Wheel fell off, nearly

Hi all

My 1997 S3 front off side wheel doesn't like my car anymore. The shaft going into the top of the Trunnion sheared off.

First, can anyone advise what I need to repair.

Secondly, It has been suggested I upgrade both front wheel's geometry. If this upgrade makes it stronger and more reliable I might have to dig into the piggy bank. Can anyone advise what I need, to carry out this upgrade.

You need a new upright (vertical link) as its not repairable. A common cause of this is lubricating with grease rather than EP90 gear oil. I would order a new brass trunion too. Looks like caterham are out of stock so perhaps Redline or one of the Triumph specialists?

The stub axle will need removing from the old upright and transferring over. This usually involves some heat and a lump hammer! Also the steering arm.

Regarding geometry there is lots of tweaks / modifications you can do to the old style suspension - what are you looking to achieve?
