Raced for the first time at Southport with the Durga today. it's one of the harshest tracks around for the buggies - I did about 2 corners in practice before one of my rear arms popped out and spat spacers and dogbones around the track.
On closer inspection both the rear balls on the inner rear hingepins were OK but both front balls were in bits - I guess these take the most punishment?
Anyway, I've never had this problem occur before - and with the harsh track I was convinced it would happen again. I replaced the balls in the suspension with more plastic ones - I didn't take my steel replacements with me, oops!
I also added thin metal shims until there was absolutely zero play in the arm (stopped it moving front to back at all). With the arm properly shimmed and the balls pushed firmly into the holders, I didn't have the same problem again.
The car suffered a little understeer so I knocked the front shocks in one hole on the shock tower to give me more mid-corner steering - and the car was pretty nice.
I didn't have a clean run all day but I qualified 8th in the A final but had to leave so didn't get a chance to run the final.
I was a bit cheesed about the arm popping out and it meant I missed practice, but I think if it's properly shimmed it's OK. At least I didn't lose the dogbone though - that' would have been game over!
