StuartG Posted January 27 Report Share Posted January 27 After reading an article in the latest TRAction about rear stub axle failures and the possible life threatening consequences I am a bit concerned ! Is there any way of checking these or should they be replaced every ?? thousand miles as a precaution ? Thanks........ Quote Link to post Share on other sites
Macleesh Posted January 27 Report Share Posted January 27 (edited) I think the only way to test them is to send them for None Destructive Testing (NDT) Not sure there's a mileage factor involved, they've been breaking since the IRS system came into use. Personally I decided not to take a chance and fitted CDD hubs when I converted to their CV driveshafts. Edited January 27 by Macleesh Quote Link to post Share on other sites
RogerH Posted January 27 Report Share Posted January 27 (edited) Hi Stuart, indeed when failure happens the situation is not good. You lose a wheel and the brakes are compromised. There is no way to test if and when failure is likely. You can test to see if a crack is present but that may b e too late. These axles have done quite a few decades of work with an unknown history of kerbing, fast corners, etc. New ones are available from Moss and Bastuk. My Moss hubs are still running very well after 6 years. If you do consider a refurb it MUST have NEW axles (rarley carried out) Roger Edited January 27 by RogerH Quote Link to post Share on other sites

Personally I decided not to take a chance and fitted CDD hubs when I converted to their CV driveshafts. NDT will only tell you that they are cracked. You will not know how much life is left if NO crack is found, Thus NDT is useless in this case. The TR cars have had a reasonable history with these axles/hubs The Stags less so. New hubs should give you many years of reliable service There have been failures with the CV hubs. Roger PS - having just read Neil's comments I agree totally with what he says.

StuartG Posted January 27 Author Report Share Posted January 27 Thanks for the replies, I will look through the cars history file to see if / when they were replaced. Quote Link to post Share on other sites
Z320 Posted January 27 Report Share Posted January 27 Hi Stuart, I don’t know what is written at TRAction, this is what I did years ago because of that issue: the play of the rear hubs is a pain to adjust new, and because I noticed a noticeable play there my thought was —> why! I immediately ordered new ones from Goodparts and gave no thought on reconnecting the original ones and spent any more worry on that problem. Ciao, Marco Quote Link to post Share on other sites

That statement is neither quantifiable or can be proven. Triumph IRS is generally robust & long lived. In recent years there have been rear hub failures, possibly due to hubs being rebuilt and the stresses put into the components on disassembly. Personally I wouldn't rebuild one Jerry Quote Link to post Share on other sites
RogerH Posted January 27 Report Share Posted January 27 Indeed, it is easy to recall one failure and at the same time ignoring the 10's of 1,000's of long lived units. Roger Quote Link to post Share on other sites

SirHector Posted January 29 Report Share Posted January 29 I think Goodparts hubs maybe selling fast now!…….or people just fit new OE again from Rimmer/Moss!!???? They look a great piece of kit….. How much sent to the uk I wonder? ££££ ….. birthday soon lol Quote Link to post Share on other sites
Z320 Posted January 29 Report Share Posted January 29 I bought my Goodpart hubs from a German TR parts trader and had no worry about delivery and custom fees. Quote Link to post Share on other sites
Casar66 Posted January 29 Report Share Posted January 29 I bought 2 new ones from Bastuck. One failed after 2 weeks, one is still working (since 8 years or so, but poor milage). The failed Bastuck hub was replaced by a refurbish one from Rimmer. That last for 7 years and low milage. It was replaced by a new designed hub from a German dealer, I think that design is also available from English manufactures and should last forever. http://www.trshop.co.uk/newsite/product/uprated-rear-hub-tr4a-tr6/ Quote Link to post Share on other sites

Might want to look at their others parts as additional shipping is probably negligible. Quote Link to post Share on other sites
