Ciao all.
My name is Martin, im a Mech Eng and CNC Machinist from Australia. With a 2005 Gallardo.
I wanted to share the repair that I have just completed to my upper control arms.
The previous ball joint had 0.50 - 1.00 mm slop. The whole procedure needed to be pretty accurate. +/- .05 mm for a good fixture. My friend helped me with the removal of the front end, we did it on his hoist. We found that a lot of components were corroded. I would recommend a good soak of said components in WD40 prior to removal.
The solution was 100% successful
1 - The original ball joint swage cap was removed.
2 - Excess material docked flat on CNC mill
3 - The ball joint's Delren bush was shimmed. If the Bush is bust then a new bush will need to be machined
4 - M4x0.75 x 6 PCD were drilled and tapped into the control arm to house new billet fixture
5 - Billet fixture was manufactured on CNC
6 - Ball joint base cast mark was removed with Sillicon Carbide polisher
7 - Fitted with HT bolts
If anyone in Australia needs help with this repair I would be happy to assist.
Cheers,
Martin
