Another thing made easy with the lift is a check on the steering. This needed attention.
1. The large nuts (50558) required tightening.
2. 4 thou of shims (52591) were required in king pin.
3 A new spring arm distance tube (50313) and pin (50311) were needed as others were badly worn
4. The holes in the front spring arm were oval and needed welding and reboring.
At some stage in the car's 500000 miles I do not think the lower pin was properly tightened.

Re: Steering check
After replacing the worn out bits of the holes in the spring arm with weld and filing and boring, there is now no movement. It is amazing how play in that lower bolt amplifies into play that seems to come from the track rod. I did learn not to tighten up everything until you have put the upper bolt in as it will not mesh easily into the brass yoke unless exactly in line. So leave some slack so as to align with the bearing inserted in the opposite side, then carefully screw in. It was just possible to get a ring spanner onto the nut in the yoke to tighten it up.
I will take for a test drive and then , if I have time before going to Switzerland, I will check the steering geometry.

Don't forget when you are in the area of the front end of the torsion bars, to check that the bolts in the trunnion bracket are tight, and look for radial cracks from the bolt holes in the front end of the chassis extensions (just behind the end plates where the engine mounts bolt on).
I 'lost' my first Javelin to this malaise and I believe that a number of others have gone the same way.
Repairs in this area are EXTREMELY difficult due to the multiple layers of metal at this point.

My first Javelin suffered failure in this area on tthe drivers side. We removed the Engine, the lower Spring Arm and the Torsion Bar to gain proper access. You could wiggle the front of the Chassis leg about at this point. I designed a repair sub-assembly which allowed the spring arm to be bolted back into its correct position. This sub-assembly was then welded into position which stiffened up the whole area. The repair lasted the life of the car. I must see if I can find the drawing.

Re: Steering check
Amy will well remember our repair on the Jup in Carcassome when the bolt holding the spring arm sheared. We finished the leg out of the Dordogne with the spring arm strapped on with a tow rope. Braking was minimal! Drilling the old bolt out and rethreading for a metric one was a real challenge finished about 1 a.m with a 6 am start the next morning for a trip over the Pyrenees and a hill climb in Andorra.

Re: Steering check
Drummond says 'I must see if I can find the drawing'.
I have in the back of what passes for my mind, a recollection that Dennis Sparrow devised a repair scheme for this too.
This is the sort of thing that ought to be in the Legacy Project - isn't it?

Re: Steering check
Hi there,
A very interesting thread! Yes, Dennis Sparrow helped us 'save' our Javelin. He welded the area where the trunnion brackets bolt on to the chassis, where we had stress cracking around the four horizontal bolts and saved us from some very difficult decisions. Our black Javelin had been used by Ken Lees ( a previous Club Competition Sectretary) and she was probably driven hard in competitions. Dennis did a super job and may well have a jig? I have a vague memory that the Austrailian Club may have repair sections for this area of the chassis? If so, are these stocked by JCS? My motto here is to routinely check that these four bolts and the vertical ones are tight.
On the subject of the cone nuts on the steering link on Javelins, it is vital that the locking washer 'tabs' are folded back over the cone nut flats AND the locking nut. Failure to fold the tabs in both directions may well result in the cone nuts tightening and locking the steering. Believe me, when they lock up, they go very tight and if this happened on the move, you would be in the ditch!
All the best,
David
