    Just a point, if you have a stainless tube manifold fitted check the lower U/J doesn't foul the underneath of the stainless tubes upon certain angles of lock, goes stiff and then loosens off and then stiff again depending upon how bad the interference.

        Thank you guys! I have now soaked the Third UJ in the column, I have checked for rubbing and I have greased the rack. Nothing seems to help.

        The steering is quite a bit lighter when going to one side than the other, could this be a indictation of something? Also, I clearly hear the oil squirting back into the reservoir when turning the steering Wheel. In fact the oil is overflowing the reservoir. This may be because I overfilled after checking the pump, or may this be a indication of something also?

          But have you disconnected the column from the rack to prove/disprove the UJ's are the problem

            Hmm I see that Rimmer is out of stock for LHD Steering Racks. I guess LHD may be hard to find?

                Thank you, I will! I was thinking that soaking them with penetrating oil would outrule them, but I understand that they still may be the problem. I am thinking the best way to check is to drop the rack and split the lower shaft from the rack?

                    Just back to update this very old thread for the archives. (I hate to find threads where the starter does not update with the solution in the end and just leave you wondering...)

                    I ordered a exchange steering rack from Rimmers, when that arrived and I took it out it turned out it was not the problem (it was leaking so I changed it anyway). The splines on the rack are the same as on the column, so it is just a matter of fitting the steering wheel directly to the rack and check!

                    You all were right, it was the UJ's in the lower shaft. I ordered a new lower shaft and it is all good now, except I think the steering feels a little bit stiffer than it was before the problems started. I am thinking this may get better when the rack see a little more use?

                    The conclusion is that even with several days of soaking the UJ's in the lower shaft (and probably also the upper column), they could still be hard to turn and can not be ruled out.

                      Ian. A reconditioned rack is almost invariably a bit stiff till seals etc. have bedded in. Sometimes to the extent that there may even be very little self-centering action. The more you use it, the better it will get.
                      Mike.

                        Often greasing the pinion housing as per the service schedule/ROM can ease a tight one...

                          Thank you, I saw that in the ROM and removed the screw to check. There was no grease there so I fitted a nipple and gave it a couple of strokes. I did not test the rack before that, so I guess the reason is that the seals need a little bedding in like Mike say.

                          I find it strange that Rimmer supply reconditioned racks without grease, especially as you need to find your own grease nipple to be able to do it yourself. If you do not read the ROM, how many will think about this?

                            Well I would because I serviced and repaired them at a Triumph main dealer, but it is something that is so often missed - the grease lubricates the steering damper that helps deal with bump steer, so if it dry it is going to be very stiff as it doesn't get lubrication from anywhere else.

                            I have also fitted 'recon' racks where the damper was adjusted by a gorilla and I've had to correct it to get the feel back - sometimes the rack teeth are a bit worn in the straight ahead position, and the only way to get the play out is to overtighten the damper
