Colin Fairhurst Posted May 8, 2018 Report Share Posted May 8, 2018 Can anyone tell me is the taper on the TR4a outer ball joints on the steering different to the ones on the TR2/3a? If so then the steering arms are obviously not interchangeable . Regards, Colin Quote Link to post Share on other sites
RobTR3 Posted May 8, 2018 Report Share Posted May 8, 2018 The Moss parts catalogue shows different part numbers for steering levers and outer ball joints vis a vis TR2/3's and TR4's. So there would be a question mark on their interchangeability anyway. I have no idea about the different ball joint tapers if there is any difference, but I don't think that's the real issue.

Colin Fairhurst Posted May 8, 2018 Author Report Share Posted May 8, 2018 Hi Rob, I was aware of the different part numbers and the TR4a outer ball joints are very different to the TR2 because the TR4a has rack and pinion. I was thinking that if the actual taper was the same then with my particular set-up the TR4a steering arms could be an improvement. Regards, Colin Quote Link to post Share on other sites
RobTR3 Posted May 9, 2018 Report Share Posted May 9, 2018 Hello Colin Have you considered the Revington modified steering arms and longer Tie Rods? You can then use the same ball joints. I have this set-up on my TR3 and it does improve the steering by eliminating bump steer and improving turn in. Rob Quote Link to post Share on other sites

BlueTR3A-5EKT Posted May 9, 2018 Report Share Posted May 9, 2018 Taper is different on the TRE of sidescreen cars to wind-up window cars. Quote Link to post Share on other sites
Colin Fairhurst Posted May 9, 2018 Author Report Share Posted May 9, 2018 Thanks for the information. I think my question has been answered. Rob, I think that's the direction I will go eventually. Regards, Colin Quote Link to post Share on other sites
RogerH Posted May 9, 2018 Report Share Posted May 9, 2018 As an aside somebody told me recently that imperial and metric tapers are different. The imperial taper is 1:48 The metric taper is 1:50 (just to be bloody different) So do modern TBJ and TRE with the metric nut have the metric taper !!!! It may be worth bluing a joint to see.

Ian Vincent Posted May 12, 2018 Report Share Posted May 12, 2018 And on the subject of track for ends, what do you do it you have the nyloc nut half way to being tight when the taper starts to slip and turn rather than being pulled together? Rgds Ian Quote Link to post Share on other sites

Rgds Ian I try and get a lever of some sort over the ball jont to keep the pressure on and do up the nut until it pulls together on its own. H Quote Link to post Share on other sites

Try using a plain nut first until the taper is tight, then change for a nyloc Cheers, Mike Quote Link to post Share on other sites
Lebro Posted May 12, 2018 Report Share Posted May 12, 2018 I like that idea, I usually tap (hammer) the tapers together to lock them. Bob. Quote Link to post Share on other sites
