Hi Timkee
Just to let you know myself, and a fellow member on here, have been working over the last 9 Months to do exactly that, to come up with a 3200 / 4200 / Gransport front lower control arm whereby the ball joint can be replaced, and not become a throw away expensive item.
To give you the basics, we are using the existing control arm, out with the existing ball joint, drilled, threaded, ball joint re-inserted with new surrounds, grease, springs etc, which then makes the lower control arm ball joint a totally serviceable item for the future, so if the ball joint needs replacing it can be simply unscrewed, insert our new ball joint kit, and away you go. Sounds simple but assure you that has not been the case in design.
Please see pictures below.
We have had a pair of these front lower control arms on a 3200 currently on a car which has covered 10k miles at the moment, without any problems, and we will be soon taking them off, and complete a full analysis of the ball joint as regards wear etc. In hindsight we probably should of done a 4200 pair first and given them to Benny or Mark, probably would have had all the results we needed in 2k miles and 2 days ha ha
Anyway we are progressing, also if anyone has any old 3200 / 4200 front control arms with just the ball joint shot, we need some more for testing.
