    Lower steering shaft rebuild?

    Has anyone had a go at replacing the universals for the lower steering shaft? Are they a standard stock part anywhere, could my local prop-shaft man get them?

    Never done it cos its still ok.
    Did get a nos spare for £50 on ebay though.

    I'll try to measure the bearings when I find the shaft!!

    £5 each or so for the bearings? i think 8 are required


    closed drawm cup needle bearings.

    Not sure about seals though.

    Similar (ish) size here:-



    Paddocks might have a new replacement @£65 ?

      Hi Julian,

      That's pretty much as far as I got, but if the bearing shells are worn I'd expect the cross shafts to be worn as well so that'll need replacing. I was wondering if Triumph had used a stock joint.

      Mine has a wear spot right in the straight-ahead position, the MOT didn't pick it up but it's very annoying. I was hoping it was the bottom ball joints but it wasn't.

        I thought these had staked joints and so were not serviceable? Could be wrong. Anyway, for the cost of a replacement, that's what I did - replace mine.

          The shafts / joints rarely wear.

          The lower column bush wear can appear to be wear in the 'upper' lower shaft u/j though!!!

          Anyway if you need a shaft or the bits perhaps this is helpful:- (?)

          The supply might be drying up of new shafts, but paddocks are listing one at 65 quid.

          This alternative item for a spitfire might yield the bearings and cruciforms though:-

          The staked features are possible to undo & redo once if you approach them carefully, which I'm sure you would

            Strange, the same question came up on another forum quite recently: http://www.club.triumph.org.uk/cgi-b...?m-1458078237/

              Yes, I'd seen that thread.
              Trouble is I've pretty much eliminated everything else (rack, TREs, ball joints, strut top bearings all replaced for other reasons) but there is still this peculiar tight spot in the straight-ahead position which feels just like worn out needle roller bearings. I just ordered a new shaft from Paddocks (£78!) so I'm hoping that will fix it. If not, I'll have a steering shaft for sale.

                Hi Richard,
                Please keep us all informed regarding the tight spot on the steering.

                  Maybe this site might be able to help could be useful to replace staked ujs on drive shafts

                    If the tight spot is just straight ahead, maybe it's more likely to be the rack. If you get a tight spot every full (or half) turn of the wheel, then I'd question the shaft just as you are....

                    Cheers,
                    Mike.

                      Hi Mike,

                      It's a new rack.
                      It probably happens once per revolution, but I'm less likely to notice when I have that much lock on!!

                      I'll let you all know after the weekend, Paddocks have shipped the new shaft so I'll fit it on Saturday.

                        Once the shaft is out, you'll be able to feel a rough or stiff spot by wiggling the UJ's about!

                        Is it a new or recon rack? If the latter, it might be worth checking the thrust button. When I first got the Stag (in 1987!) I fitted a number of recon racks and they were all tight in the straight ahead position so I slightly adjusted the thrust button - and greased it. That seemed to help.

                        Good luck!

                        Cheers,
                        Mike.

                          When i replaced my rack with a reconditioned unit i had a tight spot and it would not centre in a straight line however all i did was to loosen all the rack mounting bolts, turn the steering from lock to lock and then centred the steering again and tightened everything back up.

                          Im not saying that this will cure yours however it sorted mine out

                            The new steering shaft arrived today so I'll try it on Saturday. I'm a little distressed that it doesn't seem to be made to the same quality as the original, but hey ho, that's probably the best we can get.

                            When I say a tight spot, what I really feel is a sort of lump in the rotation so that when turning the wheel it stiffens ever so slightly, then over the lump and frees up again. It's not really a tight spot as in making it difficult to steer a straight line, just that when guiding the car along the motorway at speed it can be a little unsettling to have any unusual feeling through the wheel.

                            I'll let you know how we fare after the weekend!

                              That worked. It's a new shaft from Paddocks - £78 including postage and tax. The steering is as smooth as I wanted it to be. Strange that the old shaft feels lovely off the car, but I'll get the U/J man to see if he can replace the U/Js and then we'll see where the wear is.

                              Onto the next job now.....
