 Snubbers!? but CW basically explains it but I'd use a new prefacelift arm if (as I've seen) it nearly half the price. http://www.mkivsupra.net/vbb/showthread.php?317525-Stock-facelift-N-A-suspension-vs-non-facelift&highlight=facelift+suspension Quote Link to comment Share on other sites More sharing options...

Scooter Posted October 23, 2017 Share Posted October 23, 2017 I think theyre made of a different, lighter material. Be interesting if true but I think they are both steel of some type so I doubt there can be much weight difference? Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted January 12, 2018 Author Share Posted January 12, 2018 Replacing the balljoint is not possible. Took one into work today and confirmed that as the arm itself forms part of the balljoint, removing one would be without damaging the arm, and fitting a new one would probably destroy the new balljoint.

nellie1966 Posted February 7, 2018 Share Posted February 7, 2018 Hi, Just reading your comments on the control arms, are you happy with them from TCB and are they genuine Toyota as the web site says? Cheers Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted February 7, 2018 Author Share Posted February 7, 2018 Be interesting if true but I think they are both steel of some type so I doubt there can be much weight difference? Compared a pre facelift one with a facelift one today, and there is definitely a weight difference. Not enormous, but noticeable. Add that up across all of the suspension arms and it would be a fair old saving of unsprung weight. The facelift arms also appear to be less susceptible to rust.
