I had chrome kingpins and bronze bushes fitted about 4000 miles ago. It has been about 1500 miles since Henrietta had a lube job by Berrybrook just before a 3000 milew rip to France. I have had a lot of difficulty getting hold of a Wanner grease gun = problem solved now I'm glad to say. Managed not get get any grease on me for once!! I have had remote greasing nipples fitted as I have physical difficulty getting under the car. These are a great help.
