BadBoy1 Posted February 12, 2009 Share Posted February 12, 2009 Hi, I am new here. I have Spitfire mk4 1500. My problem is , that when I turn to the riht or left, (when I am driving), steering wheel dont go back to (straight )position. What could be my problem. I think it is also little harder to turn a wheel, compared to my fathers herald.Thanks for adviceBest regards Jack Link to comment Share on other sites More sharing options...
ferny Posted February 12, 2009 Share Posted February 12, 2009 Does it always go back to the same position, just not dead "straight"? It'll probably be a simple case of removing the wheel and aligning it correctly. Your car will have wider tyres which should make it slightly heavier. And if the steering wheel is smaller you'll notice it even more. I say the wider tyres should make it heavier because on mine it had the opposite affect for some reason!

BadBoy1 Posted February 12, 2009 Author Share Posted February 12, 2009 My tyres are not wider, , I think is is the same, because my father put lil wider tyres on herald, and he has also this small sport steering wheel. And I doesnt go to sraight position. It stays almost in the same position, when I turn. Link to comment Share on other sites More sharing options...
Alex Posted February 12, 2009 Share Posted February 12, 2009 If when normally driving the wheel is straight then there is a possibility you have a seized joint on the steering rack.You say the wheel almost stays in the same position when you turn the wheel?Do you mean the wheel turns but not the steering?If so you may have the wrong boss fitted for your car and its turning on the splines....If you could confirm what fault you have it may make diagnosis easier.Alex Link to comment Share on other sites More sharing options...
junkuser Posted February 12, 2009 Share Posted February 12, 2009 Sounds like lack of lubrication. Link to comment Share on other sites More sharing options...
Alex Posted February 12, 2009 Share Posted February 12, 2009 Partial seize on the knuckle is my guess if its just a case of not returning to straight ahead. Link to comment Share on other sites More sharing options...
thescrapman Posted February 12, 2009 Share Posted February 12, 2009 I think that you need some castor to get self centring steering. Have you had the front suspension apart??I would also suspect a re-con rack, especially if it is one of the cheaper oneas where they are setup at straight ahead, and are thus very stiff away from that position.I lost a bit of my self-centring when put the wider tyres on my spitfire.CheersColin Link to comment Share on other sites More sharing options...
BadBoy1 Posted February 12, 2009 Author Share Posted February 12, 2009 Hm, maybe I didnt write understandly. When I turn steering wheel, whels turns too. There is no problem. But problem is If I go let say to the left corner, I turn to the left, but normaly when you release steering wheel while driving, it goes to normal straight position. But in my car it stay in the same position, so that means I have manualystraightened car. I hope you understand my problem. And sorry for my language mistakes ;) Link to comment Share on other sites More sharing options...
Alex Posted February 12, 2009 Share Posted February 12, 2009 Is it a new problem or something as a result of a change of parts.Colin(scrapman) diagnosis sounds good if youe recently aquired the car and its always done it.It could be beneficial to get the car tracked etc.If its something thats been recommisioned the chances of something having seized is quite likely.oh and dont apologise about language/spelling mistakes we all do it....sometimes its difficult to explain even the simplest things without using my hands... :BAlex Link to comment Share on other sites More sharing options...
Clive Posted February 12, 2009 Share Posted February 12, 2009 Hmm, I suspect a proper wheel/camber/castor setup at a specialist is in order.... Link to comment Share on other sites More sharing options...

mikeyb Posted February 12, 2009 Share Posted February 12, 2009 It could be badly adjusted tracking ( ie. front wheel toe-in or toe out alignment). When I fitted power steering to the PI, the replacement rack had no ball joints so I had to fit new and guess how far on to screw them! The alignment when checked was off the scale of the gauge- when I drove to the garage for the checks, self centering was poor. When adjusted correctly, back to normal again.

Richard B Posted February 12, 2009 Share Posted February 12, 2009 I've had this on the big cars and it was a siezed steering coupling. I would jack the car up and investigate all the ball joints, trunnions etc. I would suspect something has siezed and is not allowing it to return.

Howard81 Posted February 13, 2009 Share Posted February 13, 2009 I had this problem on my Dolomite Sprint - it was a bent steering rack. After I replaced the rack and steering knuckles, the problem went away! Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 13, 2009 Share Posted February 13, 2009 As said this has to be seized trunions,, get the thing off the deck quick and check ,best if you disconnect the track rod ends to test the free state of the upright to swivel., and the ease of the rack if they are stiff get them off the car clean out the brass trunion thread and fully examine the state of the uprights thread, any errosion/corrosion on this where water has been will ultimatley cause a stress fracture to start...it finishes with a wrecked car and recoverywhile they're off get some new sealing plugs for the base of the trunion and only use ep90 or ep140 OIL never grease them , Pete Link to comment Share on other sites More sharing options...

JackThe trunion is the brass swivel joint at the bottom of the vertical links and consist of a threaded area Male on the vertical link Female on the brass trunion, These threads can sieze up if neglected or greased they should be lubricated with 90 gear oil.

mark spit Posted February 13, 2009 Share Posted February 13, 2009 It's the brass bit that the bottom of the vertical link screws into, this is then secured into the outer end of the bottom wishbone with a bolt.YoursMark Link to comment Share on other sites More sharing options...
Freebird Posted February 13, 2009 Share Posted February 13, 2009 Hi Bad boyI have dug through my pictures and found this one showning the trunnion still fitted to the upright, but off the car. I hope it helps you to identify yours. Fix it NOW, don't drive it until you have fixed it or you risk a very nasty crash. The thread part (inside the part with the red cirle round it) can snap right off leaving you with no control at all. Link to comment Share on other sites More sharing options...
mikeyb Posted February 13, 2009 Share Posted February 13, 2009 like this! I'm led to believe that this didn't fail in the usual place . . . . but if you look carefully on the LH section, you will see a second crack in that usual place! Link to comment Share on other sites More sharing options...
esxefi Posted February 13, 2009 Share Posted February 13, 2009 excluding the normal rust related cause of failure,i would expect that to be the most likely point to break as the cross section is at it's thinnest at the bottom of the thread trough ,plus stress raisers from the cutting of the thread during manufacture could be another reason.either way that was gonna go.
