Ok just got back from stealer/dealer who dealt with me on the spot.
Seems there was some grease on the bushing and maybe this caused it to slip. Plus killer pot holes here in Fiji...
They took the bushing out and measured it with some calipers and seems it is still round and no signs of damage. So they pushed it back in and have told me to monitor it. I stood over them as they did it and I have just had a look a Dudski's tutorial and notice that they actually put in the bushing 90' off from where the notches are supposed to go and they did not line up the housing properly (8mm above centre point)!
Bush mechanics man!
Wishing I got the powerflex urethane bushings now.
At least they didn't even try to charge me, not that I was going to pay them. Looks like it has chewed my relatively new tyre tho.
I ll keep you all posted.
