    First thing to do is to centralise the steering rack, There is a hole in the steering racks outer which is found under either a piece of tape or circular cover thingy found in the middle of the rack. Some say this is also for filling rack with oil. You can use a drill bit of equal diameter to make sure that this hole lines up with one in the internal rack. This is the correct way of centralising everything. Now once this has been achieved, centralise the steering wheel. You now know that this is the correct straight ahead position for normal driving. This will position the steering rack knuckles / joints in the optimum position for minimal bump steer. Now you can adjust the track rod ends to make sure the track geometry is correct with the steering wheel in this new perfect straight ahead position.

    You will find the steering column spline is tapered, so if someone has been overzealous with tightening the nut then getting the wheel off can be lots of fun......
    Thanks all for the advice. I will inspect the steering rack to see if my Marina based model has it. Makes such good sense.

    I couldn't get a puller today, but I do have a "bigger hammer". I'll let you know how I get on......

    Well the "bigger hammer" approach paid off.

    I also found a hole in the steering rack so can check the alignment.

    Thanks to all for the advice.

    Also, well done. I was going to sugest putting the nut on the shaft, pulling hard on the steering wheel and hitting the nut with a big hammer. It has worked for me in the past.

    Should warn you, I found the hole is not central and put my steering half a turn more in one direction than other. I counted the turns and halved it and put the wheel on there then adjusted the track rod ends to get the wheels pointing in the right direction.

    Not directly related but somewhere on this forum is the story of someone searching for longer tie Rod ball joints to balance out the centre of fis rack or some suchlike. It turned out, unknown to him that his steering upright on one side had twisted possibly due to accident damage. I would by far prefer that both tie rods should have similar thread engagement, than the rack being centred on a simple hole especially as one end of the steering rack is not adjustable due to its mounting design.
    My opinion is that the hole might help when building a rack, but serves no further help on installation.

    I'm not so sure, I lined mine up that way and never had to adjust it since. Obviously it's worth noting if there is any difference side to side.

    The one I fitted came from a Toyota MR2 if I remember rightly
    Sorry, but I have a supplementary question... That UJ at the rack... I'm trying to buy a new one but can't find a supplier of Marina parts. Does anyone know who might supply it? ... Or, are there alternatives available used on other makes/models? Any helpful advice much appreciated. ~ Tom

    Thanks. I am registered at keep and share but I've not figured out how to get to your pages. Besides, I also went on the Marlin Owners facebook page and got a recommendation for Car Builder Solutions ... and bought the last forged UJ they had in stock. Phew!
